Question

Please can you tell me why the dark blue background (between the main white section and the outer light-blue section) not show in FireFox? It does show in IE.

The site URL is http://www.moorespeed.co.uk/

The relevant code is at: http://www.moorespeed.co.uk/Content/site.css

#page 
{
    background-color:#082d47;
    margin-left: auto;
    margin-right: auto;
    padding: 0 0 0 0;
    width: 970px;
}

Answer 1

Your #main div is floated, and a container doesn’t automatically expand to contain floated children. However, if you apply overflow:auto to #page, it should expand like you were expecting:

#page 
{
  background-color:#082d47;
  margin-left: auto;
  margin-right: auto;
  padding: 0 0 0 0;
  width: 970px;
  overflow:auto;
}
