jQuery add(selector), add(element) and add(html) example

jQuery add() API can be used to add elements, selectors or html to the matched elements.

The add() method is very useful if you want to apply any jQuery function or add CSS to DOM elements in HTML.

Below example shows how we can use add() to apply CSS styles to ‘table’, ‘p’ and ‘li’ DOM elements in a single line, otherwise we had to apply styles on each element one by one. It also shows how can we add HTML to any DOM element.

<script type="text/javascript" src="jquery-1.8.3.min.js"></script>
<style type="text/css">
	border:1px black solid;
	background-color: read;
	border-collapse: collapse;
<script type="text/javascript">

	function styleToggle(button) {
		if (button.value == 'Add Style') {
			//using add() we can apply css to all the elements at once
			$('table').add('p').addClass('styled').add('li').css('background-color', 'red');
			button.value = 'Remove Style';
		} else {
			//using removeAttr() to remove the styling
			button.value = 'Add Style';
		$().add("<br /><strong>appending html</strong>").appendTo("p:last");
