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 and visited your website.
1) To reduce the space over the slider on mobile you need to add the following Custom CSS in the Custom CSS for Mobile area under Theme Settings >> Custom CSS.
.site-content {
margin-top: -15px;
}
You can adjust the value according to your needs.
2) To center the cards image to center on mobile you need to add the following Custom CSS in the Custom CSS for Mobile area under Theme Settings >> Custom CSS.
.min-footer img {
margin-left: 55px;
}
3) To Display prices with tax you need to set up taxes from WooCommerce. You can read the following article for further help: https://docs.woocommerce.com/document/setting-up-taxes-in-woocommerce/
Best Regards.
