Remove blank space on mobile version of homepage

Site URL: https://leslilasfrenchschool.squarespace.com

On my homepage's mobile version I have extra blank space before and after my gallery section. I'm using version 7.1. Is there any way to remedy this?

Thank you!

I'm not sure if the mobile editor works the same as desktop but I had the same problem. Try editing the homepage, scroll down to the space where it is blank and move your cursor around to see if there are any padding or text fields that highlight when you scroll over them. If they pop up, you can remove them with the little red trash can. If none pop up, try using the page editor and trying the different section height settings. Hope this helps.

Thanks. I've tried all of that, but still can't get rid of the blank space on the mobile version. 😞

Add to Home > Design > Custom CSS

@media screen and (max-width:767px) {
.homepage .gallery-slideshow {
    margin-bottom: 0 !important;
    height: 40vh !important;
}
}

Thank you Tuan! That worked!
