Four Stacks, One Install
The first choice X puts in front of you isn't a color palette or a font — it's a Stack. Themeco's marketplace description identifies four of them: Integrity, Renew, Icon, and Ethos. Each is a complete visual direction, not a child theme or a skin swap, and the choice shapes how your header, typography, and content areas look by default.
What makes the Stack system practically significant is that WooCommerce shop pages, bbPress forum layouts, and BuddyPress community pages each have their own styled version per Stack. Switching from Integrity to Ethos, for example, changes the visual treatment across your shop, your forum, and your community pages — not just your homepage. That's worth considering before you commit to a Stack and build substantial content around it.
The Theme Options panel lets you select your active Stack and preview changes live. Beyond the Stack selection, the same panel covers layout (fullwidth or boxed), content column position, topbar, breadcrumbs, footer widget areas, and blog and archive display styles. Changes preview immediately without a browser refresh, and saving pushes them live.
Building with Cornerstone
X pairs with Cornerstone, its dedicated page builder, which the marketplace listing also names as a compatible plugin. According to the vendor description, Cornerstone provides over 100 prefab Elements organized into four categories: Layout Elements, Standard Elements, Dynamic Elements, and Woo Elements.
The Standard Elements cover the building blocks you'd expect — headlines, images, text, icons, video, audio, tabs, accordions, countdown timers, counters, testimonials, and social links, among others. Navigation gets its own set: Inline, Dropdown, Collapsed, Layered, and Modal variants let you build the nav structure directly in the editor rather than relying on a theme menu location. Cart interactions (Dropdown, Modal, Off Canvas) follow the same pattern for WooCommerce stores.
All Elements are accessible from within Cornerstone, which means layout, content, navigation, and commerce elements share a single editing context. That consistency matters when a site grows past the initial build and someone else is maintaining it.
Dynamic Content and Reusable Components
Dynamic Elements are where X's setup diverges from simpler page builders. The vendor describes a Dynamic Content system that can pull WordPress post meta and user meta, Advanced Custom Fields data, and other plugin data, then loop through records using Loopers. This lets a single template structure produce repeating output — a team directory, a product feed, a list of case studies — without duplicating layout work.
For sites consuming external data, the description notes an External REST API connection in Cornerstone, allowing third-party data sources to feed into the same Looper workflow.
Components and Parameters address a different problem: reuse and consistency across a site built by a team or across a long project lifetime. Components are reusable content blocks managed from a single location — editing the source updates every instance. Parameters go further, letting you define your own variables and build a design system with custom controls. If your project has a recurring structure — a pricing card, a feature highlight, a team profile — that can be designed once as a Component with Parameters and placed wherever it's needed.
Element-Level Effects Without Third-Party Plugins
Cornerstone includes an Effects Module that operates at the level of individual elements rather than at the page or section level. According to the vendor description, you can stack multiple effect types on a single element: CSS filters, transforms, interactions, positional effects, masks, and layer blending. The description describes these as native capabilities.
The practical implication is that effects like a parallax movement on a card, a blend mode applied to an image, or an interaction tied to scroll position don't require a separate animation plugin. Whether you use those effects at all is a design decision, but knowing they're available natively may affect what you'd otherwise need to install alongside X.
Typography at Scale
The vendor describes access to over 600 Google Fonts, with each font's available weights loaded dynamically rather than all at once. Within the Theme Options panel, separate controls exist for logo text, navbar links, headings, and body copy — each with independent size, color, weight, letter-spacing, and capitalization settings.
For a site where type consistency matters — a publication, a brand-heavy corporate presence — those granular controls reduce the need to override styles manually in custom CSS. For simpler projects, the same panel is still where you'd make those choices, so the depth is available without being required.
Compatibility: Plugins and WordPress Versions
The marketplace listing observed in November 2026 notes compatibility with WooCommerce 9.x.x, bbPress 2.6.x, BuddyPress 9.x.x, Gravity Forms, WPForms, WPML, and Cornerstone. WordPress version compatibility is listed from 5.6.x through 7.0.x according to the same vendor listing. These are vendor claims, not the result of independent installation testing.
WPML compatibility is relevant if you're building a multilingual site. Gravity Forms and WPForms both appear on the compatibility list, so if your project depends on either form plugin, X accounts for them. The vendor notes that bbPress styles are loaded only when the plugin is active, which means the theme won't carry that code weight if you're not using forums.
Questions & answers
Does X work with the WordPress block editor (Gutenberg)?
The marketplace listing marks X as not Gutenberg Optimized. Cornerstone is the intended editing environment. If your workflow relies on the block editor for day-to-day content editing, that's a meaningful constraint to check before committing.
