# TransformJS 1.0 Beta

### 2D and 3D transforms as regular CSS properties you can set using `.css()` and animate using `.animate()`

## Overview

  CSS Transforms  were first introduced in WebKit in 2007, and have now 
reached mass-adoption by all the major browser vendors. This is great news 
for web developers, especially in the case of 3D transforms which are
hardware-accelerated, resulting in extremely smooth animations and
responsive applications. 

  The API for applying transforms however, does not scale to complex applications 
which require intricate and complex management of transformations. TransformJS
attempts to identify and address these problems, allowing developers to
make use of transforms without having to be encumbered by cross browser
issues, and low-level APIs.

  Here's a snippet of code that uses TransformJS to apply multiple 3d
transformations to the same element, relative to their current value,
and animate the changes:

```javascript
    $('#test').animate({
      translateY:'+=150',
      scale:'+=2',
      rotateY: '+=6.24',
      rotateX: '+=3.15',
      rotateZ: '+=3.15'
    },1500);    
```

project homepage at http://transformjs.strobeapp.com
