reset.scss 和 global.scss

reset.scss的目的是为了消除不同浏览器默认样式的不一致性

global.scss规定了整个站点的公共样式、公共方法和公共参数

实现px2rem方法，将px转为rem

---------------------------------------------

1.在src/assets/styles中新建reset.scss

/* 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;
	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;
}
html, body {
  width: 100%;
  height: 100%;
  font-family: 'PingFangSC-Light', 'PingFang SC', 'STHeitiSC-Light', 'Helvetica-Light', 'Arial', 'sans-serif';
}

2.新建global.scss(通过px2rem方法，将px转为rem)

@import 'reset';

// 1rem = fontSize px
// 1px = (1 / fontSize)rem
$fontSize: 37.5;
@function px2rem($px) {
  @return ($px / $fontSize) + rem;
}

@mixin center() {
  display: flex;
  justify-content: center;
  align-items: center;
}

3.在main.js中引入global.scss
