Patternslib is a JavaScript library that enables designers to build rich interactive prototypes without the need for writing any Javascript. All events are triggered by classes and other attributes in the HTML, without abusing the HTML as a programming la

## Description

The Zoom pattern creates a zoom slider for any (group of) object the user should be able to change size of.
A very typical application of this pattern is a group of thumbnails that the user may change in size.
Please note that some browsers (for example Firefox) don't support the `zoom: x` CSS property required for this
pattern to work.

## Documentation

It's easy to make an element zoomable with Patternslib. Just add a `pat-zoom` class to it.

Here is a simple example:

    <img class="pat-zoom" src="image.jpg"/>

Upon seeing the `pat-zoom` class, Patternslib will prepend an input element with type `"range"`.

The user can use this range input to change the _zoom_ CSS property for the zoomable element.

For example:

    <input type="range" min="0" max="2" value="1" step="any"/>
    <img class="pat-zoom" src="image.jpg" style="zoom: 1"/>
