The problem page is here: http://kihre.com/portfolio/ibuenacasa/, the css directory is here http://kihre.com/portfolio/ibuenacasa/css
Everything validates, and in IE it appears as it should, but in Firefox everything lines up vertically instead of floating correctly. All my syntax appears to be proper, and I've checked all my semi-colons and brackets.. so at this point I simply dont understand where I've gone wrong. This is my first time really working with floats, so I suspect it's improper usage or something of that nature, or quite possibly some dumb mistake I can't seem to find on my own.
Thanks in advance for any help!
