Login form styling

[d'Hinnisdaël]

Does anybody else feel like the login screen could use a revamp? While it might not be the most important thing in the world, first impressions count.

On large(r) screens the login form seems to get lost in the upper third. The rest of the admin looks a lot cleaner and more deliberate.

A few tweaks would go a long way in making the login screen work on all device sizes. Those are two custom styles I've been adding to my sites lately, one PW-branded and one not. No markup changes needed, just CSS.

This second one borrows heavily from Twill's login screen.

The floating environment label has turned out to be really useful to see at a glance if one is editing on staging or live. Not sure if there's a way to make this 100% core compatible.
