<button>在ios系統下點擊出現底色，解決方法：
-webkit-tap-highlight-color:transparent

防止ios系統長按出現別的列表:
-webkit-touch-callout: none; 

禁止複製文字:
-webkit
 
-user-select:none

防止ios滑動卡頓:
-webkit-overflow-scrolling: touch;

初始大小及禁止使用者縮放:
<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,minimum-scale=1,user-scalable=no" />

防止Safari自動識別號碼:
<meta name="format-detection" content="telephone=no" />
