The app.js file is blank when I preview.
I saved the app.js file, but when I try to preview, in the Sources tab there is an app.js file, but it is totally blank. What can I do now?
You'll want to preview the index.html file not the app.js file. js is just the backbones to make it all work, the html file is where all the visual stuff happens.
