我首先做哪些工作精美提琴。在小提琴使用样式

I first made a fiddle which worked beautifully. Styles used in the fiddle are

（演示这里）

现在我复制，为了我的CSS我在Visual Studio中并运行它。令我沮丧，我发现我不能看到 newbuttonbar 可言。我问萤火虫，他们告诉我没有 newbuttonbar 中定义的。

Now I copied that to my css inside my visual studio and ran it. To my dismay I found that I could not see a newbuttonbar at all. I asked firebug and they told me there is no newbuttonbar defined at all.

此外，即使没有应用其风格仍然显示在Firebug的CSS控制台

Also even though the style is not applied its still displayed in Firebug CSS console

最后，我找到了原因，因为这。 （我不知道这是否是正确的的）结果
CSS编辑器抱怨说 newmainblock 是

At last I found the reason as this. ( I am not sure if this is correct )
The CSS editor complains that newmainblock is

缺少样式规则的选择

因此​​，它省略了后 newmainblock ，仅仅自带的标签。这就是 newbuttonbar 。所有其他样式都考虑在内。为什么出现这种情况，我是什么做错了，如何纠正呢？

So it omits the tag that just comes after newmainblock. That is newbuttonbar. All the other styles are taken into account. Why this happens, what am I doing wrong and how to correct it?

在我的ASP.NET生成的页面的一个不相关的旁注DTD，以及我的小提琴是XHTML1.0

On an unrelated sidenote DTD of my ASP.NET generated page as well as my fiddle is XHTMl1.0

推荐答案

有在你的CSS一些无效字符关闭大括号之后。您code编辑只是没有显示它们。尝试在网页浏览器，然后打开Web检查器（F12）。切换到资源或来源选项卡，然后看看你的CSS。你会明白我的意思。

There are some invalid characters in your CSS after the closing curly braces. Your code editor just isn't showing them. Try the page in Chrome, then open the web inspector (F12). Switch to the "Resources" or "Sources" tab and take a look at your CSS. You'll see what I mean.

下面是固定的CSS：
