Hello,
I see you are using an extra menu list widget in an HTML Block. The Extra Menu List element doesn’t have a built-in option to change the icon/image size, so it defaults to 18×18px. If you’d like to use a different size, please do the following:
Add a custom class custom-menu-icons to the Extra Menu List element (see example:
https://postimg.cc/9R9nXfmj)
Then add this CSS in Theme Settings > Global Custom CSS:
.custom-menu-icons {
--nav-img-height: 30px;
}
Change 30px to the size you prefer.
Best Regards
