css - 响应式背景，其高度基于使用 Bootstrap 的相邻列

Question

我怎样才能在一个列中有一个完整的图像背景，但不知道它的高度？我正在使用 bootstrap，我需要图像能够响应。请看image为了更好的理解

<div class="  col-xs-12 col-sm-5 col-md-5 col-lg-4 bgimage">
 </div>
 <div class="   col-xs-12 col-sm-7 col-md-7 col-lg-8">
</div>
with .bgimage
{
 background-image: url(../img/user.jpg);

    background-size: cover;

}

Answer 1

这是一个包含 background-size:cover

的列的 Bootstrap 示例

.bgimage{
    background-image: url(http://oi58.tinypic.com/2u9mo0g.jpg);
    background-size: cover;
    height:200px
}
.right{
    background:yellow;
    height:100%;
}
.row{
    background:tomato
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet"/>
<div class='row'>
<div class="  col-sm-5 col-md-5 col-lg-4 bgimage">
    </div>
    <div class="right col-sm-7 col-md-7 col-lg-8">
