css里面的那个*是什么意思?
<!DOCTYPEhtml><html><head><style>.descendants*{display:block;border:2pxsolidlightgrey...
<!DOCTYPE html>
<html>
<head>
<style>
.descendants *
{
display: block;
border: 2px solid lightgrey;
color: lightgrey;
padding: 5px;
margin: 15px;
}
</style>
<script src="/jquery/jquery-1.11.1.min.js">
</script>
<script>
$(document).ready(function(){
$("div").children().css({"color":"red","border":"2px solid red"});
});
</script>
</head>
<body>
<div class="descendants" style="width:500px;">div (当前元素)
<p>p (子)
<span>span (孙)</span>
</p>
<p>p (child)
<span>span (孙)</span>
</p>
</div>
</body>
</html>
那个 .descendats 后面的 星号是代表全部吗?为何div没有边框,而p元素就有边框? 展开
