The Heartcode CanvasLoader is a lightweight JavaScript UI library, which uses the HTML5 Canvas element to draw and animate circular preloaders. The Heartcode CanvasLoader runs in every ‘good’ browser which supports the HTML5 Canvas element.

To build your custom preloader, use the “CanvasLoader Builder” section. There is a bunch of parameters you can play with. If you are happy with your preloader, use the code snippet or download your custom HTML example file which contains your CanvasLoader instance and the embedding instructions.
