## Overview

The MYDS HTML/CSS Toggle (Switch) is a lightweight, accessible interaction component used to toggle between two states. It is built using semantic HTML (checkboxes) and CSS transitions to provide a native-feel experience with three standardized sizes.

## 1. Setup

Import the following stylesheets to ensure the toggle displays correctly.

```html
<link rel="stylesheet" href="reset.css" />
<link rel="stylesheet" href="./toggle.css">
<link rel="stylesheet" href="./toggle-dark.css">
```

This guarantees that:

1. The **CSS reset** applies first.
2. The **toggle base styles** override the reset where necessary.
3. The **dark theme styles** apply last, so they can override both the reset and base button styles when needed.

## 2. Usage

To implement a toggle, wrap a hidden input and a track span inside a label. Apply the size modifier (sm, md, or lg) to both the label and the track.

```html
<label class="toggle-label-myds toggle-md-myds">
<input type="checkbox" class="toggle-input-myds">
<span class="toggle-track-myds track-md-myds">
<span class="toggle-thumb-myds"></span>
</span>
</label>
```

## 3. Sizes

### Small (sm)

<Tabs items={["Preview", "Code"]} defaultValue="Preview">
<Tab value="Preview">
<div className="flex justify-center">
<Toggle size="small">
<ToggleThumb />
</Toggle>
</div>
</Tab>
<Tab value="Code">
```tsx
<label class="toggle-label-myds toggle-sm-myds">
<input type="checkbox" class="toggle-input-myds" />
<span class="toggle-track-myds track-sm-myds">
<span class="toggle-thumb-myds"></span>
</span>
</label>
```
</Tab>
</Tabs>

### Medium (md)

<Tabs items={["Preview", "Code"]} defaultValue="Preview">
<Tab value="Preview">
<div className="flex justify-center">
<Toggle size="medium">
<ToggleThumb />
</Toggle>
</div>
</Tab>
<Tab value="Code">
```tsx
<label class="toggle-label-myds toggle-md-myds">
<input type="checkbox" class="toggle-input-myds">
<span class="toggle-track-myds track-md-myds">
<span class="toggle-thumb-myds"></span>
</span>
</label>
```
</Tab>
</Tabs>

### Large (lg)

<Tabs items={["Preview", "Code"]} defaultValue="Preview">
<Tab value="Preview">
<div className="flex justify-center">
<Toggle size="large">
<ToggleThumb />
</Toggle>
</div>
</Tab>
<Tab value="Code">
```tsx
<label class="toggle-label-myds toggle-lg-myds">
<input type="checkbox" class="toggle-input-myds">
<span class="toggle-track-myds track-lg-myds">
<span class="toggle-thumb-myds"></span>
</span>
</label>
```
</Tab>
</Tabs>

## 4. States

The toggle handles the following states automatically through the native checkbox:

* **Unchecked:** Default state with a neutral gray track.
* **Checked:** Primary blue track with the thumb translated horizontally.
* **Hover:** Subtle background color shift on the track.
* **Focused:** Accessible 2px ring visible during keyboard navigation (`Tab`).
* **Disabled:** Input becomes non-interactive (Add `disabled` attribute to the input).

| ------------------------ | -------------------------------------------------------|
| `.toggle-label-myds` | Wrapper that defines the hit area. |
| `.toggle-input-myds` | Hidden native checkbox managing the state. |
| `.toggle-track-myds` | The visual background/container of the toggle. |
| `.toggle-thumb-myds` | The sliding white circle component. |
| `.track-[size]-myds` | Controls size-specific dimensions and translation math.|



## 6. Customization

You can change the "active" color by overriding the checked state:

```css
.toggle-input-myds:checked + .toggle-track-myds {
background-color: #10b981; /* Changes blue to emerald */
}
```

## 7. Accessibility

* **Semantic:** Uses `<input type="checkbox">` so screen readers identify it as a toggle/switch.
* **Keyboard Support:** Fully navigable via `Space` and `Tab`.
* **Aria-Labels:** For better UX, it is recommended to add `aria-label="Toggle setting name"` to the input.
