Question

我正在构建一个性能至关重要的站点，而且是最重的css选择器

* {
  margin: 0;
  padding: 0;
}

是否有更便宜的方法来删除所有边距和填充而不会失去此选择器提供的便利？

更新：是的，使用经过测试的库是一个好主意，但如果有人能用数据证明“更便宜”，我将不胜感激

Answer 1

尝试以这种方式列出所有元素（更多信息http://meyerweb.com/eric/tools/css/reset/）：

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;
}

Answer 2

是的，选择真正需要更改的元素。这比较便宜，我在我的所有项目中都使用它：

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;
}

Answer 3

看一下像Boilerplatte或Bootstrap这样的框架。它们都在CSS中重置了条目，并且已知会针对性能进行优化。

Answer 4

是的，使用css reset，我这是我用的，你可以根据你将要使用的元素自行制作
