javascript - Headroom.js options with Enquire.js -

i need have different offset in headroom.js depending on screen size.

enquire.js should trick, can't work properly. loads 1 offset setting per page load, though it's right 1 on load, doesn't switch setting when resize screen.

enquire.register("screen , (max-width: 48rem)", {    // required   // triggered when media query transitions   // *unmatched* *matched*   match : function() {        headroom.options = {          offset : 0, };   },    // optional      // triggered when media query transitions    // *matched* *unmatched*                           unmatch : function() {  headroom.options = {          offset : 137, };    },        // optional   // triggered once upon registration of handler   setup : function() {    },          // optional   // defaults false   // if true, defers execution of setup function   // until first media query matched (still once)   defersetup : true            });
