→ Efficiently Rendering CSS
So we know that ID’s are the most efficient selectors. If you wanted to make the most efficiently rendering page possible, you would literally give every single element on the page a unique ID, then apply styling with single ID selectors. That would be super fast, and also super ridiculous. It would probably be extremely non-semantic and extremely difficult to maintain. You don’t see this approach even on hardcore performance based sites. I think the lesson here is not to sacrifice semantics or maintainability for efficient CSS.
Good to know.
