I've only seen one Yahoo! user login of this recent layout on userstyles.org so far by JaaC1. All I did was edit the original CSS background URL. I thought I'd blend the top and bottom white borders into a background and give it more of a flow into the white. It isn't perfect but it looks nice.
A dark style for yahoo answers.

A dark theme featuring classic Yahoo! purple to compliment cool shades of blue and grey. This style works with most Yahoo! domains. I tried to keep this simple and fast, so no replacement images or base64 are in this script. ***UPDATE!*** I found this script also works with The Huffington Post. It isn't seamless, but the layout is similar enough that I really like how this works. If you prefer to keep your old install of Yahoo! Cool Dark Purp, just add [domain("huffingtonpost.com"),] to the list below @-moz-document.
Compacted Yahoo header, simply to leave things just for mail, along with removed ads and apps. Hidden Ads, Top-bar changed into a pop-down Top Bar on mouse over, and generally made more room for the e-mails while removing some extras. Works with all Themes, so feel free to choose any.
