CSS Worksheet: Selectors Class and Id

HTML and CSS lesson 13: Selectors: element, class and id · Set 67 · 40 questions

Code tip (Dot for class, hash for id): p matches every <p>; .note matches class="note"; #top matches id="top". A dot means class, a hash means id — mixing them up matches nothing. Many elements can share a class; an id belongs to only one element.
