Getting inline-block element's height to fill the parent
提问by Brian Genisio
I have a container with two items. One of those items is a selectelement, so I need to set the sizeattribute via HTML. I want the other item in the container to stretch its height to fit the container. I can't figure it out. I don't want to explicitly set the height of the container because I don't know the size of that select box.
我有一个装有两件物品的容器。其中一项是select元素，因此我需要size通过 HTML设置该属性。我希望容器中的另一个项目拉伸其高度以适合容器。我想不通。我不想明确设置容器的高度，因为我不知道该选择框的大小。
.container {
padding: 5px;
border: 1px solid black;
}
.container .column {
display: inline-block;
width: 40%;
background-color: #AAA;
padding: 5px;
margin: 5px;
vertical-align: top;
height: 100%;
}
select {
width: 100%;
}<div class="container">
<div class="column">Stretch to fill?</div>
<div class="column">
<select size="15">
<option>Option 1</option>
<option>Option 2</option>
</select>
</div>

If table-cellis an option, here's a way to do it:
如果table-cell是一个选项，这是一种方法：
.container {
display: table;
width: 100%;
padding: 5px;
border: 1px solid black;
}
.container .column {
display: table-cell;
width: 40%;
background-color: #AAA;
padding: 5px;
border: 5px solid white;
vertical-align: top;
height: 100%;
}
select {
width: 100%;
}<div class="container">
<div class="column">Stretch to fill?</div>
<div class="column">
<select size="15">
<option>Option 1</option>
<option>Option 2</option>
</select>
</div>

If I understand what you are saying, you are facing the 100% height columnsproblem. I'm sorry to tell you there is no actual solution but "hacks".
如果我明白你在说什么，你就面临着100% 高度列的问题。我很遗憾地告诉你，除了“黑客”之外，没有实际的解决方案。
Hereyou can find several of those workarounds. I like to use the one true layout method.
在这里，您可以找到其中几种解决方法。我喜欢使用一种真正的布局方法。
By the way, this is thinking you don't want to use the experimental css3 columns properties.
顺便说一句，这是认为您不想使用实验性的 css3 列属性。

No answers here gave me comfort so I went and search for the truth. I added a bit more css to make a point on the spacing between two boxes.
这里没有答案给我安慰，所以我去寻找真相。我添加了更多的 css 来说明两个框之间的间距。
CSS:
CSS：
.wrapper {
background-color:gray;
}
.container {
margin: 25px auto;
display: inline-flex;
}
.leftbox {
height: inherit;
display: inline-block;
border: 1px solid #D7D2CB;
background-color: #FFFFFF;
border-radius: 5px;
max-width: 550px;
margin-right: 18px;
align-items: stretch;
padding: 15px;
width: 100%;
}
.rightbox {
height: 100%;
display: inline-block;
border: 1px solid #D7D2CB;
background-color: #FFFFFF;
border-radius: 5px;
align-items: stretch;
max-width: 300px;
width: 100%;
padding: 20px 15px;
}
HTML:
HTML：
<div class="wrapper">
<div class="container">
<div class="leftbox">
There is something here, I am not avoiding it.
</div>
<div class="rightbox">
Probably something else here but much much much much much much much much much much much much much much much much much much much much much much much much much much much much much bigger.
