I made this as an alternative look for FA and I'm providing it free to use to all of FA.

This works in FireFox, Opera, Chrome, and Safari (via GreeseKit or manual switching, you're on your own there, sorry). Please make sure you have the latest versions of each to ensure it works, you can still try even if you're version is not up to date, but it may have some quirks I didn't account for.

Installing in FireFox
1. Get the add-on Stylish.
2. Go to here and save it somewhere for now.
3. Open it in notepad and select all, then copy.
4. Go Tools > Add-Ons > User Styles > Write New Style.
5. Name it as you please then paste what you copied into the main box and click save.

Installing in Opera (no round borders)
1. Download the raw style here and choose a folder where you'd like to keep it.
2. Go to the front page of FA and right click somewhere on the BG.
3. Go Edit Site Prefrences > Display > Choose.
4. Open the style-sheet from where you saved it.

Installing in Chrome
1. You must have the dev channel version of Chrome installed.
2. Get ChromeStylist.
3. Download the style sheet here and pick somewhere to keep it.
5. Open it in notepad, select all and copy it.
4. Go Wrench > Extgensions > ChromeStylist - Options > Add New Style.
5. In the first box give it a name, in the second put ^http://www\.furaffinity\.net and in the last paste what you copied and go to save.

IE does not support enough CSS3 for this to work with it.

To see the banner of the month just hover over the new logo. The logo is homage to  arsemaus as well as Conceptart.org

I hope you enjoy it. It does have a few quirks since I couldn't find what corresponded to what in the FA original style. So far I've found:

1. Hover boxes in the "Browse" section of the site are still the original colors.
2. Selected items in the Messages area are still the original colors.

If you find how to solve this or find any other quirks please let me know. Also feel free to use this as a template to make your own styles as you see fit.

Enjoy!

P.S. For a simplified version you can check out: http://pastebin.com/f4611aa66 which was put together from my original simple version by  freehaven . I won't be trouble shooting this version and you're on your own for setup though.

*Edited for smarted handling of font styles.

*Fixed the hover box colors for the browse section of the site.

Installing in FireFox 2.5 (Mac)
1. Get the add-on Stylish.
2. Go to here and save it somewhere for now.
3. Open it in notepad and select all, then copy.
4. Go Tools > Add-Ons > User Styles > Write New Style.
5. Name it as you please then paste what you copied into the main box and click save.

(If you find quirks in this one send me a screenshot)
