No more excuses: Now we can target the parent element with the child in CSS.

In the ever-evolving world of web development, CSS continues to be a powerful tool for creating visually appealing and responsive websites. One common challenge developers often encounter is trying to style a parent element based on its child elements. Traditionally, this task required the use of JavaScript or complex workarounds. We’ll explore how this technique eliminates excuses and empowers developers to target parent elements using only CSS effortlessly.

The Challenge: Targeting Parents Based on Children

Imagine a scenario where you only want to style a specific container if it contains a certain child element. For instance, you might want to apply a distinct border to a parent <div> only if it contains an <h1> element. In the past, achieving this required adding additional classes or resorting to JavaScript. With the introduction of the :has pseudo-class, this task becomes much more straightforward.

Introducing the :has Pseudo-class:

The :has pseudo-class is a new addition to CSS that enables us to select an element if it contains a specific child element. This is a major leap forward in terms of simplifying selectors and improving the maintainability of stylesheets. Let’s dive into an example to see how it works:
