Whenever possible, LazyLoad will automatically load resources in parallel while ensuring execution order when you specify an array of URLs to load. In browsers that don't preserve the execution order of asynchronously-loaded scripts, LazyLoad will safely load the scripts sequentially.
Use LazyLoad when you need a small, fast, safe dynamic JS or CSS loader, but don't need the overhead of dependency management or other extra functionality that larger script loaders provide.

Using LazyLoad is simple. Just call the appropriate method --
css() to load
You can also provide a callback function if you'd like to be notified when the
resources have finished loading, as well as an argument to pass to the callback
and a context in which to execute the callback.
- Firefox 2+
- Google Chrome
- Internet Explorer 6+
- Opera 9+
- Safari 3+
- Mobile Safari
Other browsers may work, but haven't been tested. It's a safe bet that anything based on a recent version of Gecko or WebKit will probably work.
All browsers support parallel loading of CSS. However, only Firefox and Opera currently support parallel script loading while preserving execution order. To ensure that scripts are always executed in the correct order, LazyLoad will load all scripts sequentially in browsers other than Firefox and Opera. Hopefully other browsers will improve their parallel script loading behavior soon.
