ID 选择器比属性选择器明确度高，class 选择器比任何数量的元素选择器明确度高。尽量使用 ID 选择器来提高明确度。有时候我们可能会想方设法给一个元素应用一条CSS规则，但用尽方法也不能如愿。这种情况有可能是因为我们使用的选择器比另外一个的明确度低，所以明确度高的另一个选择器里的属性就比我们想应用的选择器优先了。这种情况在更大或更复杂的样式表里更为常见。在小一些的项目里，通常这不是大问题。
/* Equivalent to 13px font-size and 20px line-height, but only if the browser default text size is 16px. */#selector {font-size: 0.813em;
line-height: 1.25em;
}

我们推荐慎重使用 Cufon ，因为如果应用到大量的文本上，它会产生很多开销。访问 Cufon Wiki 可以获取更多相关信息。

http头部的 Expires 必须设为据现在一个月到一年（远期）之间的值。缓存只适用于那个指定的URL，所以文件名或任何资源的改变都会产生一个新的拷贝。很多开发者使用build过程来给它们的资源增加一个版本号或时间戳。每个随后的build会开始一个全新的缓存版本，让你在使用远期缓存日期时无需担心。 Google 的这篇文章里有更多关于浏览器缓存的细节信息。
A great code editor can spark productivity in exceptional ways. Many developers prefer rudimentary text editors, others prefer powerful integraded development environments (IDEs). What follows is a general listing of some of the more well-known tools, it would be impossible to list them all.

e TextEditor
E is a new text editor for Windows, with powerful editing features and quite a few unique abilities.

Features column selections, recordable macros, snippets, auto-pairing of brackets and other characters, clipboard history, code folding, tab-triggers, tabbed placeholders and mirror typing. And that’s just for starters. Anything that can be done via scripts through the Mac command line can be done through custom commands, allowing an extremely high degree of customization and expansion of the feature set.
