For so long as builders have written CSS code, we have been determined to have a way to permit styling a father or mother ingredient primarily based baby traits. That is not been doable till now. CSS has launched the :has pseudo-class which permits styling a father or mother primarily based on a relative CSS selector!
Let’s take a look at a number of use instances for :has in CSS:
/*
If an `a` ingredient incorporates a picture, set the `a`'s show
*/
a:has(img) {
show: block;
}
/*
If a `determine` has a `caption` with a `multiline` class
permit the `determine` to have any peak
*/
determine {
peak: 200px;
}
determine:has(caption.multiline) {
peak: auto;
}
/*
Cover an advert containing `div` till advertisements load
and have been injected
*/
.ad-container {
show: none;
}
.ad-container:has(.advert) {
show: block;
}
/*
If we've got an `article` ingredient with no heading,
add high padding as a result of `H1`s have high padding
*/
article:not(:has(h1)) {
padding-top: 20px;
}
