一个简单的浮动配置可以在没有弹性盒的情况下做到这一点:
html,
body {
height: 100%;
margin: 0;
text-align: center;
}
#root {
background-color: blue;
height: 100%;
}
.tray {
box-sizing: border-box;
background-color: red;
border: thin solid black;
}
.tray-top,
.tray-bottom {
height: 48px;
line-height:48px;
clear: both;
}
.tray-left,
.tray-right {
width: 48px;
height: calc(100% - 96px);
float: left;
}
.tray-right {
float: right;
}
/* to align vertically the content */
.tray-left::before,
.tray-right::before {
content:"";
display:inline-block;
height:50%;
}
<div id="root">
<div class="tray tray-top">top</div>
<div class="tray tray-left">left</div>
<div class="tray tray-right">right</div>
<div class="tray tray-bottom">bottom</div>
</div>

CSS-Grid 可以做到这一点:
html {
height: 100%;
}
body {
height: 100%;
margin: 0;
text-align: center;
}
#root {
background-color: blue;
display: grid;
grid-template-columns: auto 1fr auto;
grid-template-rows: auto 1fr auto;
height: 100%;
}
.tray {
box-sizing: border-box;
background-color: red;
border: thin solid black;
}
.tray-top {
height: 48px;
grid-column: 1 / -1;
}
.tray-bottom {
height: 48px;
grid-column: 1 / -1;
}
.tray-left {
width: 48px;
}
.tray-right {
width: 48px;
grid-column:3;
}
<div id="root">
<div class="tray tray-top">top</div>
<div class="tray tray-left">left</div>
<div class="tray tray-right">right</div>
<div class="tray tray-bottom">bottom</div>
</div>
