title: CSS: How to address specific tags
body: <p>I'm just beginning to learn CSS (and XHTML) and I ran into a problem of assigning different properties to tags which have the same tag name.</p>
  
  <p>For example: I have two h3 headers, but want to address them specifically using CSS because I want to make them different colours.</p>
  
  <p>I believe this has something to do with naming the headers differently (i.e. h3.a), but trying this didnt work. Help would be appreciated!</p>
