After authors add options to have custom CSS files I made some quick file for demo. If you go under tools -> advanced -> custom css, enable it, after this go to tools -> (settings) load, browse CSS file and upload and voila.
Please note, this is customized with current markup, to achieve more "advanced" look and feel we need to update HTML markup. Also I have add quick options to enable mobile view

I hope you like it and that other members will post their customized css file
