title: Does UL have default margin or padding
body: <p>This might seem like a dumb question, but I've added an UL to a basic page and the list seems to be off-centered.  There's nothing special about the list.  No specific css added: just a list.  When I load live it's slightly off center.<br>
  Is there a default margin or padding on the left side?</p>
  
  <pre><code>&lt;h3&gt;Title Heading&lt;/h3&gt;
     &lt;ul id="listItems"&gt;
         &lt;li&gt;itemOne&lt;/li&gt;
         &lt;li&gt;itemTwo&lt;/li&gt;
         &lt;li&gt;itemThree&lt;/li&gt;
     &lt;/ul&gt;
  </code></pre>
  
  <p>The main body has all the css code for centering, aligning, float, etc.   The 
  'Title Header' align perfectly.  Just list is a little off.</p>
  
  <p>Thank you.</p>
  
  <p>Oh, don't know if this is important, but I added the 'id' cause... wanted to use 'first-of-type' to give 1st item em(bold).</p>
