WooCommerce core does not provide AJAX add-to-cart on the single product page or for variable products listed on archive pages (it redirects to the single view). This plugin adds an unobtrusive AJAX workflow for:
<ul>
<li>Simple products (single product page button becomes AJAX)</li>
<li>Variable products on archive & block-based Product Collection (opens an accessible modal to choose attributes, then adds via AJAX)</li>
<li>Classic themes and modern block/FSE themes (2025 and later) with Product Collection blocks</li>
</ul>
Highlights: 
* Works with WooCommerce fragments (mini-cart updates automatically) 
* Accessible modal (focus trap, ESC to close, restore focus) 
* Nonce-secured AJAX endpoints; sanitized and validated input 
* Settings page to enable/disable variable product archive functionality 
* Block theme compatibility (intercepts “Select options” buttons) with slug/product_id fallback 
* Performance-minded (loads minified bundles built via Webpack; falls back to source if missing) 
* Translations auto-loaded from WordPress.org (no manual POT/PO generation required)
Privacy: This plugin does not send any data to external services. It only uses WooCommerce cart/session APIs.
<h3>Development</h3>
Build commands:
<ol>
<li>Install dependencies: 
npm install</li>
<li>Production build (minified + source maps): 
npm run build</li>
<li>Watch during development: 
npm run watch</li>
<li>Lint JS: 
npm run lint</li>
</ol>
Translations: WordPress.org language packs auto-load this plugin’s strings. The former POT/PO/MO tooling and i18n loader file were removed (WP 4.6+). Do not add a load_plugin_textdomain() call; simply keep the Text Domain header accurate.

Ajaxified Cart

AJAX add-to-cart for WooCommerce: simple & variable products on archives/blocks via accessible modal and instant cart refresh.

The new generation og WordPress themes are known as Block Themes, sometime referred to as Full Site Editing (FSE) or Gurenberg Themes.
These themes disable the older customizer, on the presumption that all styling can be done via the editor.
Unfortunately this is not so, and some styles still need custom CSS if you want to perfect your designs.
There are several plugins that allow you to add additional CSS however there is no need to add another plugin as the ability is still within Core WordPress, in the form of the customizer.
All it needs is it to be switched back on – no bloat- just a switch and you can then access the customizer and add additional CSS.
This is a really lightweight plugin that adds back the customizer when hidden by block themes.
The customizer is useful for block themes mainly because of Additional CSS.
Whilst it is still available for block themes, it is hidden. This plugin simply brings back the links.

Nice, simple, and does exactly what it says. 

It's getting the job done.
