Hey, there are many ways this could be done. I don't know how it's done exactly in Coursera. Here's an example with basic jQuery: http://jsfiddle.net/TimFogarty/jUKwL/1/ http://jsfiddle.net/TimFogarty/jUKwL/1/ With a large number of courses and pictures, you'd probably want to use ajax to fetch the course info every time a box is ticked. Alternatively, you could use a framework like Angular.js: http://angularjs.org/ http://angularjs.org/ Hope that helps.
