Take a look at "css speech bubble" the idea is the same: http://nicolasgallagher.com/pure-css-speech-bubbles/demo
看看“css语音气泡”的想法是一样的：http: //nicolasgallagher.com/pure-css-speech-bubbles/demo
You have to mess with pseudo css ::after and ::before (which doesn't work in some IE), and borders to create a square or an triangle that overlapping each other.
您必须使用伪 css ::after 和 ::before（在某些 IE 中不起作用）和边框以创建相互重叠的正方形或三角形。
Example:
例子：
.active::after {
content: "";
position: absolute;
bottom: -15px;
left: 50px;
border-width: 15px 15px 0;
border-style: solid;
border-color: #F3961C transparent;
display: block;
width: 0;
}
Here is an explanation how to create triangle with a box and border: http://www.sitepoint.com/pure-css3-speech-bubbles/
