Severe jQuery lag on Firefox & Chrome, not IE though -


as stated in title, one-page site minimal jquery suffering crazy lag on chrome , firefox, not on ie10. realize ms stepped game 10, sweet lord's sake, deal?

i've read chrome laggy div hide()s , show()s, i'm using fadein() , fadeout(), , seems there's i'm missing.

i've created jsfiddle in case i've somehow done horrifically wrong.

http://jsfiddle.net/g2avityhitz/zdqed/1/

(function($){     $(document).ready( function () {         $("#picbox .tiny img").click( function () {             $("#picbox .tiny img").removeclass('selected');             $(this).addclass('selected');             imgsrc = $(this).attr('src');             $("#picbox .main").css({                 'background-image'  : 'url(' + imgsrc + ')'             });             $("#picbox .main a").attr('href',imgsrc);         });          $("#picbox .main a").click( function (e) {             e.preventdefault();             imgsrc = $(this).attr('href');             $("#lightbox .frame img").remove();             $("#lightbox .frame").append('<img src="' + imgsrc + '" />');             $("#lightbox").fadein(500, function () {                 $('#lightbox .frame .close').click( function () {                     $("#lightbox").fadeout(200);                 });             });         });     }); })(jquery);

please , thank you.

edit: great responses, point out again - no lag in ie, in chrome , firefox. behind this?

here example of caching optimize have.

will solve everything? not sure, things.

cached code:

var $images = $("#picbox .tiny img"),     $main = $("#picbox .main"),     $mainlinks = $main.find("a"),     $lightbox = $("#lightbox"),     $frame = $lightbox.find(".frame"),     $frameimages = $frame.find("img");      $images.on("click", function ()      {         var $this = $(this);          $images.removeclass('selected');         $this.addclass('selected');         imgsrc = $this.attr('src');         $main.css({ 'background-image': 'url(' + imgsrc + ')' });         $mainlinks.attr('href', imgsrc);     });      $mainlinks.on("click", function (e)      {            e.preventdefault();          imgsrc = $(this).attr('href');         $frameimages.remove();         $frame.append('<img src="' + imgsrc + '" />');         $lightbox.fadein(500, function ()          {             $frame.find(".close").on("click", function ()              {                 $lightbox.fadeout(200);             });              });     });  });

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
