在我的网站上，有一个包含内容和文本编辑器的主列，还有一个带有更多文本的侧边栏。有时，侧栏文本无法到达文本编辑器所在的位置。在这种情况下，我想增加文本编辑器所在的div的宽度。如何在不更改页面的整个结构的情况下执行此操作？
来自我的网站的Here's an example page，其中文本编辑器可以更广泛。相关代码嵌入在下面。
<html>

<body>
<div class="row-fluid">
<div class="span2">
<p>sidebar text. this text varies in length and may not reach editor area.
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
</div>
<div class="span9">
<div>
This is where main content goes. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?

<h3>Main Editor</h3>
<p>This is the main editing area. It would be good to widen this area iff there's no text in the sidebar next to it.

请检查这个小提琴：http://jsfiddle.net/D2RLR/6845/。虽然您已经提到过您不想改变整个结构，但您可以通过对结构进行一些调整同时保持响应性来轻松实现您的需求。这就是新HTML应该如何：

我基本上做的是删除了<div>的{{1}}类，其中span9类包含在第<div>个类<row-fluid>中。
