Change Gallery Reel padding

Site URL: https://www.andreasbenckert.com/clei

I've had to alter the size of the Gallery-Reel, because I felt it was to large, even after setting it to minimum 30.

I ended up solving it by writing a custom CSS, which is:

.gallery-reel-wrapper {
      height:50%;
}

@media screen and (max-width:640px) {
      .gallery-reel-wrapper {
    height:100%;
}

Problem now is that I get 50% padding under the Gallery-Reel on larger screens.

Is there a cleaner way to writing the code or can I add another line to remove it?

Appreciate all the help 🙂
