@man4toman Done! Thank you!

I create #19 for this issue.

But there is some questions like, where can I find the font sizes, padding and margins from designs?
Should we stay loyal to the size? Or should we work according to the current codes and the intervals defined in the original style.css file?

@iamchetanp can you answer these questions?
