这是一个我正在研究的非常简单的条形图,
<div id="container"> <div style="display:inline-block;"> </div> <div style="display:inline-block;"> </div> <div style="display:inline-block;"> </div> </div>
如果我将容器设置为relative,则将内部div设置为absolute&底部：0,然后它们都重叠.它们在没有绝对定位的情况下很好地流动,但条形图是颠倒的.
注意：我的意图是保留条形的内联流,而不必明确指定水平位置.
这是问题的一个更好的例子.

1) correct orientation but vertical alignment is top
<div id="no-content" class="container">
<div class="a"></div>
<div class="b"></div>
<div class="c"></div>
</div>
2) wrong orientation,vertical alignment top
<div id="has-content" class="container">
<div class="a">a</div>
<div class="b">b</div>
<div class="c">c</div>
</div>
3) mixed orientation,alignment is crazy
<div id="mixed" class="container">
<div class="a">a</div>
<div class="b">b</div>
<div class="c"></div>
</div>
4) correct orientation and correct alignment but<br/>
flow has been lost and horizontal position must be explicit
<div id="absolute" class="container">
<div class="a">a</div>
<div class="b">b</div>
<div class="c"></div>
</div>
5) here we go!
<table class="container">
<tr>
<td><div class="a">a</div></td>
<td><div class="b">b</div></td>
<td><div class="c"></div></td>
</tr>
</table>
CSS
body {padding:1em;font-family:sans-serif;font-size:small;}
.container {
height:2.5em;width:50%;margin-bottom:1em;
background-color:lightgray;
font-size:larger;
font-weight:bold;
text-transform:Uppercase;
}
div.container > div {
width:32%;
display:inline-block;
background-color:black;
color:cyan;
}
#absolute { position:relative;}
#absolute > div {position:absolute;bottom:0px;opacity:.3;}
.a {height:50%;}
.b {height:60%}
.c {height:80%;}
td{width:33.333%;vertical-align:bottom;}
td > div{background-color:black;color:cyan;}
解决方法
绝对定位时适合我：
<style type='text/css'>
#container{
position :relative;
border :1px solid #000;
height :60px;
width :100px;
}
.b{
position:absolute;
width :20px;
bottom :0
}
.b1{background:blue ;height:10px; left:0px}
.b2{background:red ;height:30px; left:30px;}
.b3{background:yellow;height:50px; left:60px}
</style>
<div id="container">
<div class='b b1'></div>
<div class='b b2'></div>
<div class='b b3'></div>
</div>
