Set div height equal to screen size

Question

I have a div element in twitter-bootstrap which will have content that will overflow vertically outside the screen.

I would like the div to take the height of the size of the browser window and let the rest of the content scroll vertically within the window.

I have a sample that is not working @jsFiddle

#content {
    border: 1px solid #000;
    overflow-y:auto;
    height:100%;
}

<div class="container-fluid">
    <div class="row-fluid">
        <div class="span3">Side Bar</div>

        <div class="span9" id="content">
            Content Bar Example Content
        </div>
    </div>
</div>

I am posting this question after reading so questions like SO Questions

EDIT--

Sorry guys I guess I got my question wrong.

What I would like is that my div must fill the rest of the vertical space in the screen.

It would be great if someone can suggest a responsive solution

Answer 1

Using CSS {height: 100%;} matches the height of the parent. This could be anything, meaning smaller or bigger than the screen. Using {height: 100vh;} matches the height of the viewport.

.container {
    height: 100vh;
    overflow: auto;
}

According to Mozilla's official documents, 1vh is:

Equal to 1% of the height of the viewport's initial containing block.
