Background vs Font issue w/ div tags

hey guys,
i have a website were i am looking at getting the background to have a 35% opacity while keeping the copy inside of it at 100% opacity. heres the basic part of my script:


body {
font-family: Verdana, Arial, Helvetica, sans-serif;
color: #FFFFFF;
padding: 0;
margin: 0;
background: url(../images/back1.jpg) no-repeat center top;
}

#content2 {
width: 876px;
height: 600px;
margin: 0 auto;
padding: 15px;
background-color:transparent;
background-color: #000000;
opacity:0.35;
-moz-opacity:0.35;
filter:alpha(opacity=35);


seems like it would be a simple solution but not simple enough for me. any suggestions/ideas/solutions? anything would be great. thanks in advance!
