float #login_error

Just a quick question – I am hacking about the wp-login.php?action=register page to make it fit with the site theme, and need to position the #login_error in a specific place. All is fine except it doesn’t float – whatever the css – it stays in place and pushes the form below down. Is there a reason this happens? It’s driving me insane!

My css is:

#login_error {width:947px; background-color:#9a0000; color:#fff; font-family:"Century Gothic", Arial, Helvetica, sans-serif; text-transform:uppercase; color:#ccc; font-size:.8em; float:left; margin-left:5px; margin-top:16px; padding:2px }

Any ideas? Cheers!
