目的: 重新设置我们页面的样式 (去掉每个浏览自己默认的样式, 将页面初始化为统一样式) 有益于页面的布局, 建议每个页面都重置样式
我们在项目前期准备时都会准备好一个 reset.CSS, 因为不同浏览器对标签的解析各不相同, 重置 css 样式可以让标签在不同浏览器下产生相同的效果(清楚浏览器本身所带的默认样式). 所以一个好的重置样式表是非常重要的. 用过很多网上现成的样式重置表, 然后有时写的样式代码没问题却达不到自己要的效果, 查了才发现是掉进 reset.css 的坑里. 这里推荐用过多种 reset.css 感觉是最好用的重置样式表: Sandal, 这个样式表的好处是他绝大多数的保留了标签的常用效果, 并不是简单粗暴的全部掩杀. 具体样式如下, 可以直接整个复制在自己的 reset.css 中:
- html {

基本的样式重置就这些, 剩下自定义的就自己往里面添加. 这份样式表放在这里方便以后自己使用, 也希望能帮到有需要的你们.
如有不足请多多指教!
