Hello,
1) Blog on the home page is ok https://prnt.sc/20n1jko Oe what exactly do you want to change?
2) go to Theme Options > WooCommerce > Shop Elements > Variation swatches > Swatch Position > choose disable.
3) We fixed errors of the checker related to our theme. You need to add alt texts for your images to fix the errors that are left. Also, it’s not possible to fix the i (italic) element used error https://prnt.sc/20n24hl
i element used for the icons not just by our theme but Wishlist plugin, Elementor etc. It can’t be changed.
Regards
