NOTE: in this example I am using 'height', but I will be querying other css properties also.
I have media queries that are setting an element's height.
I have an angular directive that watches that height.
The height changes when window is resized (manually), and the watch function is called (via .digest()), but the .css('height') is empty.
return element.css("height") ; // --> nothing
please see my plunker.
