HTML

HTML stands for Hypertext Markup Language, and it is the most widely used language to
write Web Pages.
 Hypertext refers to the way in which Web pages (HTML documents) are linked
together. Thus, the link available on a webpage is called Hypertext.
 As its name suggests, HTML is a Markup Language which means you use HTML to
simply "mark-up" a text document with tags that tell a Web browser how to structure
it to display.
Originally, HTML was developed with the intent of defining the structure of documents like
headings, paragraphs, lists, and so forth to facilitate the sharing of scientific information
between researchers.
Now, HTML is being widely used to format web pages with the help of different tags available
in HTML language.
BasicHTMLDocument
In its simplest form, following is an example of an HTML document:
<!DOCTYPE html>
<html>
<head>
<title>This is document title</title>
</head>
<body>
<h1>This is a heading</h1>
<p>Document content goes here.....</p>
</body>
</html>
Either you can use Try it option available at the top right corner of the code box to check the
result of this HTML code, or let's save it in an HTML file test.htm using your favorite text
editor. Finally open it using a web browser like Internet Explorer or Google Chrome, or Firefox
etc. It must show the following output:
1. HTML – OVERVIEW

HTML

HTMLTags
As told earlier, HTML is a markup language and makes use of various tags to format the
content. These tags are enclosed within angle braces <Tag Name>. Except few tags, most
of the tags have their corresponding closing tags. For example, <html> has its closing
tag</html> and <body> tag has its closing tag </body> tag etc.
Above example of HTML document uses the following tags:
Tag Description
<!DOCTYPE...> This tag defines the document type and HTML version.
<html>
This tag encloses the complete HTML document and mainly comprises
of document header which is represented by <head>...</head> and
document body which is represented by <body>...</body> tags.
<head>
This tag represents the document's header which can keep other HTML
tags like <title>, <link> etc.
<title>
The <title> tag is used inside the <head> tag to mention the
document title.
<body>
This tag represents the document's body which keeps other HTML tags
like <h1>, <div>, <p> etc.
<h1> This tag represents the heading.

HTML
18
<p> This tag represents a paragraph.
To learn HTML, you will need to study various tags and understand how they behave, while
formatting a textual document. Learning HTML is simple as users have to learn the usage of
different tags in order to format the text or images to make a beautiful webpage.
World Wide Web Consortium (W3C) recommends to use lowercase tags starting from HTML
4.
HTMLDocumentStructure
A typical HTML document will have the following structure:
Document declaration tag
<html>
<head>
Document header related tags
</head>
<body>
Document body related tags
</body>
</html>
We will study all the header and body tags in subsequent chapters, but for now let's see what
is document declaration tag.
The<!DOCTYPE>Declaration
The <!DOCTYPE> declaration tag is used by the web browser to understand the version of
the HTML used in the document. Current version of HTML is 5 and it makes use of the following
declaration:
<!DOCTYPE html>
There are many other declaration types which can be used in HTML document depending on
what version of HTML is being used. We will see more details on this while discussing
<!DOCTYPE...> tag along with other HTML tags.

HTML
19
HeadingTags
Any document starts with a heading. You can use different sizes for your headings. HTML also
has six levels of headings, which use the elements <h1>, <h2>, <h3>, <h4>, <h5>, and
<h6>. While displaying any heading, browser adds one line before and one line after that
heading.
Example
<!DOCTYPE html>
<html>
<head>
<title>Heading Example</title>
</head>
<body>
<h1>This is heading 1</h1>
</body>
</html>
This will produce the following result:
2. HTML – BASIC TAGS

HTML
20
ParagraphTag
The <p> tag offers a way to structure your text into different paragraphs. Each paragraph of
text should go in between an opening <p> and a closing </p> tag as shown below in the
example:
Example
<!DOCTYPE html>
<html>
<head>
<title>Paragraph Example</title>
</head>
<body>
<p>Here is a first paragraph of text.</p>
<p>Here is a second paragraph of text.</p>
<p>Here is a third paragraph of text.</p>
</body>
</html>
Here is a first paragraph of text.
Here is a second paragraph of text.
Here is a third paragraph of text.

