== Description ==

### Build Accessible, Responsive Tabs in the Gutenberg Block Editor

Whether you’re building a documentation page, a product features section, or a clean tabbed layout for content organization, this plugin helps you do it quickly and natively.

### Why Choose BlaBlaBlocks Tabs Block?

The **Tabs Block** plugin combines **modern WordPress standards** with **ease of use**. Built using the **WordPress Interactivity API**, it ensures lightweight performance, accessibility, and full compatibility with the latest versions of WordPress.

#### Key Highlights
- **Accessible Tabs:** WCAG-compliant markup, ARIA roles, and keyboard navigation support.
- **Zero Dependencies:** No jQuery or heavy JS frameworks powered by the **Interactivity API**.
- **Responsive by Default:** Tabs automatically stack or scroll on smaller screens.
-  **Horizontal & Vertical Layouts:** Switch between tab orientations with one click.
- **Ready-to-Use Templates:** Choose from prebuilt designs to jump-start your layout.

## #Key Features

* ARIA attributes for screen readers.
* Tab focus management for keyboard users.
* Semantic markup that works with assistive technologies.

#### 2. Responsive by Design
No need for custom CSS or media queries. Tabs automatically adapt their layout across screen sizes:

* On desktop: clean horizontal tab navigation.  
* On mobile: collapsible stacked layout or swipe-enabled scrolling.

#### 3. Horizontal & Vertical Tabs
Want sidebar-style navigation? Just toggle layout mode. You can switch between horizontal and vertical tabs at any time, perfect for documentation pages or feature lists.

That means:

* Faster loading and rendering.
* Better Core Web Vitals scores.

#### 6. Works Everywhere
Tabs Block is fully compatible with:

* Block Themes (Full Site Editing)
* Classic Themes using the Block Editor
* Reusable Blocks and Block Patterns
* Core blocks like Columns, Groups, and Cover
