title: Targeting multiple elements with one class
body: <p>I have the following code:</p>
  
  <pre><code>#bottom p, h3 {
        color: red;
  }
  </code></pre>
  
  <p>I just want to make the h3 in the div with class #bottom to be red.  But all my h3 tags are now red across the page.  As this h3 tag is preceeded by the #bottom id should it not just be the h3 tags within this div that change to color red?</p>
  
  <p>Interestingly I have other <code>&lt;p&gt;</code> tags in my html and a css code for those <code>&lt;p&gt;</code> tags of color white and they are not turned red.</p>