HTML
21
LineBreakTag
Whenever you use the <br /> element, anything following it starts from the next line. This
tag is an example of an empty element, where you do not need opening and closing tags, as
there is nothing to go in between them.
The <br /> tag has a space between the characters br and the forward slash. If you omit this
space, older browsers will have trouble rendering the line break, while if you miss the forward
slash character and just use <br> it is not valid in XHTML.
Example
<!DOCTYPE html>
<html>
<head>
<title>Line Break Example</title>
</head>
<body>
<p>Hello<br />
You delivered your assignment on time.<br />
Thanks<br />
Mahnaz</p>
</body>
</html>
Hello
You delivered your assignment on time.
Thanks
Mahnaz
CenteringContent
You can use <center> tag to put any content in the center of the page or any table cell.
Example
<!DOCTYPE html>
<html>
<head>

HTML
22
<title>Centring Content Example</title>
</head>
<body>
<p>This text is not in the center.</p>
<center>
<p>This text is in the center.</p>
</center>
</body>
</html>
This text is not in the center.
This text is in the center.
HorizontalLines
Horizontal lines are used to visually break-up sections of a document. The <hr> tag creates
a line from the current position in the document to the right margin and breaks the line
accordingly.
For example, you may want to give a line between two paragraphs as in the given example
below:
Example
<!DOCTYPE html>
<html>
<head>
<title>Horizontal Line Example</title>
</head>
<body>
<p>This is paragraph one and should be on top</p>
<hr />
<p>This is paragraph two and should be at bottom</p>
</body>
</html>

HTML
23
This is paragraph one and should be on top
This is paragraph two and should be at bottom
Again <hr /> tag is an example of the empty element, where you do not need opening and
closing tags, as there is nothing to go in between them.
The <hr /> element has a space between the characters hr and the forward slash. If you
omit this space, older browsers will have trouble rendering the horizontal line, while if you
miss the forward slash character and just use <hr> it is not valid in XHTML
PreserveFormatting
Sometimes, you want your text to follow the exact format of how it is written in the HTML
document. In these cases, you can use the preformatted tag <pre>.
Any text between the opening <pre> tag and the closing </pre> tag will preserve the
formatting of the source document.
Example
<!DOCTYPE html>
<html>
<head>
<title>Preserve Formatting Example</title>
</head>
<body>
<pre>
function testFunction( strText ){
alert (strText)
}
</pre>
</body>
</html>
function testFunction( strText ){

HTML
24
alert (strText)
}
Try using the same code without keeping it inside <pre>...</pre> tags
NonbreakingSpaces
Suppose you want to use the phrase "12 Angry Men." Here, you would not want a browser to
split the "12, Angry" and "Men" across two lines:
An example of this technique appears in the movie "12 Angry Men."
In cases, where you do not want the client browser to break text, you should use a
nonbreaking space entity   instead of a normal space. For example, when coding the
"12 Angry Men" in a paragraph, you should use something similar to the following code:
Example
<!DOCTYPE html>
<html>
<head>
<title>Nonbreaking Spaces Example</title>
</head>
<body>
<p>An example of this technique appears in the movie "12 Angry Men."</p>
</body>
</html>

HTML
25
An HTML element is defined by a starting tag. If the element contains other content, it ends
with a closing tag, where the element name is preceded by a forward slash as shown below
with few tags:
Start Tag Content End Tag
<p> This is paragraph content. </p>
<h1> This is heading content. </h1>
<div> This is division content. </div>
<br />
So here <p>....</p> is an HTML element, <h1>...</h1> is another HTML element. There
are some HTML elements which don't need to be closed, such as <img.../>, <hr /> and
<br /> elements. These are known as void elements.
HTML documents consists of a tree of these elements and they specify how HTML documents
should be built, and what kind of content should be placed in what part of an HTML document.
HTMLTagvs.Element
An HTML element is defined by a starting tag. If the element contains other content, it ends
with a closing tag.
For example, <p> is starting tag of a paragraph and </p> is closing tag of the same
paragraph but <p>This is paragraph</p> is a paragraph element.
NestedHTMLElements
It is very much allowed to keep one HTML element inside another HTML element:
Example
<!DOCTYPE html>
<html>
3. HTML – ELEMENTS

HTML
26
<head>
<title>Nested Elements Example</title>
</head>
<body>
<h1>This is <i>italic</i> heading</h1>
<p>This is <u>underlined</u> paragraph</p>
</body>
</html>
This will display the following result:
This is italic heading
This is underlined paragraph

HTML
27
We have seen few HTML tags and their usage like heading tags <h1>, <h2>, paragraph tag
<p> and other tags. We used them so far in their simplest form, but most of the HTML tags
can also have attributes, which are extra bits of information.
An attribute is used to define the characteristics of an HTML element and is placed inside the
element's opening tag. All attributes are made up of two parts: a name and a value:
 The name is the property you want to set. For example, the paragraph <p> element
in the example carries an attribute whose name is align, which you can use to indicate
the alignment of paragraph on the page.

