I've been playing with this code for almost half of the day and I finally decided to pass it on to you. I would like to place three div elements next to each other with the left and right ones surrounding the main one. I would like both of the outer divs to contain only a background image and hence take on the same height as the middle div. I've been playing with solutions from other posts like this, but all of my tries were unsuccessful.

Thanks in advance for your help.
You'll need to add height: 100% to your body and html tags, as well as your div classes:
html {
height: 100%; /* <------------ */
}
body {
text-align: center;
height: 100%; /* <------------ */
}
div#container {
width: 954px;
margin: 0px auto;
height: 100%;
border: 1px solid lime;
overflow: hidden;
position: relative;
}
div#left {
margin: 0px auto;
width: 5px;
border: 1px solid red;
float: left;
display: block;
height: 100%; /* <------------ */
}
div#right {
margin: 0px auto;
width: 5px;
float: left;
border: 1px solid blue;
height: 100%; /* <------------ */
}
div#content {
width: 920px;
margin: 0px auto;
text-align: left;
background: #ffffff;
padding: 0px 10px;
float: left;
height: 100%; /* <------------ */
}
I know this doesn't really answer your question, but I tend to prefer a method that uses position:relative on the parent and position:absolute on the capping elements. This guarantees that a dynamically changing box will not throw off your layout. I also like to use the :before :after attributes (IE 8+) because of semantic reasons, but you can use child elements instead. Works just as fine. I also threw in box-sizing (FF needs -moz syntax) so the borders don't look fugly. (probably not necessary in a production setting as your would be using a background instead).
And now, the code!
CSS
div#container:before {
content:"";
width: 5px;
border: 1px solid red;
display: block;
position:absolute;
height:100%;
left:0px;
top:0px;
box-sizing:border-box; /* careful... FF needs -moz if you need that compatibility */
}
div#container:after {
content:"";
width: 5px;
border: 1px solid blue;
display: block;
position:absolute;
height:100%;
right:0px;
top:0px;
box-sizing:border-box;
}

Media queries can be used to achieve most of what % offers without any of the pain. It's not as smooth but when used for intro banners it is perfectly acceptable.
Using mobile declarations first you would use something like this.
.banner { height: 200px; }
#media all and (min-width: 500px) {
.banner { height: 400px; }
}
#media all and (min-width: 1000px) {
.banner { height: 500px; }
}
Edit: I used min-width but min-height can also be used. To really get things to look good on all sort of devices, a mix of min-width and min-height would need to be used.

At the top level of my website layout are 4 div tags.
The first one is a full width header section, with css:
#header {
margin-top: 0px;
height: 70px;
border: 4px double rgb(255,255,255);
border-radius: 20px;
background: rgb(88,150,183) no-repeat fixed left top;
padding: 0px;
}
At the bottom is a full width footer:
#footer {
clear: both;
margin: 0px;
color:#cdcdcd;
padding: 10px;
text-align: center;
border: 4px double rgb(88,150,183);
border-radius: 20px;
}
On the left is my main menu section:
#categories {
float:left;
width:150px;
border: 4px double rgb(88,150,183);
border-radius: 20px;
}
All of those 3 elements work fine. They're in the right place and that doesn't change whatever screen resolution the user has on their monitor, or whether they view it on not maximum screen size.
My problem is with the main element of the page - where all the interesting stuff is. It's directly to the right of the menu div - or rather, it should be. My css is:
#main {
float:right;
min-height: 440px;
width: 80%;
margin-bottom: 20px;
padding:20px;
border: 4px double rgb(88,150,183);
border-radius: 20px;
}
width 80% works OK for most of my users, but for those with less resolution, the main element shifts below the menu, which is ghastly.
What I would ideally like is for the width set in the css #main to be something like (100% - 170px), thus leaving a nice margin between the menu and the main bit at all times and never pushing it below the menu. However, css standards don't fulfil that desire yet!
Could someone suggest how I amend my css to give me a nice clean page that's clean for all my users? Or do I need to go back to setting out my page using tables?
Using CSS3 flex

#aside{
width: 170px; /* You, be fixed to 170 */
background: #1CEA6E;

}
#main{

width: calc(100% - 170px);
float: left;
padding: 24px;
}
<div id="aside">Aside</div>
<div id="main">Main</div>
Using float: left; and overflow
* { box-sizing: border-box; margin: 0; }
#aside{
width: 170px; /* You, be fixed to 170 */
float: left; /* and floated to the left */
padding: 24px;
background: #1CEA6E;
}
#main {
background: #C0FFEE;
padding: 24px;
overflow: auto; /* don't collapse spaces */
/* or you could use a .clearfix class (Google for it) */
}
<div id="aside">Aside</div>

You can use 'calc' function supported by all modern browsers and IE9+, or switch to flexbox (supported by IE11+)
See this pen: https://codepen.io/neutrico/pen/MyXmxa
width: calc(100% - 170px);
Keep in mind that all borders matter unless you set 'box-sizing' to 'border-box' (or just remove these borders and apply them on child elements).
Before you roll your eyes and move on, I know how to solve this problem by using a fixed height and absolution positioning with top: and bottom:, but I want to solve it without using fixed heights. I want to learn more about CSS so I'm trying to solve this a different way.
I have set up a typical navbar running across the top, and then a scrolling content div below.
However! How do I fit the bottom scrolling div container to the remaining space without using absolute coordinates? I can't do position: absolute, because then I'd need to know the height of the navbar to set "top:". And I can't do "bottom: 0" because I'd have to specify a height.
Here's the JS filddle:
http://jsfiddle.net/8dugffz4/1/
The class of interest is ".result". I currently have the height fixed, which I don't want.
Thanks, y'all.

