Actions are features in your editor which allow you to add a trigger (roll-over, mouse-click) and corresponding action(s) to any element on your website allowing for a high level of visitor interaction and engagement. For example, you can create your own play, pause and stop button for video files or make an element behave in a certain way.
You can use actions to animate your site, draw users attention to specific areas of a page and create that impressive website with a rich user experience gained.
