How to select elements by attribute in jQuery ?

jQuery is a lightweight JavaScript library. In the vanilla JavaScript language, the getElementById method is used to select an element. However, jQuery provides a much lighter alternative for the same purpose. The 'jQuery Selector' allows the user to manipulate HTML elements and the data inside it(DOM manipulation). Syntax

$("[attribute=value]")

Here, attribute and value are mandatory. Some of the most commonly used jQuery selectors

Syntax	Example	Selection
*	$("*")	All elements on the webpage
#id	$("#geeks")	Elements with id="geeks"
.class	$(".geeks")	All elements with class="geeks"
:first	$("p:first")	First 'p' element of the webpage
:header	$(":header")	All the header elements like h1, h2, h3, h4 etc
:empty	$(":empty")	All the empty elements
:input	$(":input")	All the input elements like text, password etc
:text	$(":text")	Input elements with type="text"
:last-child	$("p:last-child")	Those 'p' elements that are the last child of their parents
:animated	$(":animated")	All the animated elements on the webpage

#id Selector: The #id selector specifies an id for an element to be selected. It should not begin with a number and the id attribute must be unique within a document which means it can be used only one time. Syntax:

$("#example")

The id selector must be used only when the user wants to find a unique element. Example:

html

<!DOCTYPE html>
<html>
    
<head>
    <title>
