CSS - 使用CSS实现Mac窗口效果

来不及了，直接贴代码。

HTML代码

<div class="user-bio">
	<div class="user-bio-top">
		<div class="circle-red"></div>
		<div class="circle-yellow"></div>
		<div class="circle-green"></div>
	</div>
	<div class="user-bio-body">
		Wait,i know you<br>
		keep hungry keep foolish<br>
		苍苍之天不可得久视，堂堂之地不可得久履，道此绝矣！<br/>
		告后世及其孙子，忽忽锡锡，恐见故里，毋负天地，<br>
		更亡更在，去如舍庐，下敦闾里！人固当死，慎毋敢佞。
	</div>
</div>

CSS代码

主要是三个圆点
