<p>Well there is alot of things you can do to chat. I'll list a few:
</p>
.ChatWindow {
background: ''color'' url(''url of image goes here'');
background-color: ''color'';
background-image: url(''url of image goes here);
background-position: left top|left center|left bottom|right top|right center|right bottom|center top|center center|center bottom|''x''% ''y''%|''x''px ''y''px|initial|inherit;
background-size: auto|''x''px ''y''px|''x''% ''y''%|cover|contain|initial|inherit;
background-repeat: repeat|repeat-x|repeat-y|no-repeat|initial|inherit;
color: ''color'';
}
.ChatWindow #WikiaPage {
background: ''color'' url(''url of image goes here'');
background-color: ''color'';
background-image: url(''url of image goes here);
background-position: left top|left center|left bottom|right top|right center|right bottom|center top|center center|center bottom|''x''% ''y''%|''x''px ''y''px|initial|inherit;
background-size: auto|''x''px ''y''px|''x''% ''y''%|cover|contain|initial|inherit;
background-repeat: repeat|repeat-x|repeat-y|no-repeat|initial|inherit;
color: ''color'';
}
<p>
Yeah they have basically the same properties but you can set them to have different values (<i>note that the | means "or"), and not all properties (background, background-color, background-repeat, etc.) must be used.</i>
