More margin/padding options

Something I would improve would be to allow more freedom on padding controls. Vertical padding controls both top and bottom padding equally. But sometimes I just want to adjust the top or bottom separately. Same goes for horizontally.

I've also noticed that on responsive view for mobile if a value is not placed in the horizontal padding element the text will render a very slender text area on mobile view when it is life. If you want no horizontal padding and enter 0 as the value and then later make any other changes, the 0 value is lost and the text renders narrow in live mobile view.
