Hi Tahir,

I feel like I found a CSS bug.

In the two screen shots, I am showing you a row, with 3 columns. 

1/6 + 4/6 + 1/6

On desktop view, it looks fine, but on mobile or tablet portrait view, the columns do not span full width.

I can confirm it is a column issue because if I change column sizes to

1/4 + 1/2+ 1/4

the symptom is not there.
