Thank you for this very simple and good Plugin.
Just a note for future releases as I had to struggle with the correct width and height of the colorbox. Please change the following lines in tablet-responsive.1.1.js as this:
//jQuery.colorbox.settings.width = "92%"; //jQuery.colorbox.settings.height = "98%"; jQuery.colorbox.settings.maxHeight = "90%"; jQuery.colorbox.settings.maxWidth = "90%";
So the colorbox is still responsive but resizes to the correct height and weight. Before it just resized the weight so there was always an ugly border.
Thanks and good job!
