We recently updated one of our plugins (other developer), and one of it's two views stopped re-sizing for different screen sizes. The plugin changed it's structure a little, but there are still just two main views, but now have some partial views called within them.
The problem seems to be the Side-2 class is not using the alternate stylesheets, like 480.css, etc..and keeps using the 220px definition from the main stylesheet, even when viewed with a smaller device...at least, that's what it SEEMS like...I don't know for sure. I've tried many things but cannot get it to look like it did before.
Here's a normal page on my site which behaves correctly:
This is the view from the plugin which is still responsive:
And here is the plugin view that is no longer responsive:
Can you see a reason for this problem?
