Changing background color on the logo area

Hi there!

How can i change the color in the logo area from orange to black and also the height.

Thanks

In layout.css:

.header {
height: 100px;
margin: 0 auto;
background: url(../images/header_bg.png) repeat-x;
}

change height and background properties

When i go on an other page apart from the Home page my background dont show up .. it shows the bg1.jpg but after its just blank why please and whows no other background

but on the home page i see all of the backgrounds

Use absolute path for that image in background property
