Description WDFN-689 (Add on)

Fixes issue where the download text was inheriting a 'flex' style which was overwriting the 'hidden' property. I added back a div that I removed to clean up the code. The div acts as a container which doesn't inherit the suspect flex property. I tried to fix the inheritance in a way that didn't require an extra div, but didn't have success.

I also added bit of additional style that had been present in earlier released versions of waterdataui, but had been lost.
