HTML5 support in Internet Explorer and Microsoft Edge is lagging behind other major browsers. For example, they don’t support "masking" animations in HTML5 content.
As a result, the following Storyline 360 and Storyline 3 animations and transitions won’t work when you view HTML5 courses in Internet Explorer or Microsoft Edge. They also won't work in CD-published output since it relies on Internet Explorer.
Slide and Layer Transitions
Here are some suggestions for working around this Microsoft limitation:
- View the Flash version of your course instead.
- Use a different animation or transition in your Storyline course.
- Use a different web browser, such as Google Chrome or Firefox.
