文字
语法：
E[att|="val"] { sRules }
说明：
选择具有
att属性，其值是以val开头并用连接符"-"分隔的字符串的E元素；如果值仅为val，也将被选择。这样理解会更简单：如果元素E拥有att属性，并且值为val，或者值是以val-开头的，那么E将会被选择。
例如：
<style>
div[class|="a"] {
border: 2px solid #000;
}
</style>
<div class="a">0</div>
<div class="a-test">1</div>
<div class="b-test">2</div>
<div class="c-test">3</div>在这个例子中，前2个div将会被命中：
第1个div，拥有class属性，并且值为a，所以被命中；
第2个div，拥有class属性，值是a开头并紧跟着连接符“-”，所以被命中；
