The concept of floats is probably one of the most unintuitive concepts in CSS. Floats are often misunderstood and blamed for floating all the context around it, causing readability and usability problems. However, the reason for these problems isn’t the theory itself, but the way the theory is interpreted – by developers and browsers.

Float（浮动）概念也许是CSS中最让人迷惑的一个概念吧。Float经常被错误理解，而且因为将上下文元素全部浮动导致的可读性、可用性问题备受责难。然而，这些问题的根源并不在于理论本身，而是开发人员以及浏览器对理论的解读造成的。
Still, if you take a closer look at the float theory, you’ll find out out that it isn’t that complex as it appears to be. Most related problems are caused by the older versions of (take a guess) Internet Explorer. If you know the bugs, you can control the way information is presented in a more sophisticated, profound way.

如果你认真的去读一下浮动概念，你会发现并不像所见的那样复杂。大多数问题都是由于老版本的IE带来的（我只是猜想^_^）。如果你知道这些bug，你就能避免这些问题。

Let’s try to tackle the issue and clarify some usual misunderstandings, which always appear once floats are being used. We’ve browsed through dozens of related articles and selected the most important things you should keep in mind developing css-based layouts with floats.

让我们尝试去解决这些问题并澄清一些以前使用浮动的误解。我们参考了成打的相关文章，并选取了最为重要的一些你必须了解的问题。 Update (01.05.2007): our comment form returns some strange mistakes. We’re working on it. Sorry for inconvenience.

What You Should Know About Floats

你需要了解的关于浮动的一些概念

---

“The practice of flowing text around an image goes back a long, long time. That’s why the ability was added to the Web starting with Netscape 1.1, and why CSS makes it possible using the property float. The term “float” refers to the way in which an element floats to one side and down, as described in the original “Additions to HTML 2.0″ document that accompanied the release of Netscape 1.1.”“关于图文围绕的实践可以追溯到很久很久以前。这也就是为什么从Netscape1.1开始这个功能被引入浏览器，以及为什么CSS使用浮动属性来实现它。‘Float(浮动)’这个术语引用自伴随Netscape1.1一同发布的‘Additions to HTML 2.0’文档，描述一个元素浮动至某一侧并停下的表现方式。”[Containing Floats]

“A floated box is positioned within the normal flow, then taken out of the flow and shifted to the left or right as far as possible. Content may flow along the side of a float. […] When a box is taken out of normal flow, all content that is still within normal flow will ignore it completely and not make space for it.”

“浮动元素的定位还是基于正常的文档流，然后从文档流中抽出并尽可能远的移动至左侧或者右侧。文字内容会围绕在浮动元素周围。当一个元素从正常文档流中抽出后，仍然在文档流中的其他元素将忽略该元素并填补他原先的空间。” [Float Positioning]
