解决方法
我相信你正在寻找这样的东西：
blockquote {
font-family: Georgia,serif;
font-size: 18px;
font-style: italic;
width: 500px;
margin: 0.25em 0;
padding: 0.35em 40px;
line-height: 1.45;
position: relative;
color: #383838;
}
blockquote:before {
display: block;
padding-left: 10px;
content: "\201C";
font-size: 80px;
position: absolute;
left: -20px;
top: -20px;
color: #7a7a7a;
}
blockquote cite {
color: #999999;
font-size: 14px;
display: block;
margin-top: 5px;
}
blockquote cite:before {
content: "\2014 \2009";
}
将代码放入JSFiddle for you to play with.
