s-1.rem自适应

head里

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

 

<script>    

    (function(doc,win){ 

            var docEl = doc.documentElement; 

            function recalc(){ 

                docEl.style.fontSize = 100* ((docEl.clientWidth > 640 ? 640 : docEl.clientWidth) / 640) + "px"; 

            } 

            resizeEvt = "orientationchange" in window ? "orientationchange" : "resize"; 

            win.addEventListener(resizeEvt, recalc, false);recalc(); 

        })(document,window); 

</script>

 

*{margin:0;padding:0;}

flex弹性布局不兼容 用float

1rem=100px
