CSS

.snippet-wrap {position:relative; width:640px;}
.snippet-wrap li { text-shadow:none;}
.snippet-wrap .snippet-num {list-style:none;counter-reset:paragraph;}
.snippet-wrap .snippet-num li {color:#333;border-left:1px solid #BDC3C7;margin-left:22px;}

添加-webkit-user-select: none;

到您的.snippet-wrap .snippet-num li:before CSS，以便：

.snippet-wrap .snippet-num li:before {
  -webkit-user-select: none;

  /* rest of your CSS properties */ 
  ....
}
