Keystone Theme
Edition: CS-Cart & Multi-Vendor · Latest version: 1.0.0 · Compatible with: CS-Cart & Multi-Vendor 4.17.2 – 4.21.x, PHP 7.4 – 8.3 · Changelog: view
Keystone is a universal premium storefront theme for CS-Cart and Multi-Vendor 4.17.2 to 4.21.x. It is one modern, classic design that fits every kind of store: electronics, fashion, home, beauty, sport, toys, books or a marketplace. You give it your own look with twelve colour schemes (every colour also editable in the native Theme Editor) and three Block Manager layouts. The demo store is a consumer electronics shop.
Keystone is a child of the standard Responsive theme, so CS-Cart add-ons and your own add-ons keep working.
What you get
Section titled “What you get”- One design, your colours: twelve colour schemes (Ocean, Graphite, Emerald, Coral, Sunrise, Ruby, Teal, Indigo, Forest, Rose, Volt and the dark Midnight). Every Keystone colour follows the Theme Editor colours, so changing the menu, button, link, background or footer colour there changes the whole storefront consistently.
- Three layouts (normal Block Manager layouts you can edit): Market (Catalog button, menu bar in your brand colour, vertical catalog beside the hero), Classic (search-led header, menu bar, wide hero with side banners) and Showcase (one-row header, large split hero, light footer).
- Navigation: mega menu with category pictures or line icons, labels (New, Hot, Sale), top brands, the best deal and your own banners in every panel; vertical catalog with flyouts; “More” for items that do not fit; sticky header; live search with pictures, prices and categories; drawer menu and bottom bar on phones.
- Selling on the homepage: hero slider with a price sticker, category tiles and mosaic, product tabs, product of the day with a countdown, active promotions with “N days left”, deal countdown band, promo banners, “Shop the set”, a compact add-ons row, brands, customer reviews, blog posts and (Multi-Vendor) shops.
- Category pages: promo cells inside the product grid (one or two columns wide; a banner, a promotion with a live countdown, or an article or video that opens in a popup), set per category in the Block Manager; subcategory chips; active filter chips; “Show more products” instead of page links; filters in a bottom sheet on phones.
- Product cards: product code and stock status, stickers (sale %, New, Bestseller, the core labels), colour swatches of product variations (each swatch opens that variation), rating, wish list, compare, quick view and one-tap add to cart. Hide any card element on phones or on larger screens in the settings.
- Product page: large gallery (product videos of CS-Cart 4.21 and of our Product Videos add-on included), trust block, frequently bought together with one “Add selected to cart” button, sticky Buy bar on phones, related products.
- Multi-Vendor: styled vendor store header with logo, rating and product count; shop cards on the homepage.
- Demo content on activation: a complete electronics catalogue with pictures, variations, promotions, banners, blog posts and reviews, so the store is full right away.
