像Twitter对话界面那样设计内部滚动条？

The scroll bar can be seen in the side-panel when you click on a tweet and the conversation linked to the tweet is long enough.

当您点击推文时，可以在侧面板中看到滚动条，并且链接到推文的会话足够长。

How is the scroll bar created and styled?

滚动条是如何创建和设置的？

They're using ::-webkit-scrollbar and the associated pseudo-elements, which only work in WebKit browsers (which is fine, because this is just aesthetics).

他们使用:: - webkit-scrollbar和相关的伪元素，这些元素只适用于WebKit浏览器（这很好，因为这只是美学）。

I've taken the CSS that Twitter is using, see: http://jsbin.com/ubasew

我采用了Twitter正在使用的CSS，请参阅：http：//jsbin.com/ubasew

#doc ::-webkit-scrollbar{width:9px;height:9px;}
#doc ::-webkit-scrollbar-button:start:decrement,#doc ::-webkit-scrollbar-button:end:increment{display:block;height:0;background-color:transparent;}
#doc ::-webkit-scrollbar-track-piece{background-color:#FAFAFA;-webkit-border-radius:0;-webkit-border-bottom-right-radius:8px;-webkit-border-bottom-left-radius:8px;}
#doc ::-webkit-scrollbar-thumb:vertical{height:50px;background-color:#999;-webkit-border-radius:8px;}
#doc ::-webkit-scrollbar-thumb:horizontal{width:50px;background-color:#999;-webkit-border-radius:8px;}

The #doc is as Twitter had it, and it's there so that only scrollbars inside #doc are customised.

#doc就像Twitter一样，它就在那里，只有#doc里面的滚动条才能被定制。

I believe they are using a jQuery plugin or one created by themselves, either way it's something similar to jScrollPane

我相信他们正在使用jQuery插件或者自己创建的插件，无论哪种方式都类似于jScrollPane