 The value is what you want the value of the property to be set and always put within
quotations. The below example shows three possible values of align attribute: left,
center and right.
Attribute names and attribute values are case-insensitive. However, the World Wide Web
Consortium (W3C) recommends lowercase attributes/attribute values in their HTML 4
recommendation.
Example
<!DOCTYPE html>
<html>
<head>
<title>Align Attribute Example</title>
</head>
<body>
<p align="left">This is left aligned</p>
<p align="center">This is center aligned</p>
<p align="right">This is right aligned</p>
</body>
</html>
This will display the following result:
This is left aligned
This is center aligned
4. HTML – ATTRIBUTES

HTML
28
This is right aligned
CoreAttributes
The four core attributes that can be used on the majority of HTML elements (although not all)
are:
 Id
 Title
 Class
 Style
TheIdAttribute
The id attribute of an HTML tag can be used to uniquely identify any element within an HTML
page. There are two primary reasons that you might want to use an id attribute on an
element:
 If an element carries an id attribute as a unique identifier, it is possible to identify just
that element and its content.
 If you have two elements of the same name within a Web page (or style sheet), you
can use the id attribute to distinguish between elements that have the same name.
We will discuss style sheet in separate tutorial. For now, let's use the id attribute to distinguish
between two paragraph elements as shown below.
Example
<p id="html">This para explains what is HTML</p>
<p id="css">This para explains what is Cascading Style Sheet</p>
ThetitleAttribute
The title attribute gives a suggested title for the element. They syntax for the title attribute
is similar as explained for id attribute:
The behavior of this attribute will depend upon the element that carries it, although it is often
displayed as a tooltip when cursor comes over the element or while the element is loading.
Example
<!DOCTYPE html>
<html>
<head>

HTML
29
<title>The title Attribute Example</title>
</head>
<body>
<h3 title="Hello HTML!">Titled Heading Tag Example</h3>
</body>
</html>
Titled Heading Tag Example
Now try to bring your cursor over "Titled Heading Tag Example" and you will see that whatever
title you used in your code is coming out as a tooltip of the cursor.
TheclassAttribute
The class attribute is used to associate an element with a style sheet, and specifies the class
of element. You will learn more about the use of the class attribute when you will learn
Cascading Style Sheet (CSS). So for now you can avoid it.
The value of the attribute may also be a space-separated list of class names. For example:
class="className1 className2 className3"
ThestyleAttribute
The style attribute allows you to specify Cascading Style Sheet (CSS) rules within the element.
<!DOCTYPE html>
<html>
<head>
<title>The style Attribute</title>
</head>
<body>
<p style="font-family:arial; color:#FF0000;">Some text...</p>
</body>
</html>

HTML
30
Some text...
At this point of time, we are not learning CSS, so just let's proceed without bothering much
about CSS. Here, you need to understand what are HTML attributes and how they can be
used while formatting content.
InternationalizationAttributes
There are three internationalization attributes, which are available for most (although not all)
XHTML elements.
 dir
 lang
 xml:lang
ThedirAttribute
The dir attribute allows you to indicate to the browser about the direction in which the text
should flow. The dir attribute can take one of two values, as you can see in the table that
follows:
Value Meaning
ltr Left to right (the default value)
rtl Right to left (for languages such as Hebrew or Arabic that are read right to left)
Example
<!DOCTYPE html>
<html dir="rtl">
<head>
<title>Display Directions</title>
</head>
<body>
This is how IE 5 renders right-to-left directed text.
</body>
</html>

HTML
31
This is how IE 5 renders right-to-left directed text.
When dir attribute is used within the <html> tag, it determines how text will be presented
within the entire document. When used within another tag, it controls the text's direction for
just the content of that tag.
ThelangAttribute
The lang attribute allows you to indicate the main language used in a document, but this
attribute was kept in HTML only for backwards compatibility with earlier versions of HTML.
This attribute has been replaced by the xml:lang attribute in new XHTML documents.
The values of the lang attribute are ISO-639 standard two-character language codes. Check
HTML Language Codes: ISO 639 for a complete list of language codes.
Example
<!DOCTYPE html>
<html lang="en">
<head>
<title>English Language Page</title>
</head>
<body>
This page is using English Language
</body>
</html>
Thexml:langAttribute
The xml:lang attribute is the XHTML replacement for the lang attribute. The value of
thexml:lang attribute should be an ISO-639 country code as mentioned in previous section.
GenericAttributes
Here's a table of some other attributes that are readily usable with many of the HTML tags.
Attribute Options Function
align right, left, center Horizontally aligns tags

