Add a CSS style to an element when its parent container is hovered using Angular

Question

Add a CSS style to an element when its parent container is hovered using Angular

I am looking for a way to change the appearance of an element when its container is hovered over using CSS or SCSS.

Here are my requirements: - The solution must be implemented within the child component or the sass file, without knowledge of parent-child relationships. - Can use either SCSS, CSS, or Angular component code.

I have already experimented with the host listener decorator in Angular, but it only targets the host element itself, not its parent.

I also tried using the :host and :host-context selectors, but ran into similar issues as with host listener.

Any suggestions on how to achieve this would be greatly appreciated.

EDIT: To better illustrate what I'm trying to accomplish, imagine a small square inside a larger square. When hovering over the area outside the small square but still inside the large square, the small square should change style.

Answer №1

To add a small square in your HTML code, remember to enclose it with a div tag:

<div class="small-square">
  // include the rest of your HTML content here
</div>

For styling your small square using CSS, you can use the following code snippet:

.small-square:hover {
  // add your desired styles for hover effect here
}

If you are unable to implement the above solution, you may consider adding the styles in your global stylesheet (styles.css) like this:

.large-square:hover .small-square {
  // define styles for the small square when the large square is hovered over
}

Alternatively, you can try utilizing host context in your CSS code as shown below:

:host-context(.large-square:hover) .small-square {
  // apply styles to the small square when the large square is hovered over
}

:host-context(*:hover) .small-square {
  // specify styles for the small square when any element is being hovered over
}

If the above methods do not work, your last resort would be to incorporate the styles in a global stylesheet.
