I'm trying to theme my basic app - I'm looking to customise a few aspects mainly through additional DIV's using ID's and Classes, but I also want to change a few other bits.

For example I cannot get the background color to change. See below for my CSS:

.ui-page { 

    font-family: 'Museo', verdana, serif;

    background-color: #2b2e31;

}

 The font has changed but the background color isn't flowing through. Any suggestions?

Thanks
