Hello, @Andrés,
1. Please copy and paste the below-given CSS code to XStore >> Theme Settings >> Theme Custom CSS >> Global CSS and check back to your site after clearing the browser cache.
.woocommerce-pagination.sb-hide {
visibility: visible !important;
}
2. Please copy and paste the below-given CSS code to XStore >> Theme Settings >> Theme Custom CSS >> Desktop CSS and check back to your site after clearing the browser cache.
.item-design-mega-menu .nav-sublist-dropdown>.container>ul>li {
margin-bottom: 0.5em !important;
}
Please share the screenshot that which title and subtitle you want to make bold in the mega menu so that I’ll check and provide you with the proper and particular solution for it.
3. You can change the Body & heading Font from XStore >> Theme Settings >> Typography. And you can check the element settings which you are using on your site for the typography option, if it has then you can change it from the element settings Otherwise you have to change it using Custom CSS.
