Suppose you have   lt body gt     lt div id  root    gt   lt  body gt    With normal CSS  you can do the following  See a working app https   github com onmyway133 Lyrics blob master index html   root     position  absolute    top  0    left  0    height  100     width  100       With flexbox  you can  html  body     height  100    body     display  flex    align-items  stretch      root     width  100

Simply add height  100   onto the  B2 styling  min-height shouldn t be necessary

B2 container position relative  Top position B2   of remaining height  Height of B2   height B1 or remaining height

What suited my purpose was to create a div that was always bounded within the overall browser window by a fixed amount   What worked  at least on firefox  was this   lt div style  position  absolute  top  127px  left  75px right  75px  bottom  50px   gt   Insofar as the actual window is not forced into scrolling  the div preserves its boundaries to the window edge during all re-sizing   Hope this saves someone some time

I d solve it with a javascript solution  jQUery  if the sizes can vary   window setTimeout function            document  ready function              var ResizeTarget       B             ResizeTarget resize function                  var target       B2                target css  height   ResizeTarget height                trigger  resize                500
