Pseudo-element (CSS)

In Cascading Style Sheets, pseudo-elements are style rules that affect certain parts of a web page.

Description

Pseudo-elements are added to the browser's Document Object Model (DOM).

Pseudo-elements really are elements in the web page, because the DOM is the browser's internal representation of all the CSS rules it has processed.

Example

• Style the first letter, or line, of an element
• Insert content before, or after, the content of an element
