The above pic is not having the same margin-top on mobiles. It seems fine on larger screens
The code is here http://codepen.io/hungnguyen1895/pen/rrOyLL
Do you mean the margin below “Send” button? I would just add margin-top: 1% to the .quote class to fix it
I mean the content in the green box. All I uses is cols
Perhaps I’m not nearly as proficient with code as most, but in resizing your page, I’m noticing that your columns (images therein) are slightly off kilter. In regards to columns they are set to a 12 col rule (one that can be broken if you are intending to do something creative with your responsive page), otherwise, everything in each row should equal 12. https://getbootstrap.com/examples/grid/
I hope this helps somewhat. Again, I could be completely out of my depth. I struggled with the grid/col system.
