How to center 'Add to cart' and Variant buttons in Shop section?

Hi!

I'm struggling to align the 'Add to cart' buttons and the 'Select Time' variant so that they are centralised under the product items in the shop section.

Would appreciate some help with this. I would like the images, text and buttons to be center aligned on mobile as well.

Can you set the store to 2 columns instead of 3? Are you using code to try and move these elements?

Even when it's set to 2 columns it has the same issue unfortunately.

I've only used code to edit the style, not to move any of the elements. 

It looks like there's something broken, have you tried removing all of the code you've added?

You can try viewing in safe mode by adding /safe to the end of your URL when editing the website to try and determine if the problem  is with your code.
