Wildcards In CSS [blog]

This article discusses the concept of wildcard selectors for HTML elements in CSS, such as `mdn-*` to match all custom elements starting with a prefix. It compares current workarounds using attribute selectors like `[class^="btn-"]` and `[class*="btn"]`, noting their limitations and brittleness. The author proposes adding native wildcard support to `querySelectorAll` for cleaner web component initialization, referencing Lea Verou's earlier proposal. The article also touches on parser constraints and the potential for glob-like patterns. It is relevant to web development, CSS, and front-end technology.
