Why not ajust border-width and bottom position of <code>.DropMenu:before</code> and <code>.DropMenu:after</code> to bypass the inconsistent behavior of <code>z-index</code>?

<pre class="lang-css prettyprint-override"><code>.DropMenu:before {
 border-color: transparent;
 border-color: rgba(40,54,44,.99) rgba(40,54,44,.99) transparent transparent;
 left: -1px;
 bottom: -12px;
}

.DropMenu:before, .DropMenu:after {
 content: "";
 position: absolute;
 border-style: solid;
 border-width: 6px;
}

.DropMenu:after {
 border-color: transparent;
 border-color: rgba(40,54,44,.99) transparent transparent rgba(40,54,44,.99);
 right: 0;
 bottom: -12px;
}
</code></pre>

PS. The pseudo class <code>:before</code>, <code>:after</code> are not likely supported by lower version of IE.

There is an error on that page which is like this 

<pre><code> TypeError: Cannot read property 'msie' of undefined 
</code></pre>

And because you are using Jquery 1.9.1 this error is obvious. <code>$.browser</code> have been <a href="http://jquery.com/upgrade-guide/1.9/#jquery-browser-removed" rel="nofollow">removed from 1.9</a>. You can use <a href="https://github.com/jquery/jquery-migrate/" rel="nofollow">jQuery Migrate</a> to have <code>$.browser support</code>.

The error is in this <a href="http://tradingvega.com/analyses/wp-content/themes/skeleton/javascripts/jquery.formalize.min.js?ver=1.2.3" rel="nofollow">js file</a>.

I saw where you made mistake....please do following to make it work perfect in everybrowser:

1) Remove your ribbon img from body.

2) Make a new class: 

.topbg{float:left; width:100%; height:25px; z-index:9999; background: url(../images/border_top.png) repeat-x top center; position:fixed;}

3) Put this new class in your HTML:
 
 
 and your content
 

Hope this helps.....

I added a navigation bar (ribbon style) to a website that I'm currently working on and used the jQuery Sticky Plugin to make it make it fixed to the top of the viewport when the user scrolls.

It works perfectly in Firefox, but Chrome disregards the z-index of the sides of the ribbon as soon as the bar sticks. I have spent the last 7 hours googling for a solution to this. I've tried a range of different recommendations including un-nesting the bar and setting positions and z-index values manually for all elements, but to no avail. In fact, I ended up starting from scratch because I had only made it worse trying to fix it.

Could anyone please tell me what I should change to fix the sides of the ribbon when scrolling in Chrome?

我添加了一个导航栏(带状样式)到我目前正在工作的网站，并使用jQuery粘滞插件，使它固定在顶部的视区时，用户滚动。它在Firefox中工作得很好，但Chrome在条形图一粘住就忽略了色带边上的z索引。我花了7个小时在谷歌上寻找这个问题的解决方案。我尝试了一系列不同的建议，包括取消嵌套条形图和手动设置所有元素的位置和z...
