CSS box stretch to occupy all available room
So I'm trying to create this layout.
Here is a picture of the 3 "boxes" that constitute the page: https://dl.dropbox.com/u/9699560/layout.jpg
And here is my attempt: https://dl.dropbox.com/u/9699560/map.html
The red box is a Google Map, so if its height isn't specified, it shrinks to zero. What I am trying to do is the following:
The green box is fixed width, fixed height. The blue box should occupy 20% of the vertical height of the page, with a maximum height of 100px. The red box should occupy all of the remaining vertical space.
If anyone can figure that out, I'd like to go a little farther, such that when the browser window is expanded vertically and the blue box's top reaches the level of the green box's bottom, it expands left to occupy 100% of the page width.
I've tried floats, absolute, and relative positioning and I c开发者_C百科annot get this to work with pure CSS. If I have to, I will use JavaScript, but I would like to avoid that unless it's the only option.
Thanks!
Here's an attempt (remove comments if you use it):
html, body {
margin: 0;
padding: 0;
height: 100%;
}
#nav {
position: relative;
width: 200px;
height: 400px;
background-color: green;
}
#map {
position: absolute;
top: 0;
left: 200px;
right: 0;
height: 80%; // If #footer is 200px, should occupy all available space
background-color: red;
}
#footer {
position: absolute;
left: 200px; // Should "become" 0 when window height pulls it past #nav
right: 0;
bottom: 0;
height: 20%;
max-height: 100px;
background-color: blue;
}
and the HTML
<html>
<head></head>
<body>
<div id="nav"></div>
<div id="map"></div>
<div id="footer"></div>
</body>
</html>
In my opinion, you will need JavaScript to implement this.
My starting point would probably be from this markup, maybe implement the min/max height behaviors in an event handler that fires on resize :
CSS
html, body { margin: 0; padding: 0; }
#nav { background-color:green; width: 200px; height: 400px; float:left; }
#map { background-color:red; height: 80%; margin-left: 200px; }
#footer { background-color: blue; height:20%; }
HTML
<div id="nav">nav content</div>
<div id="map">map content</div>
<div id="footer">footer content</div>
