叮叮内置的容器是什么样的浏览器内核是什么版本是多少？跟系统本身的浏览器内核有没有关联？我要确认有一些html5的特性，支不支持。

为什么不可以该浏览器不支持html5 ，请使用高版本浏览器或者使用极速模式！！这样不可以播放为什么哪？？？？

不放入标签，HTML5还会工作吗？

一个不用flash做的视频弹幕如何实现？后台语言和数据库选什么比较好？

划线 var c=document.getElementById("myCanvas"); var can=c.getContext("2d"); can.strokeStyle="rgb(0,182,0)"; var pois=new Array(); can.lineWidth=2; mycanvas.onmousedown=function(e){ can.clearRect(0,0,500,500); e=window.event||e; var sX=e.pageX-this.offsetLeft; var sY=e.pageY-this.offsetTop; var poi=Object.create({x:sX,y:sY}); pois.push(poi); if(pois.length==1) { can.beginPath(); } if(pois.length>1) { can.moveTo(pois[0].x,pois[0].y); for(var i=1;i

html5消息推送，要能实现心跳机制，并且服务端可用C#编写。

html5静态页面含有中文(google)加载很慢(不含中文正常)并报错net::ERR_CINTENT_LENGTH_MISMATCH,

在HTML5中web存储具有哪些和其他存储不同的特性？

首先是不能通过服务端转发数据哦，然后要传的参数是数组，如果太多的话，用querystring也不好，然后用cookies是可以，但是cookies的本意不是这样用的，而且我以前依稀听说html5有一种更好的传值方式的，请问那个是什么？
