I've made a slight change to the way the page loads custom css. Earlier, this css was loaded instead of the regular one, now it is loaded after the regular one. This means that any styling you enter will override the corresponding styling in the standard css, while leaving the rest. This gives a lot of flexibility in creating your personal style.
For example, the standard styling of the main background is:
body{background-color:#9DA963}
body{background-color:#335588}
.article_box{background-color:#9DA963}
.article{background-color:#9DA963}
.column_box{background-color:#9DA963}
body{
background: url(http://www.presskanne.com/kaffe_stor.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
