Troubleshooting Wikipedia's look and feel with skins
Wikipedia should work in any web browser. However, depending on the layout of an individual page and the skin set in your user preferences, a page layout might be broken in your browser. If the problem occurs on a single page, edit the page to fix it yourself. If you can't fix it, put a message on the talk page (a screenshot always helps!). If the problem occurs on all pages, try a different skin. "Nostalgia" should work even in ancient browsers. Your browser might have some minor issues. These are listed at Wikipedia:Browser notes.
