As you can see, the DBA community site got a slight design update today. We have moved the site's CSS to a newly refactored LESS system, so it's easier for us to fix SE network CSS bugs globally in the future. Also we've updated the graphics to SVG for retina support. Visually it should "feel" the same as the old site with slight layout adjustments.
This update should retro-actively fix most of the old CSS bugs. If you see any new ones, or old ones not being fixed, please let us know!
