The Undeniable Utility Of CSS :has * Josh W. Comeau
Briefly

The :has pseudo-class allows developers to style a parent element based on the children it contains, shifting the conventional top-down styling approach in CSS.
After experimenting with the :has pseudo-class, I found it to be an incredibly handy utility, especially in scenarios involving dynamic components and state management.
Even for JavaScript developers using React, Vue, or Angular, the :has selector offers new possibilities for styling components responsively based on their internal content.
This blog post aims to illustrate the usefulness of the :has pseudo-class through real-world examples and practical applications that enhance CSS usability.
