每条样式声明后面都加上那个分号。
理由：复制起来方便。

改成「理由：可维护性更好，在最后一行添加新的声明时如果忘记了分号会导致语法错误。」

避免使用 ID 选择器。

如果可以确定是全站唯一的节点，可以使用 ID 选择器，比如典型的 header，footer。通常表单元素也可以使用 ID 选择器。

0 值的单位建议省略，但不强制。

规范中除了 <length>外的取值都不可以省略 0 值后面的单位，WebKit/Blink 可以省略，但这是 Bug。所以书写规范中，不建议推荐省略，应该交给 CSS 压缩工具或者处理器来处理。https://twitter.com/tabatkins/status/676297504237879296
