What is jQuery?

jQuery is the most popular framework of JavaScript. Different browsers execute JavaScript, use different techniques to display results in the browser. jQuery brings these capabilities to a unique format. As a result, JavaScript code can be easily written here. jQuery is also called cross-browser JavaScript library.

Many browsers “: nth-child (n)” does not support Pseudo-class, we can easily support it through jQuery.

Example Code:

<title> www.mydemo.com</title>
<style type="text/css">
<body >
<ul class="emphasis">
<li>item 1</li>
<li>item 2</li>
<li>item 3</li>

$ (‘Ul.emphasis’) children (‘li’). First (). AddClass (‘arif’); In this case, the arif class will be added to the first li under ul.emphasis.

<style type = “text / css”>
ul li: nth-child (1) {
color: blue;
</ style>

The same work will be done by this css. But the difference is that css code will not support many browsers, jQuery code will support all browsers.
