123456# CSS Best Practices78## Selectors910- Avoid `:has()` selectors. Because their result depends on descendant state, DOM mutations can invalidate styles on ancestors and cause expensive style recalculation, especially when selectors are broadly scoped. Instead, represent the state explicitly with a class or data attribute on the smallest container you own, and scope selectors to that marker. Add and remove the marker together with the state it represents.11
One repository carrying more than one format is the comparison this product exists for: does anyone actually write different content in each file, or is one a copy of the other?

A badge carrying the measured quality of the strongest agent config file in this repository, out of 100. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.
