Random Movement in a Fixed Container

Question

I\'m looking to create something that can move randomly inside of a fixed div container. I love the way the object moves in this example that I found searching this website...

Answer 1

Add a wrapper element around it and update the jQuery to limit the dimensions.

​

// Get viewport dimensions (remove the dimension of the div)
    var h = $('#wrap').height() - 50;
    var w = $('#wrap').width() - 50;

Here's an updated fiddle: http://jsfiddle.net/Xw29r/375/