Here's a solution that uses display: table and can actually achieve fluid heights:
http://jsfiddle.net/8dugffz4/8/
And a minimalistic snippet in case you want to see specifically what I did:
* {
margin: 0;
padding: 0;
}
html,
body {
height: 100%;
}
#table {
display: table;
height: 100%;
width: 100%;
}
#table > div {
display: table-row;
}
#navbar {
height: 45px;
opacity: .5;
}
#navbar > div {
height: 100%;
background: black;
}
#results {
height: 100%;
}
#results > div {
height: 100%;
overflow: auto;
background: green;
}
<div id="table">
<div id="navbar">
<div></div>
</div>
<div id="results">
<div></div>
</div>
</div>
If you're just looking for an alternative to the position: absolute method, you could use the height: 100% method:
html, body { height: 100%; }
body { box-sizing: border-box; padding-top: 45px; }
.navBar { height: 45px; margin-top: -45px; }
.results { height: 100%; }
Like so: http://jsfiddle.net/8dugffz4/7/
Please see http://jsfiddle.net/jr32V/ which contains the following:
CSS:
body {
font-size: 2em;
color: white;
background-color: grey;
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
.topmenu, .main {
width: 500px;
margin: 0 auto;
}
.topmenu {
background-color: red;
}
.main {
background-color: black;
}
.mainpicker {
margin-right: 20px;
float: left;
background-color: green;
}
.maincontent {
width: 600px; /*get rid of this line to see how it should look*/
float: left;
background-color: blue;
}
HTML:
<body>
<div class="topmenu">
A whole bunch of menu stuff
</div>
<div class="main">
<div class="mainpicker">
Picker
</div>
<div class="maincontent">
Content on right of picker
</div>
</div>
</body>
I would like the "maincontent" div to be exactly to the right of "mainpicker", just as it seems if you remove the width attribute on it.
Note that the width attribute is just to illustrate the point, in actual use the width may go beyond the container by any amount.
Also note that I do not want the parent container ("main") to exactly expand, since it must begin at the same left position as "topmenu". i.e. that they both have the same width vis-a-vis centering/margin-auto calculation
I think this is what you are looking for. Add width and margin to your .main class and remove float:left; from your .maincontent class. I updated your fiddle
.main {
background-color: black;
width:500px;
margin:0 auto;
}
.mainpicker {
margin-right: 20px;
float: left;
background-color: green;
width:100px;
}
.maincontent {
width: 600px;
background-color: blue;
}
EDIT:
If you want to float both children you have to stay inside the given width of you parent class. So your code would look like this:
.topmenu {
background-color: red;
width:500px;
margin:0 auto;
}
.main {
width:500px;
margin:0 auto;
}
.mainpicker {
background-color: green;
width:100px;
float:left;
}
.maincontent {
background-color: orange;
width:400px;
float:left;
}

