has

has in css

The functional :has() CSS pseudo-class represents an element if any of the relative selectors that are passed as an argument match at least one element when anchored against this element. This pseudo-class presents a way of selecting a parent element or a previous sibling element with respect to a reference element by taking a relative selector list as an argument.

CSS 函数式伪类 :has() 表示一个元素，如果作为参数传递的任何相对选择器在锚定到该元素时，至少匹配一个元素。这个伪类通过把可容错相对选择器列表作为参数，提供了一种针对引用元素选择父元素或者先前的兄弟元素的方法。
