I am building my first responsive site and I am using DreamweaverCS6 to do it with. My question is, will an iPhone or iPad (for example) work ok with a pure css navbar?
Any help would be appreciated
Regards
Tony
It will work … if it’s done properly. 
There are hundreds of ways to go about this, so the question is too open. Feel free to post your code when you have some. 
Remember that ipads or iphones don’t have :hover capability as such so if you are creating a dropdown hover menu then they may not work as you expect. For mobile and tablet its best to add a little js and do a click menu instead.