HTML
32
valign top, middle, bottom Vertically aligns tags within an HTML
element.
bgcolor numeric, hexidecimal, RGB
values
Places a background color behind an
element
background URL Places a background image behind an
element
id User Defined Names an element for use with Cascading
Style Sheets.
class User Defined Classifies an element for use with Cascading
Style Sheets.
width Numeric Value Specifies the width of tables, images, or
table cells.
height Numeric Value Specifies the height of tables, images, or
table cells.
title User Defined "Pop-up" title of the elements.
We will see related examples as we will proceed to study other HTML tags. For a complete list
of HTML Tags and related attributes please check reference to HTML Tags List.

HTML
33
If you use a word processor, you must be familiar with the ability to make text bold, italicized,
or underlined; these are just three of the ten options available to indicate how text can appear
in HTML and XHTML.
BoldText
Anything that appears within <b>...</b> element, is displayed in bold as shown below:
Example
<!DOCTYPE html>
<html>
<head>
<title>Bold Text Example</title>
</head>
<body>
<p>The following word uses a <b>bold</b> typeface.</p>
</body>
</html>
The following word uses a bold typeface.
ItalicText
Anything that appears within <i>...</i> element is displayed in italicized as shown below:
Example
<!DOCTYPE html>
<html>
<head>
<title>Italic Text Example</title>
</head>
5. HTML – FORMATTING

HTML
34
<body>
<p>The following word uses a <i>italicized</i> typeface.</p>
</body>
</html>

UnderlinedText
Anything that appears within <u>...</u> element, is displayed with underline as shown
below:
Example
<!DOCTYPE html>
<html>
<head>
<title>Underlined Text Example</title>
</head>
<body>
<p>The following word uses a <u>underlined</u> typeface.</p>
</body>

</head>
<body>
<p>The following word uses a <strike>strikethrough</strike> typeface.</p>
</body>
</html>
The following word uses a strikethrough typeface.
MonospacedFont
The content of a <tt>...</tt> element is written in monospaced font. Most of the fonts are
known as variable-width fonts because different letters are of different widths (for example,
the letter 'm' is wider than the letter 'i'). In a monospaced font, however, each letter has the
same width.
Example
<!DOCTYPE html>
<html>
<head>
<title>Monospaced Font Example</title>
</head>
<body>
<p>The following word uses a <tt>monospaced</tt> typeface.</p>
</body>
</html>
The following word uses a monospaced typeface.
SuperscriptText
The content of a <sup>...</sup> element is written in superscript; the font size used is the
same size as the characters surrounding it but is displayed half a character's height above
the other characters.

HTML
36
Example
<!DOCTYPE html>
<html>
<head>
<title>Superscript Text Example</title>
</head>
<body>
<p>The following word uses a <sup>superscript</sup> typeface.</p>
</body>
</html>
The following word uses a superscript typeface.
SubscriptText
The content of a <sub>...</sub> element is written in subscript; the font size used is the
same as the characters surrounding it, but is displayed half a character's height beneath the
other characters.
Example
<!DOCTYPE html>
<html>
<head>
<title>Subscript Text Example</title>
</head>
<body>
<p>The following word uses a <sub>subscript</sub> typeface.</p>
</body>
</html>
The following word uses a subscript typeface.

HTML
37
InsertedText
Anything that appears within <ins>...</ins> element is displayed as inserted text.
Example
<!DOCTYPE html>
<html>
<head>
<title>Inserted Text Example</title>
</head>
<body>
<p>I want to drink <del>cola</del> <ins>wine</ins></p>
</body>
</html>
DeletedText
Anything that appears within <del>...</del> element, is displayed as deleted text.
Example
<!DOCTYPE html>
<html>
<head>
<title>Deleted Text Example</title>
</head>
<body>
<p>I want to drink <del>cola</del> <ins>wine</ins></p>
</body>
</html>

HTML
38
LargerText
The content of the <big>...</big> element is displayed one font size larger than the rest of
the text surrounding it as shown below:
Example
<!DOCTYPE html>
<html>
<head>
<title>Larger Text Example</title>
</head>
<body>
<p>The following word uses a <big>big</big> typeface.</p>
</body>
</html>
The following word uses a big typeface.
SmallerText
The content of the <small>...</small> element is displayed one font size smaller than the
rest of the text surrounding it as shown below:
Example
<!DOCTYPE html>
<html>
<head>
<title>Smaller Text Example</title>
</head>
<body>
<p>The following word uses a <small>small</small> typeface.</p>
</body>

