Make your site look better of the iPhone
Touting your mobile chops sets the bar a little higher than you've hit on an iPhone in portrait orientation. The "feedback" button covers code and there's a section that may read "live tutorial" but I'm not sure as it's not legible.
I’ve updated the Live Tutorial block so you shouldn’t have a problem with it anymore.
Can you provide more info on the Feedback issue? Admittedly I’m on Android 4.2.2, so don’t share your iPhone experience, but any info you can provide would be helpful.
You can reach me at email@example.com.
