Is this possible? Does it have to be a certain amount of pixels?
Are you pertaining to the background image? If so:
Unfortunately, there’s only 2 things you can do.
Assuming you want to keep the background-size to cover, it’s either you set the padding top and bottom or you set the min-height or height.
The idea behind setting height is basically to make the container large enough to give more vertical viewable space to the container element for its background image.
Adding padding does the same thing but instead of dealing with height directly, you add height through adding padding top and bottom values.