HTML
39
</html>
The following word uses a small typeface.
GroupingContent
The <div> and <span> elements allow you to group together several elements to create
sections or subsections of a page.
For example, you might want to put all of the footnotes on a page within a <div> element to
indicate that all of the elements within that <div> element relate to the footnotes. You might
then attach a style to this <div> element so that they appear using a special set of style
rules.
Example
<!DOCTYPE html>
<html>
<head>
<title>Div Tag Example</title>
</head>
<body>
<div id="menu" align="middle" >
<a href="/index.htm">HOME</a> |
<a href="/about/contact_us.htm">CONTACT</a> |
<a href="/about/index.htm">ABOUT</a>
</div>
<div id="content" align="left" bgcolor="white">
<h5>Content Articles</h5>
<p>Actual content goes here.....</p>
</div>
</body>
</html>

HTML
40
HOME | CONTACT | ABOUT
CONTENT ARTICLES
Actual content goes here.....
The <span> element, on the other hand, can be used to group inline elements only. So, if
you have a part of a sentence or paragraph which you want to group together, you could use
the <span> element as follows
Example
<!DOCTYPE html>
<html>
<head>
<title>Span Tag Example</title>
</head>
<body>
<p>This is the example of <span style="color:green">span tag</span> and the <span
style="color:red">div tag</span> alongwith CSS</p>
</body>
</html>
This is the example of span tag and the div tag along with CSS
These tags are commonly used with CSS to allow you to attach a style to a section of a page.

HTML
41
The phrase tags have been desicolgned for specific purposes, though they are displayed in a
similar way as other basic tags like <b>, <i>, <pre>, and <tt>, you have seen in previous
chapter. This chapter will take you through all the important phrase tags, so let's start seeing
them one by one.
EmphasizedText
Anything that appears within <em>...</em> element is displayed as emphasized text.
Example
<!DOCTYPE html>
<html>
<head>
<title>Emphasized Text Example</title>
</head>
<body>
<p>The following word uses a <em>emphasized</em> typeface.</p>
</body>
</html>
The following word uses an emphasized typeface.
MarkedText
Anything that appears with-in <mark>...</mark> element, is displayed as marked with
yellow ink.
Example
<!DOCTYPE html>
<html>
<head>
<title>Marked Text Example</title>
6. HTML – PHRASE TAGS

HTML
42
</head>
<body>
<p>The following word has been <mark>marked</mark> with yellow</p>
</body>
</html>
The following word has been marked with yellow.
StrongText
Anything that appears within <strong>...</strong> element is displayed as important text.
Example
<!DOCTYPE html>
<html>
<head>
<title>Strong Text Example</title>
</head>
<body>
<p>The following word uses a <strong>strong</strong> typeface.</p>
</body>
</html>
The following word uses a strong typeface.
TextAbbreviation
You can abbreviate a text by putting it inside opening <abbr> and closing </abbr> tags. If
present, the title attribute must contain this full description and nothing else.
Example
<!DOCTYPE html>
<html>
<head>

HTML
43
<title>Text Abbreviation</title>
</head>
<body>
<p>My best friend's name is <abbr title="Abhishek">Abhy</abbr>.</p>
</body>
</html>
My best friend's name is Abhy.
AcronymElement
The <acronym> element allows you to indicate that the text between <acronym> and
</acronym> tags is an acronym.
At present, the major browsers do not change the appearance of the content of the
<acronym> element.
Example
<!DOCTYPE html>
<html>
<head>
<title>Acronym Example</title>
</head>
<body>
<p>This chapter covers marking up text in <acronym>XHTML</acronym>.</p>
</body>
</html>
This chapter covers marking up text in XHTML.
TextDirection
The <bdo>...</bdo> element stands for Bi-Directional Override and it is used to override
the current text direction.

