How can I make a DIV occupy the entire vertical space of the page?

Question

How can I make a DIV occupy the entire vertical space of the page?

I am working on a Google Maps application that takes up the majority of the screen. However, I need to reserve a strip at the top for a menu bar. How can I ensure that the map div fills the remaining vertical space without being pushed past the bottom of the page when using height: 100%? I want to achieve a layout like this:

+--------------------------------+
|      Menu Bar (n units tall)    |
|================================|
|              ^                 |
|              |                 |
|             div                |
| (Height: 100%-n units)         |
|              |                 |
|              v                 |

Answer №1

If you want to control the positioning of elements on a webpage, consider using absolute positioning.

HTML Code Example

<div id="content">
    <div id="header">
        Header
    </div>
    This is where the content starts.
</div>

CSS Code Example

BODY {
    margin: 0;
    padding: 0;
}
#content {
    border: 3px solid #971111;
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    background-color: #DDD;
    padding-top: 85px;
}
#header {
    border: 2px solid #279895;
    background-color: #FFF;
    height: 75px;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
}

By utilizing absolute positioning for #content and defining the top, right, bottom, and left properties, you can create a div that covers the entire viewport.

Make sure to set the padding-top of #content to be equal to or greater than the height of #header.

Additionally, nest #header within #content and position it absolutely with specified top, left, right, and height values.

It's important to verify browser compatibility when using this method. For more details, refer to this informative article on A List Apart.

To tackle this problem, one can utilize JavaScript to keep track of the onload and onresize events and adjust the size of the div dynamically:

If utilizing jQuery:

function adjustSize() {
    $("#container").height($(document).height() - $('#header').height());
}

If using plain JavaScript:

function adjustSize() {
    document.getElementById("container").style.height = (document.body.clientHeight - headerHeight) + "px";
}

Edit: Subsequently, these should be attached to the window object.

There is an alternative solution that utilizes CSS3 instead of JavaScript. The calc() function can be used to achieve the same outcome:

HTML

<div id="content">
    <div id="header">
        Header
    </div>
    <div id="bottom">
        Bottom
    </div>
</div>

CSS3

#content {
    height: 300px;
    border-style: solid;
    border-color: blue;
    box-sizing: border-box;
}
#header {
    background-color: red;
    height: 30px;
}
#bottom {
    height: calc(100% - 30px);
    background-color: green;
}

For reference, here is the jsfiddle

It may also be beneficial to explore using the box-sizing: border-box style for inner divs as it can solve issues related to padding and borders extending beyond parent divs.

By determining the page position of the div element, you can resize it without requiring information about the header element:

function adjustSize() {
    var container = $("#box");
    container.height($(document).height() - container.offset().top);
}
