Just place the SmoothHTMLTransitions External HTML object at the title level of your Lectora Course and voila! Then delete this page when you are done looking at it. This page is just an example of how you can use it.
Use transitions as you normally do. Supported transitions (listed below) will automatically be converted to Smooth Transitions when you publish or preview in HTML. Even your speed setting will be taken into account.
Dissolve (Opacity Fade)
All Flys (Flys, Plus Opacity Fade)
Move To/Size To New!
The Dissolve transition becomes a smooth fade transition in HTML. In this example there are three Firework pngs with both trans in and out set to dissolve. They have different delays on each firework so it feels random.
Fly transitions still fly in, but not from off the entire page. By default they fly in from 200 pixels away, but can be changed in the in the options section. Also fly effects are automatically paired with a fade effect for a professional look.
Click each object to see some different ease settings with a Move To action. (These don't work too well in Chrome)
