How to adjust mobile collections page without affecting desktop view?

So i have created a collections page, and on desktop it is perfect and centered, but when i go on my phone the collections are off center and too small. How do i fix this without changing the look of my website on desktop? I have previously posted to find a solution but couldn’t find one, so any help would be much appreciated.
