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.
Is there a default margin or padding on the left side?
<h3>Title Heading</h3>
   <ul id="listItems">
       <li>itemOne</li>
       <li>itemTwo</li>
       <li>itemThree</li>
   </ul>
The main body has all the css code for centering, aligning, float, etc. The 'Title Header' align perfectly. Just list is a little off.
Thank you.
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).
