我正在使用Bootstrap。如何让三根柱子都一样高呢?
下面是问题的截图。我希望蓝色和红色的列和黄色的列一样高。
代码如下:
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid">
<div class="row">
<div class="col-xs-4 panel" style="background-color: red">
some content
</div>
<div class="col-xs-4 panel" style="background-color: yellow">
catz
<img width="100" height="100" src="https://lorempixel.com/100/100/cats/">
</div>
<div class="col-xs-4 panel" style="background-color: blue">
some more content
</div>
</div>
</div>
这是我的方法，我已经使用flex与一些变化的媒体查询。
@media (min-width: 0px) and (max-width: 767px) {
.fsi-row-xs-level {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
}
}
@media (min-width: 768px) and (max-width: 991px) {
.fsi-row-sm-level {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
}
}
@media (min-width: 992px) and (max-width: 1199px) {
.fsi-row-md-level {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
}
}
@media (min-width: 1200px) {
.fsi-row-lg-level {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
}
}
然后将所需的类添加到父类中。
<div class="row fsi-row-lg-level fsi-row-md-level">
<div class="col-sm-4">column 1</div>
<div class="col-sm-4">column 2</div>
<div class="col-sm-4">column 3</div>
</div>
我使用响应式断点，因为流量通常会阻碍引导标准响应特性。

<div class="p-2 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Flex item</div>
</div>
之前的一些答案解释了如何使div具有相同的高度，但问题是，当宽度太窄时，div不会堆叠，因此你可以实现他们的答案与一个额外的部分。对于每一个，你可以使用这里给出的CSS名称，除了你使用的行类，所以如果你总是想让div彼此相邻，div应该是这样的:
<div class="row row-eq-height-xs">Your Content Here</div>
对于所有屏幕:
.row-eq-height-xs {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
flex-direction: row;
}
当你想使用sm时:
.row-eq-height-sm {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
flex-direction: column;
}
@media (min-width:768px) {
.row-eq-height-sm {
flex-direction: row;
}
}
当你想要md时:
.row-eq-height-md {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
flex-direction: column;
}
@media (min-width:992px) {
.row-eq-height-md {
flex-direction: row;
}
}
当你想使用lg时:
.row-eq-height-lg {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
flex-direction: column;
}
@media (min-width:1200px) {
.row-eq-height-md {
flex-direction: row;
}
}
编辑
根据评论，确实有一个更简单的解决方案，但你需要确保从所有尺寸的最大所需宽度到xs(例如<div class="col-md-3 col-sm-4 col-xs-12">:
.row-eq-height {
display: -webkit-box;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
flex-direction: row;
flex-wrap: wrap;
}
