Thread:Project:Support desk/Reduce logo size with css

MediaWiki v1.18 PHP v5.2.5 MySQL v5.0.91

For the site logo, I'm trying to do something similar to the HTML trick to increase image resolution by using a larger image then reducing how it's displayed using height/width in the code. The larger image thus reduced shows far more detail then the option of placing a logo of the exact size that is displayed. I've tried various code in common.css to reduce a logo about twice the 135px/135px, but it never works. Instead the larger image slides off the page instead of being reduced.
