## 説明

SlabCalc adds a free, embeddable concrete calculator to any WordPress page or post
using a simple shortcode. Visitors can estimate how much concrete they need for 
slabs, driveways, and patios — in cubic yards, cubic feet, or cubic meters — without
leaving your site.

**What it does:**
 * Calculates concrete volume and bag counts instantly * Supports
slabs, driveways, and patio projects * Works in imperial (feet/inches) and metric(
meters/cm) * Includes material cost estimates * Mobile-responsive, no setup required

**Usage:**

Add the shortcode to any page or post:

    ```
    [slabcalc]
    ```

Or specify a calculator type:

    ```
    [slabcalc type="driveway"]
    [slabcalc type="patio" width="400px"]
    [slabcalc type="slab" theme="dark"]
    ```

**Shortcode attributes:**

 * `type` — Calculator type: `slab`, `driveway`, `patio`, or `tube` (default set
   in Settings)
 * `width` — Widget width, any CSS value (default: `100%`)
 * `theme` — Color theme: `light` or `dark` (default: `light`)

## インストール

 1. Upload the `slabcalc-calculator` folder to `/wp-content/plugins/`
 2. Activate the plugin through the **Plugins** menu in WordPress
 3. Add `[slabcalc]` to any page or post

To set a default calculator type, go to **Settings > SlabCalc**.

## FAQ

### What shortcode attributes are available?

type (slab, driveway, patio, tube), `width` (any CSS value), and `theme` (light,
dark).

### Do I need an account to use this plugin?

No. The widget is completely free and requires no account or API key.

### Will this slow down my site?

The widget script loads asynchronously and only on pages where the shortcode is 
used. It has no impact on pages without the shortcode.

### Can I use multiple calculators on the same page?

Yes. Place `[slabcalc type="driveway"]` and `[slabcalc type="patio"]` on the same
page and both will render. The embed script is loaded only once regardless of how
many shortcodes are on the page.

### Does it work with page builders?

Yes, any page builder that supports WordPress shortcodes (Elementor, Divi, Beaver
Builder, Gutenberg shortcode block) will work.
