Reduce padding on top and bottom of slideshow gallery in mobile

The padding on the top and bottom on gallery seems to be massive on mobile, especially the top. The navigation below ends up being far enough down as a result that you have to scroll to even see it. How can I reduce this? I have tried CSS to reduce the header bottom and gallery-slideshow top which maybe helped a little but not much. There was still a massive amount of padding

By default, the gallery page or section does not have the option to adjust padding. However, there is an alternative option available. If you start by selecting a blank page or section, you can then add a Gallery block to it, and the padding adjustment option will appear. It's important to note that there are design differences between the Gallery section and the Gallery block.
