All of the following CSS will go in your wiki's MediaWiki:Wikia.css to customize the chat for all users or Special:MyPage/wikia.css on your local wiki to customize the chat just for yourself.

1. Changing the background: 2. Changing the star icon: 3. Making the text window translucent: 4. Use this. However, do note that this will affect all the text of the same format. Since you have not asked already, do you want to customize the header and the wordmark on the rail too (as seen in the image)?
