How to Get Full Width Header and Footer on Product Category Pages

Hello, I’ve set all pages on my website to 100% width. The page width of product category pages, however, is not 100% width, but appears to be the default page width. How can product category pages be set to 100% width? For example, see https://cascadeintegrativepharmacyofseattle.com/product-category/designs-for-health/

Thank you.
