Newbie Needing Some Small Customization and Layout Help

[temdarrell]

I'm New to AbanteCart, Have an existing Cart running on my site that is very user friendly but very limited in features.  I Like what I see in AbanteCart but because I don't have any code knowledge or experience. I'm reaching out for some help in the layout and appearance. The site looks beautiful on PC but Crazy on Mobile devices..   development.trendzbytrena(dot)com  is the AbanteCart Site
trendzbytrena(dot)com is the cart I want to replace
