Hello,

6b. Try to use this one .single h4 span , please.

6f. I will forward it to the team.

6g. It’s a principle that when you put the font size it is given line height also so that strings don’t merge (https://gyazo.com/aaaa654a75dc2efd38d11794a38c44a8). If you set your custom size, also set the “Line height” (https://prnt.sc/25so0n3) as you need.

8. It was some bug from WooCommerce so we have prepared CSS code to fix it.

8b. Check this one, please.

.wd-list.wd-list-type-icon .list-icon {
    margin-top: 5px;
}
