如何在列中创建完整的图像背景但不知道它的高度？我使用bootstrap，我需要图像响应。 请查看image以获得更好的理解
<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;
}

使用body {
font-family: sans-serif;
background-color: lightseagreen;
margin 0;
}
#widget-container {
display: flex;
position: fixed;
top: 30px;
right: 0;
bottom: 0;
left: 0;
}
.widget {
margin: 15px;
background-color: white;
flex-grow: 1;
border: solid 1px black;
}
.widget-prio {
flex-grow: 3;
}
.widget-header {
padding: 10px 0;
width: 100%;
text-align: center;
background-color: skyblue;
}
.widget-content-container {
display: flex;
background-color: lightgrey;
padding: 5px;
}
.widget-textblock {
flex-grow: 1;
text-align: center;
}
.widget-textblock-prio {
flex-grow: 3;
}
将覆盖此框而不会丢失比率。
使用background-size: cover;将填充此框但会丢失比率。
修改
这是背景如何运作的示例。
background-size: 100%;.table {
display: table;
width: 100%;
}
.cell {
display: table-cell;
}
.cell.left {
background-image: url(http://oi58.tinypic.com/2u9mo0g.jpg);
background-size: cover;
}
.cell.right {
width: 60%;
padding: 80px 30px;
background: #ccc;
}
