Summary block "breaking"

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

Hi, my summary block (on the homepage) has 3 images and it keeps adjusting to the size of the browser, making it into two rows. I'd like to keep it locked as one row for desktop regardless of the browser's size, but not for mobile, which I'd like to keep as it is now, one image stacked on top of another. Thanks in advance for any help!

Hi. You want 3 images/row on all devices?

@tuanphan thanks for replying. i'd like 3 images on a row for desktop, not for mobile.
