How to Style an Arrow Indicator for Selected and Hovered List Items?

Styling an Arrow Indicator with Combined :after and :hover

You aim to combine :after with :hover to create an arrow indication for a list item. When an item is selected or hovered over, this arrow should appear.

In your provided code, you've correctly styled the arrow indicator for selected items using :after. To apply the same styling to hovered items, simply append :after to the :hover selector.

Here's the updated CSS:

<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>

This modified code ensures that the arrow indicator is displayed both for selected and hovered list items, as intended.
