HTML provides 6 tags to create headings i.e. h1, h2, h3, h4, h5 and h6. Use any of the heading tags <h1> to <h6> and every tag will give you the different size of the heading. The <h1>tag defines the most important heading and <h6> defines the least important heading.
Just keep in mind that you should use these tags inside <body>…</body> tags.
Example
You can try to run the following code to create different headings in an HTML page
<!DOCTYPE html> <html> <head> <title>HTML Headings</title> </head> <body> <h1>This is heading 1</h1> <h2>This is heading 2</h2> <h3>This is heading 3</h3> <h4>This is heading 4</h4> <h5>This is heading 5</h5> <h6>This is heading 6</h6> </body> </html>
