Browser Support for the :has() Pseudo-Class
The :has() pseudo-class is powerful but its browser support varies. Modern browsers have started supporting it, but older browsers and some versions may not recognize it yet.
Fully supported in the latest versions of Chrome, Edge, Safari, and Opera.
Firefox started supporting it experimentally in newer versions, but it may require enabling a flag or be limited in some releases.
Internet Explorer and very old browser versions do not support
:has().Always test critical use cases and provide fallbacks or progressive enhancement for unsupported browsers.
Because :has() can affect styling dynamically based on child elements, you may want to use feature queries (@supports) or fallback styles to ensure a good user experience in browsers that do not support it.
Check browser compatibility before using
:has()in production projects.Use feature queries (
@supports) to apply styles only when supported.Consider progressive enhancement so that the UI works even without
:has().Test on multiple browsers to ensure consistent appearance and functionality.
