Pseudo Elements are special keywords that allow us to style specific parts of an element. Unlike regular elements, pseudo-elements don’t represent actual HTML elements but provide a way to select and style certain parts of an element’s content or structure. They are denoted by a double colon (::) followed by the name of the pseudo-element.
Syntax:
\selector::pseudo-element {
property: value;

Common Pseudo Elements :
1: ::before and ::after:
These pseudo-elements allow you to insert content before or after the content of an element.
Example:
.example::before {
content: "Before ";
}2: ::first-line and ::first-letter:
::first-line targets the first line of a block-level element.
::first-letter targets the first letter of the first line.
Example:
p::first-line {
font-weight: bold;
}
p::first-letter {
font-size: 150%;
}3: ::selection:
Styles the portion of text that is selected by the user.
Example:
::selection {
background-color: #ffcc00;
color: #000;
}4: ::nth-child and ::nth-of-type:
These pseudo-elements allow you to select elements based on their position in a parent element.
Example:
li:nth-child(even) {
background-color: #f2f2f2;
}5: ::not:
Negates a selector, allowing you to select everything except the specified element.
Example:
p:not(.special) {
color: #333;
}
