Ladda Merges Loading Indicators into Buttons

Ladda is a set of buttons which merge loading indicators into themselves to bridge the gap between action and feedback. It’s a UI concept which merges loading indicators into the action that invoked them. Primarily intended for use with forms where it gives users immediate feedback upon submit rather than leaving them wondering while the browser does its thing.
