On my site, the number of an ordered list item will disappear when the list begins with a blockquote. This problem occurs in IE 7, but not Firefox or Safari. Here's an example: http://arborupdate.com/article/1843/primary-results-coming-in#c025109 Any ideas what might be causing the problem? Than

[css-d] Why do paragraphs expand to hold floated images in IE 7?

I was testing this page in IE 7: http://www.rc.lsa.umich.edu/forum/urban.htm and instead of the two paragraphs wrapping around the photo, the first paragraph expanded to contain it, pushing the second paragraph below the photo. The page works correctly in the latest versions of Firefox and Safari

[css-d] No floating in Safari, no flowing in IE 7

I have two problems that I think are related: 1) In Safari, images refuse to float. For example: http://arborwiki.org/city/Jiffy_Mix. The photo floats right in IE and FF. The CSS is at http://arborwiki.org/skins/styles.css 2) In IE 7, the images float, but paragraph text doesn't flow around them.
