Interact with the :before pseudo element when hovering over an element

Is there a way to manipulate the :before pseudo element when hovering over the main element?

My goal is for the pseudo element to change its height when I hover over the main element.

This is how my code looks:

HTML

<div class="object"></div>

CSS

.object:hover object:before {
  height: 30px;
}

Answer №1

To customize the appearance of the hovered before pseudo-element, you can apply CSS styles for both normal and hover states using a selector like .object:before:hover {}.

Here is an illustration showcasing this concept:

.object:before {
  content: " ";
  width: 30px;
  background-color: red;
  display: inline-block;
}

.object:hover:before {
  height: 30px;
}
<div class="object">
Hover Before Example
</div>

Answer №2

To achieve the desired effect, use the object:hover:before selector. Here is an example:

.object {
  width: 50px;
  height: 50px;
  background: blue;
}

.object:before {
  content: "HOVER";
  background: green;
  height: 3px;
}

.object:hover:before {
  display: block;
  height: 100px;
  background: red;
}
<div class="object"></div>
