How to add background to header?

[visualtron]

Has anyone done this?

 

For my case, I've tried adding background to style.css, but without success:

 

#top{
background-color:#FDFEFF;
height:60px;
margin:0 auto;
padding:0;
text-align:left;
width:960px;
background-image: url(images/titanium.jpg);
background-repeat: repeat;
}
#top_container{
background-color:#FDFEFF;
border-bottom:3px solid #036;
color:#FDFEFF;
height:105px;
margin:0;
padding:0;
text-align:center;
background-image: url(images/titanium.jpg);
background-repeat: repeat;
}
