i have error

uncaught typeerror: cannot set property 'backgroundcolor' of undefined  

this

$.csshooks // gives me undefined 

in jquery found extend

jquery.extend({     // add in style property hooks overriding default     // behavior of getting , setting style property     csshooks: {         opacity: {             get: function( elem, computed ) {                 if ( computed ) {                     // should number opacity                     var ret = curcss( elem, "opacity" );                     return ret === "" ? "1" : ret;                 }             }         }     }, 

how can implement csshooks jquery in zepto???

tnx

edit 2

i found posible solution problem implement ccshooks myself

jquery.csshooks= {     opacity:      {         get: function( elem, computed )         {             if ( computed )             {                 var ret = curcss( elem, "opacity" );                 return ret === "" ? "1" : ret;             }         }     } }; jquery.fx.step = {}; jquery.easing = {     linear: function( p ) {         return p;     },     swing: function( p ) {         return 0.5 - math.cos( p*math.pi ) / 2;     } }; var originalqsa = jquery.zepto.qsa;  $.zepto.qsa = function(el, sel) {   try {     return originalqsa.apply(this, arguments)   } catch(e) {     console.error("invalid css selector: ", sel)     return []   } } 

this extends zepto csshooks. event handler cause problem

$('#menu a').click(function()     {         var name=$(this).attr('id');         var div=$('div#'+name);         var visible=$('#container').find(':visible').attr('id');          $('div#'+visible).css({position:'absolute'}).hide('slide',{direction:'left'},1000,function()         {             $(div).css({position:'relative'}).show('slide',{direction:'right'},1000,function(){resetsizegmaps()});           });     }); 

but trace error try/catch ive been created

invalid css selector:  :visible  

can fix csshooks??
