Using Pseudo-element Selectors.
CSS pseudo-element selectors allow you to apply styles to specific parts of an element. They are useful for improving the presentation of elements without needing to modify the HTML.
Syntax
The basic syntax for using pseudo-elements in CSS is:selector::pseudo-element { property: value; }
Some examples of pseudo-elements are:
::before: Inserts content before an element's content.::after: Inserts content after an element's content.::first-letter: Applies style to the first letter of a block of text.::first-line: Applies style to the first line of a block of text.::selection: Applies style to the selected portion of the content.
Purpose
Pseudo-element selectors allow you to:
- Style the first letter of an element.
- Add content before or after an element.
- Style the user's text selection.
