Although we can't quite see what would be a use case for a tabbed content where there are tabs and none of them are active (for example, it's weird to think of a browser where we have a bunch of tabs open and none of them are active...), we decided we'd let that possibility exist in code: the reactive `.active` can be set to the empty string both on `Tabs` and on `TabbedContent`.
Sorry but I spotted that the syntax highlighting was wrong in my last PR to
add tcss to the docs (#4171) where I had blindly copy pasted the code.
A quick grep found a few other places in the docs where the syntax
highlighting was wrong. This PR corrects the language to css.
