Can't get a demo to work about re-flex

[leefsmp]

It's a css issue, add for example:
.App { height: 100px; }

At least one parent of the ReflexContainer must have a heightproperty. It could be for example Body with height: 100vh and then you have App with height: 100% if you have to use relative values.

I should add that in the doc/demos at some point. Hope that helps.
