Noteworthy Theme and Mobile Compatibility

Hello!!

I am currently using the Noteworthy theme and I noticed on my IPhone that it has a strange functionality. It’s all pushed into a single column but does not adjust to the screen…it stays small.

Is this caused by my custom header across the top? And if so, is there a better header plug in I can use “Simple Header Footer HTML”?

I really like this theme but if there is a better one for a “recipe/food blog” I would appreciate suggestions as well!

Thanks!
Jennifer
