Added some css to beautify kelasiTline view

Dear Sadegh,

I added some CSS to kelasiTline to beautify its view. I also going to add some other style sheet and right to left direction mode for harmonizing Persian fonts.

I send this pull request but I'm not sure whether it is okay to send you pull request every time I change the kelasiTline or not. Tell me what do you think about our pull request policy.

have fun,
Saeed
