微信字体大小改变导致H5页面布局错乱，如何解决?

iOS系统禁止微信客户端修改字体大小：

 body {
      -webkit-text-size-adjust: 100% !important;
      text-size-adjust: 100% !important;
      -moz-text-size-adjust: 100% !important;
    }

Android 则通过js 调整：

  <script>
    (function () {
      if (typeof WeixinJSBridge == "object" && typeof WeixinJSBridge.invoke == "function") {
        handleFontSize();
      } else {
        if (document.addEventListener) {
          document.addEventListener("WeixinJSBridgeReady", handleFontSize, false);
        } else if (document.attachEvent) {
          document.attachEvent("WeixinJSBridgeReady", handleFontSize);
          document.attachEvent("onWeixinJSBridgeReady", handleFontSize);
        }
      }
      function handleFontSize() {
        WeixinJSBridge.invoke('setFontSizeCallback', { 'fontSize': 0 });
        WeixinJSBridge.on('menu:setfont', function () {
          WeixinJSBridge.invoke('setFontSizeCallback', { 'fontSize': 0 });
        });
      }
    })();
  </script>
