Hi Tuanphan, this code worked for me, but it is giving me trouble for sections where I use an inset section background. 
Here is an example:
I'd like to reduce the white space between these two color blocks (pictured below).
However, when I use the code you provided, it reduces the padding between the content within the color blocks and the top/bottom edge of the color block, but it does not reduce the white space between the two color blocks (see second screenshot, below). 

I'd like to keep the padding between the content within the color blocks and the top/bottom edge of the color blocks, and only reduce the white space between the color blocks. Could you help with this?
Thank you!
