How to make my woocommerce buttons' colors and font to change with the theme's

own customize area? whenever I change the color or font style, my woocommerce colors stay the same as per their default settings and wont change.

On my friend's website this salsa dance school, her buttons change with the theme's customize area, but mine dont. (She doesn't know how it was done)

I put links to my own website below and her website too. I am not sure what I am missing here. I used CSS a bit, but the buttons still look ugly.

My site is the Crypto one, and her site is the Salsa dance site. we both use GP Pro theme. thank you
