Can you link to where you are trying out the link CSS? It looks like the CSS is all you should need.

As for the thread posts, yes, it could be done with JS because JS is not limited to the single-pass that CSS is. CSS is applied in a single, linear pass over the HTML; that is why you cannot select parent or predecessor elements.
