Hello, @Rivka,
You can set the font size of these things from the theme settings.
1- Simply navigate to the Dashboard >> XSTORE >> Theme Settings >> WooCommerce >> Single Product Builder >> Short Description >> see image: https://postimg.cc/LhRxsMgY
2- Simply go to the Dashboard >> XStore >> Theme Settings >> Theme Custom CSS >> Global and then paste the below code at the bottom of the CSS box there.
.content-product .product-title{font-size:18px !important;}
Then save settings and check back to your site after clearing the browser cache.
Note: in the above code the word “18” is the size you can change it with you want.
3- Simply navigate to the Dashboard >> XSTORE >> Theme Settings >> Header Builder >> Secondary Menu >> see image: https://postimg.cc/tYGpJJtd
