This is an example of a minimal mobile-friendly modal window. It is developed without using a plugin and with just a few lines of jQuery. Resize your browser to test how it behaves on mobile. <br><br> The functionality is very basic, so you would probably have to built upon it regarding your project needs. Feel free to use this script in any personal or commercial projects.
