1.为什么用rem

根据屏幕大小,自动调整大小

2.如何使用rem

分以下几步

a.用ps把设置稿弄成640px或者750px的(记得等比例缩放)

b.调试时记得把浏览器默认最小字体设置为最小。手机端是支持12px以下的字体的

c.引入meta头

    <meta name="viewport" content="width=device-width,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no,minimal-ui">

d.引入reset文件

(function(doc, win) {
var docEl = doc.documentElement,
resizeEvt = ‘orientationchange‘ in window ? ‘orientationchange‘ : ‘resize‘,
recalc = function() {
var clientWidth = docEl.clientWidth;
if (!clientWidth) return;
if (clientWidth >= 750) {
docEl.style.fontSize = ‘100px‘;
} else {
docEl.style.fontSize = 100 * (clientWidth / 750) + ‘px‘;
}
};
if (!doc.addEventListener) return;
win.addEventListener(resizeEvt, recalc, false);
doc.addEventListener(‘DOMContentLoaded‘, recalc, false);
})(document, window);

  

f.直接在750px或640px的情况下切图,单位也直接用px

g.到http://www.520ued.com/把px转为rem,html的字体大小填100px。

H.收工!!
