## Descripción

**ClassyBlocks** transforms how you style Gutenberg blocks. Instead of wrestling
with theme CSS, writing repetitive rules, or switching back and forth between editors,
you can create and apply custom CSS classes directly from the block editor — with**
real-time preview** and **one-click application**.

Whether you’re building a simple landing page or a complex multi-site network, ClassyBlocks
keeps your workflow fast, consistent, and maintainable.

### Key Features

 * **Custom CSS Class Manager** — Create your own library of CSS classes with full
   support for `:hover`, `:focus`, `:active`, and `:visited` pseudo-states. Name,
   describe, and organize each class with its own CSS rules.
 * **9 Built-in CSS Frameworks** — Bootstrap 5.3, Materialize, Pure CSS, Bulma, 
   UIkit, Spectre, Semantic UI, Foundation, and Tailwind CSS. Toggle each framework
   on/off independently for the editor and the frontend.
 * **Live Preview in Gutenberg** — See exactly how each class looks in real time,
   directly inside the block editor. No more guesswork or page reloads.
 * **One-Click Application** — Apply any custom or framework class to a block with
   a single click. No typing class names manually.
 * **Pack Manager** — Export, import, and share complete sets of CSS classes as 
   packs. Perfect for agencies managing multiple sites or teams collaborating on
   design systems.
 * **Interactive Preview Mode** — Test your classes interactively with Auto and 
   Interactive modes that cycle through pseudo-states.

### What you can do

 * **Design faster** — Build a reusable library of utility classes and apply them
   across your entire site in seconds.
 * **Stay organized** — Group classes into packs by project, component, or design
   system. Search, filter, and manage everything from one dashboard.
 * **Work with any theme** — ClassyBlocks works with every WordPress theme. It integrates
   especially well with Blocksy, GeneratePress, Astra, and other modern block-ready
   themes.
 * **Keep performance tight** — The plugin generates a minimal, optimized stylesheet
   with zero JavaScript overhead on the frontend. No bloat, no slowdowns.

### Perfect for

 * **Developers and agencies** building client sites with consistent design systems.
 * **Freelancers** who want to speed up their Gutenberg workflow without custom 
   coding every time.
 * **Site owners** who want more design flexibility without installing a page builder.

**ClassyBlocks** — the smart way to manage CSS classes in WordPress.

### How it works

 1. Install and activate the plugin.
 2. Go to the CSS Classes section and create your own classes with the properties you
    want.
 3. Go to the page editor (Gutenberg).
 4. In the “CSS Classes” section of each block, you can select the plugin’s custom 
    classes.

You can easily combine classes to achieve complex results.
