Hello Fellow Coders! 👋

Ever found yourself scratching your head over styling parent elements based on their child's class? Fear not, for here's a CSS trick that might just blow your mind!

The Solution:

Introducing :has() CSS pseudo-class a game-changer method to achieve the parent element appearance based on the child element.

Quick Explanation:

The :has() is a pseudo-class CSS that takes a selector as an argument. On your parent element add :has() pseudo-class CSS to target the element that matches the passed-in argument.

For Example:

Consider a simple small Card Box.

<div class="card">
    <h2>Hello World!</h2>
</div>

Now you want to change the card appearance like adding a box-shadow. when child div has active class.

box-shadow: rgba(149, 157, 165, 0.2) 0px 8px 24px;

How can you do this? 🤷‍♂️

You can add like this:

.card:has(h2.active) {
   box-shadow: rgba(149, 157, 165, 0.2) 0px 8px 24px;
}

Alternatively, You can achieve this using JavaScript to add or remove classes from the parent div based on the state of the child div. However, there is no need for JavaScript – just pure CSS magic! 🤩

Happy coding! 💻✨
