Firefox CSS3 isosceles triangle rendering issues -

i'm trying create isosceles triangle using css3 , looks firefox can't render them properly? is there way of fixing that? here's example: http://jsfiddle.net/wajly/1/ css: .arrow { vertical-align: middle; content: ""; border-right: 50px solid transparent; border-left: 50px solid transparent; border-top: 75px solid #222; width: 0; height: 0; } html: <div class="arrow"></div> (firefox renders 1 on left) seems firefox still has problems jagged lines. workaround: came accross workaround: example maybe helps out - no guarantee. alternative i: make borders same size (in example e.g. 50px) not see jagged lines. can scale size of arrow border-size. alternative ii: use image (should not huge request / load time ...) edit: got work!: jsfiddle trick add line of code: border-style: solid dotted none; best regards.

ember.js - "Resolved all models on destination route, finalizing transition". But Ember renders 'view:loading' -

-
router calls hooks hangs in finalizing transition renders view:loading . the problem is, don't know why ember isn't finalizing transition, far know models:menus fetched , categories sideloaded. both categories , categories.index routes defined. categories , categories:index controllers defined , ember.arraycontroller.extend({}) categoriesroute export default ember.route.extend({ model: function(params){ return this.modelfor('menus').findby('id', params.menu_id).get('categories'); } }); categoriesindexroute export default ember.route.extend({ model: function(params){ return this.modelfor('categories'); } }); what ember logs: https://gist.github.com/pekhee/b07917dcf6d9f78bb7d1 due lack of template controller, ember hangs in finalizing transition since can't render template. i'm not 100% sure though, apparently of mar 2014 ember app kit grunt server task isn't compiling new files.
