我想获得下一个布局：
******
div with max-height 80% percents of a screen
------
div with fixed height
------
++++++
div which grows until parent div (marked with *)
is smaller than it's max-height
After parent div have reached max-height,
this div should show vertical scroll.
++++++
******
我用例子创建了jsfiddle。您可以在css中取消注释//max-height:210px;以查看我想要实现的内容。但是在小提琴中我有预定义的页面大小，我可以调整溢出块的高度。我怎么能在页面高度的百分比中做到这一点？
