CSS tab tabs

The CSS Tab tab is said to be implemented in 2 ways

1. Target CSS3

2. A stroke.

The core principle of 2 is to use the stroke to display the problem (stroke parent overflow).

 <style> body,div,ul,li{margin:0; padding:0; font-size:12px;}            . tab_ul{margin:10px Auto 0;            padding-left:20px;            width:228px;            height:31px;            border:1px solid #DBA4E8;        border-bottom:0;}        .
