CSS3创建圆角三角形元素

Question

我只知道圆边的方式.无法弄清楚如何创建这种无图像ul li标签.如你所见,它不完全是三角形:它的顶部和底部有点圆润.是否可以使用css3创建与下图最相似的内容？如果有,怎么样？

先感谢您!

标记:

首先,你必须定义你的化妆如下:

<menu type=list>
    <li>home</li> 
    <li>work</li>  
</menu>

然后使用skew,rotate,box-shadow,border-radius和CSS Pseudo-elements,如下所示:

    width: 32px;
    border-radius: 4px;
    background-color: red;
    top: 11px;
    -webkit-transform: rotate(45deg) skew(16deg,16deg);
    -moz-transform: rotate(45deg) skew(16deg,16deg);
    transform: rotate(45deg) skew(16deg,16deg);
