Really appreciate these additional courses! Thanks much!

Curious if there is a way to play around with the fractional size property to create a kind of scaling effect so that each item dynamically enlarges when swiped into center view, like in a horizontal carousel?

I followed your suggestions and played around with parameters. At first I cannot understand clearly the difference between group and item. But when I used absolute dimension for widthDimention, say, 80 for item's absolute width dimension and 400 for group's absolute width dimension, group(s) of four items showed and the fog cleared away. Now I understand how group and item function and interact with each other.
