The ::before and ::after Pseudo-element in CSS
The CSS ::before and CSS ::after Pseudo-element are used to insert some content before and after the element respectively.
The ::after pseudo element
If you want to insert a content after an element, then use the ::after pseudo-element. The content to be placed after is set using the content attribute −
p::after {
content: " is Virat Kohli";
background-color: red;
font-weight: bold;
}
Example
Let us see the example −
<!DOCTYPE html>
<html>
<head>
<style>
p {
background-color: blue;
color: white;
}
p::after {
content: " is Virat Kohli";
background-color: red;
font-weight: bold;
}
</style>
</head>
<body>
<h1>Cricket is love</h1>
<p>Favourite Cricketer</p>
<p>Favourite Batsman</p>
</body>
</html>
The ::before pseudo element
If you want to insert a content before an element, then use the ::before pseudo-element. The content to be placed after is set using the content attribute −
p::before {
content: "Virat Kohli:";
background-color: red;
font-weight: bold;
}
Example
Let us see the example −
<!DOCTYPE html>
<html>
<head>
<style>
p {
background-color: blue;
color: white;
}
p::before {
content: "Virat Kohli:";
background-color: red;
font-weight: bold;
}
</style>
</head>
<body>
<h1>Cricket is love</h1>
<p>Favourite Cricketer</p>
<p>Favourite Batsman</p>
</body>
</html>
Example
Let's see an example for CSS ::before and CSS ::after Pseudo-elements −
<!DOCTYPE html>
<html>
<head>
<style>
div:nth-of-type(1) p:nth-child(2)::after {
content: " BUZZINGA!";
background: orange;
padding: 5px;
}
div:nth-of-type(2) p:nth-child(2)::before {
content: "Harry:";
background-color: lightblue;
font-weight: bold;
padding: 5px;
}
</style>
</head>
<body>
<div>
<p>Nobody: </p>
<p>Sheldon Cooper:</p>
</div><hr>
<div>
<p><q>Death Eaters arrive</q></p>
<p><q>Expecto Patronum!</q></p>
</div>
</body>
</html>