The following code seemed to do the trick, even though the result doesn't look pleasing to the eye.
.mainpicker {
margin-right: 20px;
float: left;
background-color: green;
display: inline-block;
position: relative;
}
.maincontent {
width: 600px;
float: left;
background-color: blue;
display: inline-block;
position: absolute;
width: auto;
}
DEMO: http://jsfiddle.net/thauwa/jr32V/5/
http://jsfiddle.net/jr32V/6/
i put box-sizing: border-box; and width as percentages to mainpicker and maincontent
.mainpicker {
float: left;
background-color: green;
width: 20%;
box-sizing: border-box;
}
.maincontent {
float: left;
background-color: blue;
width: 80%;
box-sizing: border-box;
}
does this help you?
I have the following HTML/CSS:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Test script</title>
<style>
body, div, html {
margin: 0;
padding: 0;
}
.outer {
text-align: center;
}
.inner {
display: inline-block;
margin-top: 20px;
padding-left: 50px;
}
.inner div {
background: red;
border: #00F solid 5px;
box-sizing: border-box;
display: inline-block;
height: 200px;
line-height: 200px;
margin-right: 50px;
text-align: center;
width: 200px;
}
.inner div:hover {
border: #0F0 solid 50px;
}
</style>
</head>
<body>
<div class="outer">
<div class="inner">
<div>1</div>
<div>2</div>
<div>3</div>
<div>4</div>
</div>
</div>
</body>
</html>
What's really strange is that when you mouse over a div, the change in the border size causes the text within the div to be pushed down as well as the other divs to be pushed down as well.
However, if you remove the text from the divs (i.e., "1", "2", "3" and "4"), then the problem does not occur.
Why does the text within the divs cause the layout to break?
Thank you.
If you switch out display:inline-block; with display:block; float:left; it works in safari.
body, div, html {
margin: 0;
padding: 0;
}
.outer {
text-align: center;
}
.inner {
display:block;
margin-top: 20px;
padding-left: 50px;
float:left;
}
.inner div {
background: red;
border: #00F solid 5px;
box-sizing: border-box;
display: block;
height: 200px;
margin-right: 50px;
text-align: center;
width: 200px;
float:left;
line-height: 200px;
}
.inner div:hover {
border: #0F0 solid 50px;
box-sizing: border-box;
}
http://jsfiddle.net/blaird/hFvPT/
I honestly have no idea why.
The problem is your line-height. It is set to 200px which is the same as the height of the box, so when you increase the border to 50px you only have room for 100px. One simple fix is to add the lower line-height number to your hover:
.inner div:hover {
border: #0F0 solid 50px;
line-height: 100px;
}
EDIT
As Barbara Laird has pointed out, this does not actually seem to fix the problem. You could add overflow:hidden to the box and make it work, but it is not pretty. An alternative solution, which also keeps your text vertically centered, would be to add a wrapper and use display:table:
.inner div {
background: red;
border: #00F solid 5px;
box-sizing: border-box;
display: block;
height: 200px;
margin-right: 50px;
text-align: center;
width: 200px;
float: left;
display: table;
}
.inner div span {
display: table-cell;
vertical-align: middle;
}
Here is a working example: http://jsfiddle.net/7JH55/
I'm using this code...
<div id="app">
<div id="app-actionbar">
topbar
</div>
<div id="app-userinfo">
sidebar
</div>
<div id="app-content">
content
</div>
</div>
/** Styling **/
#app {
border:1px solid #666;
}
#app-actionbar {
color: #333;
width: 900px;
float: left;
height: 45px;
background: #D9D9DC;
margin-top:10px;
}
#app-content {
float: left;
color: #333;
background: #FFFFFF;
height: 350px;
width: 725px;
display: inline;
}
#app-userinfo {
color: #333;
background:#F2F2F2;
height: 350px;
width: 175px;
float: left;
}
However, it's not working like I want it to.
I want to add a border around it, but its not working (and its moving the content down).
You need to clear the floated elements in your #app . Try adding overflow:hidden; or overflow:auto; to #app. That will get the border to wrap you entire DIV.
Here's a live jsfiddle link of your above snippets with the overflow:hidden assigned:
http://jsfiddle.net/AhZAU/
The spacing at the top, "(and its moving the content down)", is being created by the margin-top:10px on the #app-actionbar. Remove the margin and the space will no longer be present: http://jsfiddle.net/AhZAU/1/
The QuirksMode Way©:
#app {
border:1px solid #666;
overflow: auto;
width: 100%;
}
http://jsfiddle.net/CePt6/
From the article:
If you want to add, say, a border
around all floats (ie. a border around
the container)...
NOTE
As far as the gap at the top, you can eliminate that by removing margin-top: 10px; from #app-actionbar.
#app-actionbar {
color: #333;
width: 900px;
float: left;
height: 45px;
background: #D9D9DC;
}
http://jsfiddle.net/CePt6/2/
EDIT
Now, if you mean the content block is moving down, make the width of the #app the same width as your #app-actionbar:
#app {
border:1px solid #666;
overflow: auto;
width: 900px;
}
http://jsfiddle.net/CePt6/3/
Just for giggles, tried that but with some layout changes. Check if it helps. (demo here)
<div id="app">
<div id="app-actionbar">
topbar
</div>
<div id="app-userinfo">
sidebar
</div>
<div id="app-content">
content
</div>
</div>
CSS:
#app {
border:1px solid #666;
clear:both;
position:absolute;
}
#app-actionbar {
color: #333;
width: 900px;
float: left;
height: 45px;
background: #D9D9DC;
margin-top:0px;
}
#app-content {
float: left;
color: #333;
background: red;
height: 350px;
width: 725px;
display: inline;
left:200px;
top:75px;
}
#app-userinfo {
color: #333;
background:#F2F2F2;
height: 350px;
width: 175px;
float: left;
top:65px;
}
this should do the trick. jsfiddle.net demo
#app {
border:1px solid #666;
height: auto;
overflow: auto;
width: 900px;
}
#app-actionbar {
color: #333;
width: 900px;
float: left;
height: 45px;
background: #D9D9DC;
}
#app-content {
float: left;
color: #333;
background: #FFFFFF;
height: 350px;
width: 725px;
display: inline;
}
#app-userinfo {
color: #333;
background:#F2F2F2;
height: 350px;
width: 175px;
float: left;
clear: left;
}
Here's what you can do:
Add the following lines to your #app div like this:
width:900px;
min-height: 300px;
overflow:auto;
The above is meant to auto-expand the outer div as the inner contents increase in length.
This however will be a restriction on older versions of IE since they did not have the min-height property.
