我有一些像这样的div:
<html>
<body>
<div id="out">
<div id="in">
<div id="one" style="position: relative; z-index: 3">
</div>
<div id="two" style="position: relative; z-index: 2">
</div>
<canvas id="three" style="position: relative; z-index: 1">
</canvas>
<canvas id="four" class="hidden">
</canvas>
</div>
<-- Some more divs with position: static (default)-->
</div>
</body>
</html>
我想要#one (stacked over) #two (stacked over) #three
,但我得到的只是#one (before) #two (before) #three
,就像没有应用和任何z索引一样。如何使我的z-index工作,更重要的是为什么我的代码不起作用?

您必须使用top
和left
属性。看看这个解决方案https://jsfiddle.net/f5L4puaa/
<div id="out">
<div id="in">
<div id="one" style="position: relative; z-index: 3; background-color:orange; top: 3.5em;">div one
</div>
<div id="two" style="position: relative; z-index: 2; background-color: yellow; top:3em;">div two
</div>
<canvas id="three" style="position: relative; z-index: 1; background-color:pink;">div three
</canvas>
<canvas id="four" class="hidden">
</canvas>
</div>
</div>
