[html] How to stretch div height to fill parent div - CSS

I have a page with divs like below

<div id="container">
    <div id="A"></div>
    <div id="B">
        <div id="B1"></div>
        <div id="B2">B2</div>
    </div>
    <div id="C"></div>
    <div id="D"></div>
</div>

with styling as;

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 {
    margin-top: -35px;
    bottom: 0;
    background-color: #FFFFFF;
    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;
}

I want to adjust the height of div B2 to fill (or stretch to) entire div B (marked with a green border) and don't want to cross footer div D. Here is a working fiddle demo(updated). How can I solve this??

This question is related to html css

The answer is


Simply add height: 100%; onto the #B2 styling. min-height shouldn't be necessary.

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;
}

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);

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

<div style="position: absolute; top: 127px; left: 75px;right: 75px; bottom: 50px;">

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.


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

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

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%
}

B2 container position relative

Top position B2 + of remaining height

Height of B2 + height B1 or remaining height
