Isotope uses CSS3 transform to position item elements, when available in the browser. Setting `transformsEnabled` to <code><span class="kc">false</span></code> will disable this feature so all browsers use top/left absolute positioning.

## Problems with CSS transforms {: #css-transforms}
As the browser implementations of CSS tranforms are still a work-in-progress, they can cause buggy behavoir with other types of dynamic content.

### Disabling transforms
Set [`transformsEnabled`](options.html#transformsenabled) to `false`. This is an easy step to take when troubleshooting.
{% highlight javascript %}
$('#container').isotope({
// options...
transformsEnabled: false
});
{% endhighlight %}
## Accessing the instance
[Similar to jQuery UI](http://docs.jquery.com/UI_Developer_Guide#Internal_functions_.26_scopes_explained), Isotope stores a instance containing properties, settings and methods with jQuery.data. You can access the instance with the `'isotope'` namespace.

If you do plan on implementing Infinite Scroll with filtering or sorting (which is a _bad idea_), use the `insert` method instead of `appended`.
## Flash
[Using CSS transforms with Flash content is a bit buggy in Safari and Firefox](http://dropshado.ws/post/4085720152/css-transforms-breaking-flash). This is problematic when using Isotope on item elements that contain Flash content like YouTube or Vimeo videos, Flash ads, or Flash audio players.
The best way to resolve this issue is to disable CSS transforms by setting the [`transformsEnabled` option](options.html#transformsenabled) to <code><span class="kc">false</span></code> and removing scale from [visibleStyle](options.html#visiblestyle) and [hiddenStyle](options.html#hiddenstyle) options.
{% highlight javascript %}
$('#container').isotope({
// options...
transformsEnabled: false
});

## Poor type rendering in WebKit
Type rendering may appear poor in WebKit browsers like Chrome and Safari. This is because of Isotope's activation of hardware acceleration. The solution is to add add a matching background to the item elements.
