Remove padding, top edge of block to image

Hi guys,

There's a bar of white space from the top edge of the block to the image itself (plz see screenshot), I really want to remove it but I don't know how.   I'm assuming it'll need custom CSS codes.  Can someone please help me? 

Thanks!

Add to Home > Design > Custom CSS

#page section .content-wrapper {
	padding-top: 0 !important;
	padding-bottom: 0 !important;
}

Thanks Tuanphan, it worked!
