移动自适应
1 <script> 2 //计算根节点HTML的字体大小 3 function resizeRoot(){ 4 var deviceWidth = document.documentElement.clientWidth, 5 num = 750, 6 num1 = num / 100; 7 if(deviceWidth > num){ 8 deviceWidth = num; 9 } 10 document.documentElement.style.fontSize = deviceWidth / num1 + "px"; 11 } 12 //根节点HTML的字体大小初始化 13 resizeRoot(); 14 15 window.onresize = function(){ 16 resizeRoot(); 17 }; 18 </script>
在实现的过程中，要注意父元素和子元素的一些样式，比如在父元素中设置box-sizing: border-box; 可以减少一些问题。
