Removing Background

Hi all!

Is there a way to remove the default chat background with CSS?

Code:

body.chatbox {
  background-image: url('http://oi58.tinypic.com/1ooh03.jpg');
  background-color: black;}

I used this code, but the bacground overwrite it.

And is there a way to wiew the chat in new window mode?

When overwriting anything you must use the !important modifier (I guess you can call it. LG will correct me if I am wrong)

Code:

[panda=css]body.chatbox {
  background-image: url('http://oi58.tinypic.com/1ooh03.jpg')!important;
  background-color: black!important;
}
<!--Though it's important to say you can save space by shorthanding this-->
body.chatbox {
  background:#000 url('http://oi58.tinypic.com/1ooh03.jpg')!important;
}
