I'm just beginning to build out a new site (mattfouty.com). I'm trying to get the logo to display at retina resolution on the iPhone. When I turn on the "always serve retina images" option, I can see that the plug-in is working on the desktop. I am served a retina image, in it's standard container. When I view it on the iPhone, I am getting an image at double the size, non-retina.
I've read your FAQs, and dug into the CSS. I found where there is a logo class in the CSS. I set the width to 125px and the height to auto. This is what seemed to fix the problem on desktop but for some reason it's not also working on iPhone.
Do you have any suggestions?
