How to center everything on Offline Page

Please help me to Center everything on Offline page. Look at pic

Hi,
you can edit this file: gk_msocial\offline.php
very easy if you know basic of HTML.

p.s.
But I suggest to use this : http://extensions.joomla.org/extensions ... line/18971

much better than offline mode.
or
you can use: http://tools.dynamicdrive.com/password/

Thank u Pawel, but this extension is just for J!2.5. I m on J!3.1

This main joomla Offline page is needed because a Client need access to see work process.

I've added float: center on all div's but header is still left oriented. (offline.style1.css)

ok, but you did not mention about this.

I sympathizes with you, there is nothing worse than a customer who complains when you're doing something.

Hmm, do you know CSS well ?

Values for float are : left, right, none and inherit. I didn't hear about center for it!

You can use text-align:center; or/and margin:0 auto;
