Im using the context theme and cant seem to figure out how to remove the padding around my logo. I cant find a header.liquid in sections or .css file in assets as the other answers point to.
There are no paddings around the picture. The fact is that the image itself has extra space. It is better to cut down and leave only the logo itself. Then there will be no such large margins.
Thank you for the help @Anonymous , It must of been a silly mistake. However I do still have a small amount of margin/padding at the top of the logo with that fix.
