Hi ! Im tryin to make my collections lists smaller, i changed some css and made one of my collections lists smaller as well (but only affected to one called “Bajos”) the rest of collections lists didnt change at all. I dont know why, if someone can help me would be amazing! Thanks!

I just figured out its because the numbers of collections, if i have 4 blocks it works with the custom css, if i have more than 4 it doesnt work.
