Question

我有一个高度为100％的弹出式div。

.popup{
height:100%;
}

我已经开始并创造了60％的利润率

.popup{
margin-top:60%;
}

因此弹出窗口底部只有40%空间可用。

在40%底部空间，我希望有一个可滚动的div容器，其高度可能为500px。这不起作用，只有40%空格可用，并且不显示滚动条。

如何500px空间可用40%？

检查此代码段：

body,
html,
.outer {
    width: 100%;
    height: 100%;
}
.wrapper-top, .wrapper-bottom {
    position: relative;
    width: 400px;
    top: 0;
    bottom: 0;
    border: 1px solid #555;
}
.wrapper-top {
    height: 60%;
}
.wrapper-bottom {
    height: 40%;
}
.inner {
    position: absolute;
    width: 100%;
    top: 0px;
    bottom: 0px;
    overflow-y: auto;
}
