How would I change the Input styling on my forum
http://clandev.net/forums/

More specifically,

<input id="login" type="text" name="quick_username" size="8" title="Username" class="textbox" value="Username" onfocus="this.value=''" tabindex="1">

<input id="login" type="password" name="quick_password" size="8" title="Password:" value="Password:" class="textbox" onfocus="this.value=''" tabindex="2">

Also made this, but not sure how good it is...

I made the ID's login, and I've tried to style it, it just never works right.
Also if any of you are using firefox, does the forum look messed up?
It does in my firefox, and it wont update any CSS attributes even after i clear the cache. Yet it looks perfect in chrome.

No one can help out?
Not sure if I'm aloud to bump or not, but it's been almost 2 days...

Error on the image.

Woah I don't know how it got deleted, but its just a rounded off rectangle... I can deal with the image, I just can't figure out why it wont change the boxes
