一、CSS重置样式表

郁子大约 5 分钟约 1364 字

专门用来对浏览器的样式进行重置，有以下三种方式：

（一）全局

适用于学习场景，容易造成后续代码重叠，样式重复设置等问题

* {
  margin: 0;
  padding: 0;
}

（二）reset.css

直接去除了浏览器的默认样式【少用】

CSS reset(css 重置)基本上是不需要的，至少可以说 80% 的 CSS reset 都是没有必要的，反而增加了页面
CSS 的重写，尤其像 *{margin:0;} 的做法更是要不得（反而破坏了很多 UI 的兼容性，比如说单复选框等）。
我不是一概鄙弃 CSS reset，有些常用标签我也是会简单重置一下的，而且会避免 overwrite（样式重写），以保证样式最精简，渲染最高效

（三）normalize.css

对默认样式进行了统一【常用】
保留了标签的基本样式，如 li 的列表序号、p 间距等样式
normalize.cssopen in new window

Normalize.css 只是一个很小的 CSS 文件，但它在默认的 HTML 元素样式上提供了跨浏览器的高度一致性
相比于传统的 CSS reset ， Normalize.css 是一种现代的、为 HTML5 准备的优质替代方案
Normalize.css 现在已经被用于 Twitter 、 Bootstrap 、 HTML5 Boilerplate 、 GOV.UK 、 Rdio 、 CSS Tricks 以及许许多多其他框架、工具和网站上
