How to Style Both Selected and Hovered Items with :after in CSS?

Combining :after with :hover in CSS

CSS offers a powerful combination of the :after pseudo-element and the :hover pseudo-class, allowing developers to create dynamic styling effects. This particular question revolves around applying the same styling to items when they are both selected and hovered over.

The provided code demonstrates a list of items, where the selected item (with the class "selected") displays an arrow shape using :after. The challenge lies in replicating this behavior for items being hovered.

The solution proposed in the response is to append :after to the #alertlist li:hover selector in the same way it is used with #alertlist li.selected. This ensures that the same styling is applied to both selected and hovered items.

Here's the updated code:

<code class="css">#alertlist li.selected:after, #alertlist li:hover:after {
    position:absolute;
    top: 0;
    right:-10px;
    bottom:0;

    border-top: 10px solid transparent;
    border-bottom: 10px solid transparent;
    border-left: 10px solid #303030;
    content: "";
}</code>

By implementing this change, the arrow shape will now appear not only for selected items but also for items that are being hovered over, providing a consistent visual cue to users.
