I've been working with an HTML5 document with inline SVG and javascript animation. I'd like to have a box pop up when the user clicks anywhere, and I'd like the box to go away when the user clicks somewhere that isn't the box. This means I can't use $(window).click(), which works. I've tried selecting the SVGs on top by giving them cla...
