I'm fairly new to web dev and Rhomobile as well, so forgive me if this isn't a rhomobile specific question.
I followed this the JQuery Mobile tutorial, then removed my jquery mobile code with simple CSS. http://docs.rhomobile.com/rhodes-jquerymobile
When I just load the code into the browser, the page loads fine, so I think I'm at least on the right track.
My index.erb it just a div for the content (where I dynamically write everything) and my layout.erb is as barebones as possible as well.
Are there any known problems with respect to loading CSS on dynamic content I should know about? Alternatively, are there any tips anyone can provide to aid me in debugging?
We do ship a WebInspector with RhoStudio that will allow you to debug your CSS. It should launch as a separate window when you run your app in the RhoSimulator.
