How Can I Apply :hover and :visited Styles to `a:before` and `a:after` Pseudo-elements?

Implementing Hover and Visited Conditions for 'a:before' and 'a:after'

When seeking to apply :hover or :visited conditions to pseudo-elements like 'a:before', syntax can become an obstacle. Understanding the proper syntax and element hierarchy is crucial.

Syntax for Pseudo-Elements and Pseudo-Classes

For pseudo-classes to affect pseudo-elements, they must follow this order: a:hover:before, a:hover::before, or a:visited:before, a:visited::before. In this structure, the pseudo-element is appended to the end of the selector. This is emphasized in the CSS specification, which defines pseudo-elements as separate entities from simple selectors.

User-Interaction Pseudo-Classes and Pseudo-Elements

However, when it comes to user-action pseudo-classes like :hover, applying the effect only to user interactions with the pseudo-element and not the 'a' element itself poses challenges. CSS pseudo-elements do not currently support pseudo-classes.

To achieve this effect, consider using an actual child element with :hover instead of a pseudo-element. By understanding these nuances, developers can effectively apply hover and visited conditions to pseudo-elements.
