文件内容如下

module.exports = {
  "plugins": {
    // to edit target browsers: use "browserlist" field in package.json
    "postcss-pxtorem": {
      rootValue: 100,
      propList: ['*'],
      minPixelValue: 1
    }
  }
}

在index.html中引入配置文件

web配置

<script>
     (function (a, b) {
       // 页面自适应脚本
       var c = a.documentElement,
           d = "orientationchange" in window ? "orientationchange" : "resize",
           e = window.recalc = function () {
             var a = c.clientWidth;
             if (a) {
               var fontsize = Math.floor(100 * (a / 1920));
               if (fontsize < 50) {
                 fontsize = 50;
               }
               if (fontsize >= 100) {
                 fontsize = 100;
               }
               c.style.fontSize = fontsize + "px"
             }
           };
       a.addEventListener && (b.addEventListener(d, e, !1), a.addEventListener("DOMContentLoaded", e, !1));
     })(document, window);
   </script>

移动端配置

<script>
    !function (window) {

      /* 设计图文档宽度 */
      var docWidth = 750;

      var doc = window.document,
        docEl = doc.documentElement,
        resizeEvt = 'orientationchange' in window ? 'orientationchange' : 'resize';

      var recalc = (function refreshRem() {
        var clientWidth = docEl.getBoundingClientRect().width;

        /* 8.55：小于320px不再缩小，11.2：大于420px不再放大 */
        docEl.style.fontSize = Math.max(Math.min(20 * (clientWidth / docWidth), 11.2), 8.55) * 5 + 'px';

        return refreshRem;
      })();

      /* 添加倍屏标识，安卓为1 */
      docEl.setAttribute('data-dpr', window.navigator.appVersion.match(/iphone/gi) ? window.devicePixelRatio : 1);

      if (/iP(hone|od|ad)/.test(window.navigator.userAgent)) {
        /* 添加IOS标识 */
        doc.documentElement.classList.add('ios');
        /* IOS8以上给html添加hairline样式，以便特殊处理 */
        if (parseInt(window.navigator.appVersion.match(/OS (\d+)_(\d+)_?(\d+)?/)[1], 10) >= 8)
          doc.documentElement.classList.add('hairline');
      }

      if (!doc.addEventListener) return;
      window.addEventListener(resizeEvt, recalc, false);
      doc.addEventListener('DOMContentLoaded', recalc, false);

    }(window);

  </script>
