How can I resize the variant picker in the Dawn theme?

[ecom33]

Hello!

I wish to resize the variant picker on the product page. What code do I need to add to make those icons smaller?:

Is there a similar way as it is with Add To Cart button, where to edit it I just need to paste the code like below to the bottom of base.css:

Thank you for help.
