What students do

Six clubs and businesses have style sheets that don't work. Students fix each page's CSS or its link tag, and watch one rule style every tag it names.

What it adds to the lesson

The paper version of One Rule, Many Places has four pages. Here one fixed rule restyles the page as students type, so they see how far a single rule reaches.
