Pseudo Elements

Pseudo Elements are used in CSS to add stylised content to a webpage. They allow designers to add specific styles to only certain parts of an element, such as the first letter of a paragraph or the background of a selected text block. Pseudo elements are created using double colons and target specific parts of an element through selectors used in the CSS code. This feature enhances the usability of a webpage and gives developers more flexibility and control over the appearance of their designs.