HTML
44
Example
<!DOCTYPE html>
<html>
<head>
<title>Text Direction Example</title>
</head>
<body>
<p>This text will go left to right.</p>
<p><bdo dir="rtl">This text will go right to left.</bdo></p>
</body>
</html>
This text will go left to right.
This text will go right to left.
SpecialTerms
The <dfn>...</dfn> element (or HTML Definition Element) allows you to specify that you
are introducing a special term. It's usage is similar to italic words in the midst of a paragraph.
Typically, you would use the <dfn> element the first time you introduce a key term. Most
recent browsers render the content of a <dfn> element in an italic font.
Example
<!DOCTYPE html>
<html>
<head>
<title>Special Terms Example</title>
</head>
<body>
<p>The following word is a <dfn>special</dfn> term.</p>
</body>
</html>

HTML
45
The following word is a special term.
QuotingText
When you want to quote a passage from another source, you should put it in
between<blockquote>...</blockquote> tags.
Text inside a <blockquote> element is usually indented from the left and right edges of the
surrounding text, and sometimes uses an italicized font.
Example
<!DOCTYPE html>
<html>
<head>
<title>Blockquote Example</title>
</head>
<body>
<p>The following description of XHTML is taken from the W3C Web site:</p>
<blockquote>XHTML 1.0 is the W3C's first Recommendation for XHTML, following on
from earlier work on HTML 4.01, HTML 4.0, HTML 3.2 and HTML 2.0.</blockquote>
</body>
</html>
The following description of XHTML is taken from the W3C Web site:
XHTML 1.0 is the W3C's first Recommendation for XHTML, following on from earlier
work on HTML 4.01, HTML 4.0, HTML 3.2 and HTML 2.0.
ShortQuotations
The <q>...</q> element is used when you want to add a double quote within a sentence.
Example
<!DOCTYPE html>
<html>
<head>

HTML
46
<title>Double Quote Example</title>
</head>
<body>
<p>Amit is in Spain, <q>I think I am wrong</q>.</p>
</body>
</html>
Amit is in Spain, I think I am wrong.
TextCitations
If you are quoting a text, you can indicate the source placing it between an opening <cite>tag
and closing </cite> tag
As you would expect in a print publication, the content of the <cite> element is rendered in
italicized text by default.
Example
<!DOCTYPE html>
<html>
<head>
<title>Citations Example</title>
</head>
<body>
<p>This HTML tutorial is derived from <cite>W3 Standard for HTML</cite>.</p>
</body>
</html>
This HTML tutorial is derived from W3 Standard for HTML.
ComputerCode
Any programming code to appear on a Web page should be placed
inside <code>...</code>tags. Usually the content of the <code> element is presented in a
monospaced font, just like the code in most programming books.

HTML
47
Example
<!DOCTYPE html>
<html>
<head>
<title>Computer Code Example</title>
</head>

HTML lets you specify metadata - additional important information about a document in a
variety of ways. The META elements can be used to include name/value pairs describing
properties of the HTML document, such as author, expiry date, a list of keywords, document
author etc.
The <meta> tag is used to provide such additional information. This tag is an empty element
and so does not have a closing tag but it carries information within its attributes.
You can include one or more meta tags in your document based on what information you
want to keep in your document but in general, meta tags do not impact physical appearance
of the document so from appearance point of view, it does not matter if you include them or
not.
AddingMetaTagstoYourDocuments
You can add metadata to your web pages by placing <meta> tags inside the header of the
document which is represented by <head> and </head> tags. A meta tag can have
following attributes in addition to core attributes:
Attribute Description
Name Name for the property. Can be anything. Examples include, keywords,
description, author, revised, generator etc.
content Specifies the property's value.
scheme Specifies a scheme to interpret the property's value (as declared in the
content attribute).
http-
equiv
Used for http response message headers. For example, http-equiv can be
used to refresh the page or to set a cookie. Values include content-type,
expires, refresh and set-cookie.
SpecifyingKeywords
You can use <meta> tag to specify important keywords related to the document and later
these keywords are used by the search engines while indexing your webpage for searching
purpose.

used by various search engines while indexing your webpage for searching purpose.
Example

DocumentRevisionDate
You can use <meta> tag to give information about when last time the document was updated.
This information can be used by various web browsers while refreshing your webpage.
Example

<html>
<head>
<meta name="revised" content="Tutorialspoint, 3/7/2014" />
</head>
<body>

DocumentRefreshing
A <meta> tag can be used to specify a duration after which your web page will keep refreshing
automatically.
Example
If you want your page keep refreshing after every 5 seconds then use the following syntax.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="5" />

duration if you want to redirect the page after a certain number of seconds.
Example
Following is an example of redirecting current page to another page after 5 seconds. If you
want to redirect page immediately then do not specify content attribute.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="5; url=http://www.tutorialspoint.com" />

</body>
</html>

web browser and web server to keep track of various information based on your web
application need.
You can use <meta> tag to store cookies on client side and later this information can be used
