Remove product description from header

I am using the Marquee template, which I am very happy with except for one instance. I just recently added a shop to my website through Printful and I noticed on the product pages, the header lists the products full description. This is really not necessary as all the same information is listed again below next to the product images. That and it is not a good look to fill the whole screen above the fold with the product info.

Customer support told me this is part of the templates so I would just need to pick a different one. However I have been using this template for years and am happy with it so changing would be less than ideal. 

Does anyone know how to troubleshoot or revise the code on the product pages specifically so the product information does not show in the header?

@kyla_w_johnson Product description probably can be hidden with custom css. Can you share your site URL? 

My site is https://www.houseohelga.com you can see one of the products here https://www.houseohelga.com/shop/the-og-unisex-t-shirt

@kyla_w_johnson You can add this code under Website > Pages > Website Tools > Custom CSS

.collection-type-products #productDetails .product-excerpt {
    display: none !important;
}

@Lesum that removed the product description from next to the product. I want it to stay there, just remove from the header. You can see here what happened when I entered that code https://www.houseohelga.com/shop/the-og-unisex-t-shirt

@Lesum That did it! thanks so much
