这取决于你想做什么。来看看SO。它是固定宽度的，非常棒。事实上，如果它是流动的，它就有点像PITA。有些网站使用动态布局会更好看，但就我个人而言，我会选择固定布局，除非你有充分的理由使用动态布局。

最重要的是考虑您的网站或应用程序的主要用例。你希望人们只在移动设备上使用它吗?手机、上网本、台式机?

看看Ethan Marcotte的“响应式Web设计”:http://www.alistapart.com/articles/responsive-web-design/

这是一篇很棒的文章，展示了使用媒体查询实现真正流畅的布局。有时需要为不同的用户代理构建单独的前端，但有时媒体查询是跨不同用户代理提供多种分辨率的完美工具。

是的。页面缩放很棒，但它主要用于使文本变大，而不是使文本填充视口。当然，如果正文文本已经太宽了，缩小它以适应通常会使它无法阅读。

你需要液体布局，如果你想让文本适合视口，无论它是否被放大。

The point about ‘long lines being hard to read’ is often overstated by designers trying to justify fixed width designs(*), but in reality it doesn't seem to hold quite as strongly on-screen as it did on paper. Of course setting a good leading/line-height is important, and max-width can be used to inhibit the worst excesses of long lines. (Set it in font-relative em units.) You don't get max-width in IE6, but that's not the disaster it once was. (You can fix it with a little bit of JavaScript if you really care about those guys. I don't.)

(*这对于高度图形化的布局来说确实更少工作。但对于像StackOverflow这样更简单的布局，没有任何理由不采用液体布局。啧啧@SO，嗯!)

I think it's nice to be able to scale well on a user's screen, rather than make the users pan and zoom. In a time when users surf the web from such a wide variety of devices, ranging from smartphones to ultra-mobile PCs, each with its own, possibly non-standard resolution, I think it's important to keep user-experience at a high level when your site is viewed on such screens. Regarding the text length, it could be bounded by a certain ratio, so it would fit nicely within the layout. I think there are also frameworks that may help with writing a site in a fluid manner, and help with coding maintainability.

我是固定< 800px的大粉丝…更窄的列更容易阅读，而且适用于任何地方。也就是说，如果你想做一个展示超文本的网站……提供应用程序前端的网站，我认为完全是另一罐蠕虫…
