title: body height 100% bigger than screen height
body: <p>I've set my <code>html body</code> tag heigth to be <code>100%</code> but in Firefox that shows as a few more pixels than the screen has, so a nav scroll bar appears. How can I adjust that other than specifiying an arbitrary <code>height :98%</code>? I've set <code>padding</code> and <code>margin</code> to zero.</p>
  
  <p>I'm using only bootstrap for css, if that's of any importance.</p>
