Hello,
First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :).
I saw the screenshot you attached.
1) Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.
.product-grid-item .wd-product-brands-links {
text-align: center;
}
2) Sorry but there is no option in Theme Settings available for that.
3)Please try adding the following Custom CSS in the Custom CSS for Mobile area under Theme Settings >> Custom CSS.
.wd-sticky-btn .single_add_to_cart_button, .wd-sticky-btn div.quantity {
background-color: red;
}
4) To change the icon try adding the following Custom CSS in the Custom CSS for Mobile area under Theme Settings >> Custom CSS.
.wd-menu-icon > a:before {
content: "\f107";
}
5) You can create attributes from Products >> Attributes then you need to use them for the products then you can display them in the Shop filters by adding widgets to the Shop page widget under Appearance >> Widgets.
6) Sorry but there is no option in Theme Settings available for that.
Regards.
