I have a CSS entry that looks like this:
.header {
    background-image: url("./images/embouchure.jpg");
    background-repeat: no-repeat;
    height:160px;
    padding-left:280px;
    padding-top:50px;
    width:470px;
    color: #eaeaea;
    border-bottom:1px solid #eaeaea;
}
How can I add the link to the the background image in that CSS?
The full CSS can be found here and the html that uses is there.
