How to stretch div height to fill parent div - CSS

If you're gonna use B2 for styling purposes you can try this "hack"

#B { overflow: hidden;}
#B2 {padding-bottom: 9999px; margin-bottom: -9999px}

Use the "min-height" property
Be wary of paddings, margins and borders :)

html, body {
    margin: 0;
    padding: 0;
    border: 0;
}
#B, #C, #D {
    position: absolute;
}
#A{
    top: 0;
    width: 100%;
    height: 35px;
    background-color: #99CC00;
}
#B {
    top: 35px;
    width: 200px;
    bottom: 35px;
    background-color: #999999;
    z-index:100;
}
#B2 {
    min-height: 100%;
    height: 100%;
    margin-top: -35px;
    bottom: 0;
    background-color: red;
    width: 200px;
    overflow: scroll;
}
#B1 {
    height: 35px;
    width: 35px;
    margin-left: 200px;
    background-color: #CC0066;
}
#C {
    top: 35px;
    left: 200px;
    right: 0;
    bottom: 35px;
    background-color: #CCCCCC;
}
#D {
    bottom: 0;
    width: 100%;
    height: 35px;
    background-color: #3399FF;
}

Suppose you have

<body>
  <div id="root" />
</body>

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%
}
