Design an HTML template for a grocery store

I need a website design for an ecommerce site that does same day grocery delivery. Prefer the site design to be simpler - not too many colors/elements. The deliverables are HTML and CSS files. - Products are arranged into categories / brand. One way to depict available categories and vendors is in a column on the left side. - Some product images are of different size. However, when the products are displayed in a row, all products should take fixed width and height. See the first image and second image in the attached mockup- the product description is not aligned. Using CSS alignment should be possible. - Background should be white - Suggest using Green / Orange /other colors for buttons, header, menu item colors, etc. - Design must be responsive - should look nicer on both desktop, mobile and tablets. - 'Add to cart' button should be displayed next to each product. When an item is added, the number of items in the cart displayed in the header should be updated. - On hover over the cart icon in the header, cart contents should be displayed. Let me know if you need more details. Example: [login to view URL] --> didn't like the top-level header. Prefer it to be somewhat simpler. [login to view URL] --> simple and elegant. This is for WooCommerce/WordPress. I need simple HTML so that I can convert it to my site.
