Theme is the first version,Please tell me the mistakes or everything you think should fixed or added ( You can mail me for that. Mail Me. ) - I will update this theme later too - And you can download the theme from the bellow Links:

Download normal version
Download online loader version ( For poor servers )
I will add a new version later - That imports style sheet files from some CDNs and the size is really smaller.
Please participate in the poll too.
Online Loader Version ( For poor servers ) Loads all stylesheets and JavaScript files online, That means users' requests doesn't apply on your server, Rather it sends to 20Script servers.

Update: Oxygen OPT ( Online Loader ) link added.
Update: To use theme for Right To Left languages ( Like Persian and Arabic ) add the bellow code in the last line of Oxygen.min.css

html body * {direction: rtl !important;}
