CSS Reset，意为重置默认样式。HTML中绝大部分标签元素在网页显示中都有一个默认属性值，通常为了避免重复定义元素样式，需要进行重置默认样式（CSS Reset）。

实现方式有很多，根据自己的项目需要，更多的是自己编写适合自己项目的CSS Reset，下面给一些其他大型项目的例子，作为参考。  
1、 **- 以下是CSS Reset 2.0标准：**

/* http://meyerweb.com/eric/tools/css/reset/ v2.0 | 20110126 License: none (public domain) */ html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed, figure, figcaption, footer, header, hgroup, menu, nav, output, ruby, section, summary, time, mark, audio, video { margin: 0; padding: 0; border: 0; font-size: 100%; font: inherit; vertical-align: baseline; } /* HTML5 display-role reset for older browsers */ article, aside, details, figcaption, figure, footer, header, hgroup, menu, nav, section { display: block; } body { line-height: 1; } ol, ul { list-style: none; } blockquote, q { quotes: none; } blockquote:before, blockquote:after, q:before, q:after { content: ''; content: none; } table { border-collapse: collapse; border-spacing: 0; }

如下是一些常用的自定义的共通样式：

/* 自定义的共通样式 */ /* custom */ a { color: #7e8c8d; text-decoration: none; -webkit-backface-visibility: hidden; } li { list-style: none; } html, body { width: 100%; } body { -webkit-text-size-adjust: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); }
