shrinking slideshow gallery size

Site URL: https://www.redwoodlandscapes.com.au/projects

Hi, I'm trying to reduce the image size of the galleries so you can see the full image and the thumbnails on the screen - currently only works when you zoom out on the website, thank you!

Try adding this to Design > Custom CSS

body#collection-62ee45e6010ae8217b942708 .gallery-block {
    transform: Scale(0.7);
}
