CSS ::before and ::after pseudo-elements allow you to insert “content” before and after any non-replaced element (e.g. they work on a
but not an ). This effectively allows you to show something on a web page that might not be present in the HTML content. You shouldn’t use it for actual ..

Shadow Roots and Inheritance

There is a helluva gotcha with styling a
element, as documented here by Kitty Guiraudel. It’s obscure enough that you might never run into it, but if you do, I could see it being very confusing (it would confuse me, at least). Perhaps you’re aware of the shadow DOM? It’s talked about a lo..
