## Basics
Create a slider by adding the class `.slider` and the attribute `data-slider` to a container element. You should also define both a starting and maximum value for the slider.
Inside the container are three elements:
- The handle (`.slider-handle`), which the user drags.
- The fill (`.slider-fill`), which resizes dynamically based on where the handle is.
- A hidden ``, which is where the value of the slider is stored.
The `data-initial-start=""` value is where along the slider the handle starts. The `data-end=""` is the maximum value for the slider. In the below example, starting at 50 of 200 means the slider handle will start at 25% of the total.
```

## Disabled
Add the class `.disabled` to disable interaction with the slider.
```html_example
```

## Two Handles
Two-handle sliders can be used to define a range of values, versus a single value. To make a two-handle slider, add a second handle, and a second ``. This works with horizontal and vertical sliders.
You can add IDs to the ``s inside the sliders to make it easier to access the values. If you don't, the plugin will add an ID to each for you.
Note that the first handle manipulates the first ``, while the second handle manipulates the second ``.
```

## Data Binding
Data binding allows you to connect the slider to an external `` field. With data binding set up, dragging the handle will change the value inside the text field, and editing the number in the text field will move the slider in real-time.
To set it all up, create an `` with an ID and add `aria-controls="id"` to the slider handle, where `id` is the ID of the ``.
```

## Native Range Slider
In Foundation 6.2, we introduced styles for ``, the native HTML element for range sliders. It's not supported in every browser, namely IE9 and some older mobile browsers. [View browser support for the range input type.](http://caniuse.com/#feat=input-range)
```html_example
```
If you're using the Sass version of Foundation, add this line to your main Sass file:
```scss
@include foundation-range-input;
```
It's possible to use both the JavaScript slider and the native slider in the same codebase, as the CSS selectors used don't overlap. Here's what's different about the native slider:
- Less markup: just write `` and you're good.
- No JavaScript is needed, which guarantees it runs faster in most browsers.
- To disable the slider, add `disabled` as an attribute, instead of a class.
- No support for vertical orientation.
- No support for two handles.

## Non-linear value translation
Sometimes not every value is of equal importance. In the example below, the slider focusses on the higher numbers by adding a `log`-type position value function.
Alternatively there is also a `pow`-type position value function available, making the reverse possible.
The nonLinearBase-option is optional and defaults to 5.
```html_example
```
## Reflow
The slider takes into account the width of the handles when calculating how to display itself. This means that if the slider is initially hidden, or hidden while the value is adjusted, the resulting visual will be slightly different because the width of the handle is indeterminate. If this is problematic, you can use JavaScript to cause the slider to reflow at the time that you change it from being hidden. Example:
```js
$('#my-slider').show();
$('#my-slider').foundation('_reflow');
```
