Ricardo and Brian both explained that .is('.btn px') tests for a <px>
element inside an element with class="btn" - not an element with class="btn
px".
You don't have a <px> element, do you? If not, then your code that sets the
background color is never being executed.
Try putting an alert() or a console.log() in that code and see if it gets
there.
To illustrate further, try these tests in Firebug:
$('<div class="btn px"></div>').is('.btn px')
returns false.
$('<div class="btn"><px></px></div>').children().is('.btn px')
returns true.
