Firefox HTML problem - extra lines

I am having a problem using the FireFox browser.  IE works fine but when I view my website in firefox extra lines are added.  I think there is a compatibility issue with Styles but I am not sure how to correct.  Any suggestions?  

Here are my styles from CSS.

.bgmidbarshadow {
      
      background-image: url(http://vantagecard.com/images/bg_mid_bar_shadow.gif);
      background-repeat: no-repeat;
}

.blindtopwords {
      font-family: Verdana, Arial, Helvetica, sans-serif;
      color: #b3a46a;
      text-decoration: none;
}

}
.bgsideshadow {
      background-image: url(http://vantagecard.com/images/bg_side_shadow.gif);
      background-repeat: repeat-y;
      background-position: left;
      background-color: #FFFFFF;
}
.bgfootershadow {
      background-image: url(http://vantagecard.com/images/bg_footer_shadow.gif);
      background-repeat: no-repeat;
      background-position: top;
}
.bgmidgraphic {
      background-image: url(http://vantagecard.com/images/bg_mid_graphic.jpg);
      background-repeat: no-repeat;
      background-position: left top;
}
