重置 reset.css
由于考虑到重置样式会存在潜在的问题，例如我们在全局将strong变成了一个普通标记，在用户可编辑内容区域的strong就不会反应出效果来，用户就会产生很大的疑惑，为什么在编辑器中加粗了字体儿实际上显示出来的效果却没反应呢？
所以，为了注重各个浏览器表现、w3c标准、用户体验以及减小开发难度，我们推荐使用下面这套重置方案：
代码语言：javascript复制@charset "utf-8";
html {font-size:62.5%}
body {font:12px/1.5 tahoma,arial,simsun,sans-serif; font-size:1.2rem; color:#282828}
body,p,blockquote,ul,ol,dl,dd,form,caption {margin:0;padding:0}
ul,ol,p {margin-bottom:1em}
li ul,li ol {margin:0}

blockquote {margin:0 40px 1em}
