Create custom responsive cPanel-design based on x4 and x4mail

Build a branded cPanel theme based on x4 and x4mail to our colors and look & feel. It needs to be responsive. We will provide you with our own look and feel in which environment this cPanel will be used. We do need to have it in three different versions but with only a very slight variation: 1) One that would be "full" cPanel (all regular features), 2) One in which we could take away the features we may not want to show our customers, they include locale-changing, theme-changing, cron jobs and all database access (incl PHPMyAdmin etc). 3) One in which the hidden features would be greyed-out, such that clicking them will take the user to an upgrade page. Our general requirements are: General requirements: - No frameworks except jQuery are allowed. - All styles should be in separate CSS-files. Inline CSS is a big no-no! - The code should be neatly indented and well commented - Names of variables and functions need to be clear and understandable - Use tooltips based on jQuery cluetip where appropriate. Clarification is always a good thing.
