Thread:Project:Support desk/Text-based logo

Version information:

MediaWiki	1.23.6 PHP	5.4.16 (apache2handler) MariaDB	5.5.41-MariaDB

Wiki is hosted internally and not accessible from the WWW.

Question:

Can a text-based logo be used, and dressed up with CSS inside a div tag, or does MediaWiki require an image-based logo?

Thanks
