I'm redesigning and rebuilding an existing fixed-width website to make it responsive and mobile optimized. I'm trying to stay as close to the original site as possible.
However, it uses a lot of overlays. They are used to show larger versions of images as well as 'pages' that have an image as well as a few paragraphs of text.
Example of an overlay: http://lokeshdhakar.com/projects/lightbox2/
Tablets can probably handle them but I assume that phones will probably struggle with overlays. Are there any smart solutions to this?
