我遇到的一个问题是要有一个滚动条，一个元素需要指定一个高度（而不是一个百分比）。
诀窍是在每列内嵌套另一组div，并将列父级的显示设置为使用flex-direction：column弯曲。
html, body {
height: 100%;
margin: 0;
padding: 0;
}
body {
overflow-y: hidden;
overflow-x: hidden;
color: white;
}
.base-container {
display: flex;
flex: 1;
flex-direction: column;
width: 100%;
height: 100%;
overflow-y: hidden;
align-items: stretch;
}
.title {
flex: 0 0 50px;
color: black;
}
.container {
flex: 1 1 auto;
display: flex;
flex-direction: column;
}
.container .header {
flex: 0 0 50px;
background-color: red;
}
.container .body {
flex: 1 1 auto;
display: flex;
flex-direction: row;
}
.container .body .left {
display: flex;
flex-direction: column;
flex: 0 0 80px;
background-color: blue;
}
.container .body .left .content,
.container .body .main .content,
.container .body .right .content {
flex: 1 1 auto;
overflow-y: auto;
height: 100px;
}
.container .body .main .content.noscrollbar {
overflow-y: hidden;
}
.container .body .main {
display: flex;
flex-direction: column;
flex: 1 1 auto;
background-color: green;
}
.container .body .right {
display: flex;
flex-direction: column;
flex: 0 0 300px;
background-color: yellow;
color: black;
}
.test {
margin: 5px 5px;
border: 1px solid white;
height: calc(100% - 10px);
}
</style>
