Wiki Patch

Hi! In the kindofblue theme, the sidebar is absolutely positioned, which makes it overlap/cover the footer on short pages (e.g. http://fedoraproject.org/wiki/Websites/Join?action=info). I've made a quick patch to switch to a float-based layout and avoid this problem. The patch also replaces "sidebar-header" (purely presentational markup) with a background-image on #header (this required me to alter wiki-sidebar-header.png slightly). I've put the relevant files up here: http://fedoraproject.org/wiki/RickyZhou/kindofblue Side note: I just joined this group yesterday, so please let me know if there are any tasks that I can look at/get involved in. Thanks, Ricky
