Consider the next code:
#container {
width:500px;
}
#inside {
padding:10px;
width:100%;
}
If I choose width:100%; will it be the same as stating "width 480:px" (that is, calculating the padding already) or will it be as "width:500px"
Thanks

It will be like width:500px and adding the padding it will push the insides of overflow the #container..
But if #inside is a block element, then just giving the padding will make it behave as if it were width:480px
Example at http://www.jsfiddle.net/uA9LV/
It will be the same width as the parent container provided it's a block level element. So #inside will be 500px wide with 10px of padding on every side.
I put this in a sample document and the container div only resized 3 sides (left, top, and bottom).. and the inside div pushed it's boundaries outside of the container by 20px to the right.
I tested in IE8, Firefox 3.6.10, and the latest Chrome. Using various doctypes had no effect.
The code I used was:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Untitled</title>
<style>
#container {
width:500px;
border: solid 1px blue;
}
#inside {
padding:10px;
width:100%;
border: solid 1px red;
}
</style>
</head>
<body>
<div id="container">
<div id="inside">
Hello World!
</div>
</div>
</body>
</html>
Note: if you remove the Width declaration from the #inside div then you'll get exactly what you want. Which is an inner div that is 480px in width + 10px on each side for padding. See this link for more information on it: Solving the CSS Padding problem.

Given the heights I've applied to my div elements I expected everything to line up nicely however it appears that the bottom div is higher than the intended 15% and overlaps onto the middle div, see here demonstrated by the red border at the bottom...
Where am I going wrong? I'm sure it's something simple.
You should understand how the box model works... You are using borders which are counted outside the element, so for example if your element is 200px in height, and has a 5px border, the total element size will be 210px;
So considering this as the concept, what you are having elements which sums up to 100%, and you are using borders too, so that is exceeding the viewport which will result in vertical scroll...
Also you don't have to use position: absolute;, you are making it absolute, just to avoid scrolls but that's a wrong approach. Absolute element is out of the document flow, and will give weird results if you didn't wrapped inside a position: relative; element.
Demo
Few Tips :
Use lowercase tags
Avoid Uppercase ID's unless required
Using 100% vertically is very rare, designers generally use width: 100%; for making the layouts responsive. So if you don't have any specific reason to go for 100% vertical elements, don't go for it..
Solution:
Still if you want to stick with the vertical layout spanning to 100% in height, you should use box-sizing: border-box; property...
What box-sizing will do here?
Well, using the above property, it will change the default behavior of the box-model, so instead of counting the borders, paddings etc outside the element, it will count inside it, thus it will prevent the viewport to be scrolled.
I will provide you an example, which I had made for another answer.
Demo 2 (Updated, had forgot to normalize the CSS)
Explanation for the above demo, if you look at the CSS, I am using
* {
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
}
which will make every element paddings, borders etc to be counted inside the element and not outside, if you mark, am using a border of 5px; and still, the window won't get a scroll bar as the border is counted inside the element and not outside.
There are many things a bit off with your code, however the straight forward answer is that borders are part of the box model, therefore part of the height calculation. So the height of your div is 15% of the height + the width of your borders, thus it is oversized.
Please see this explanation of the box model:
http://css-tricks.com/the-css-box-model/
I think it has to do with your borders (each of which is 5px). Since you have your TopBar, MidBar, and BottomBar have percentage heights that add up to %100, WITH additional borders, you have a problem of having an effective height of greater than %100, and then, because you have BottomBar with an absolute position at the bottom, it doesn't force the page to scroll, but simple induces some overlap between the MidBar and BotomBar divs.
Remove "Position: absolute" from: #BottomBar. That should do the trick.
I am completely new to html and css so my question could be very basic but hope you guys can help me udnerstnad,
I am using following css code
body
{
background-color:Olive;
width:550px;
font-family:Verdana;
}
I am setting width to 550px and as a result all my paragraphs contract to 550px but the background is applied to the whole page even beyond the 550px
I understand that because of inheritance the child elements would have inherited the width property from body, but I was thinking that if I set width property of body to 550px then background should be visible in 550px wide area and not the full page,
I don't get the logic here..
If you apply a color to the html, for example html { background-color: yellow; }, you'll see this is not the case at all. The <body> tag is special in that it is intended to encompass the entire contents of the HTML page. When you apply a background, then, the default is for it to paint the entire background page, unless htmls background has otherwise been set.
See this jsfiddle example. Like the other posters above, I highly recommend using a <div> element to wrap, size, and color your content.
This is described in the CSS2 specifications as so:
The background of the root element becomes the background of the canvas and covers the entire canvas, anchored (for 'background-position') at the same point as it would be if it was painted only for the root element itself. The root element does not paint this background again.
Why not wrap your content in a div, and set the properties to that?
<body>
<div class="content">
... content here
</div>
</body>
and apply the same classes to the div
.content
{
background-color:Olive;
width:550px;
font-family:Verdana;
}
You can use a container div that wraps your whole page and acts like a "fake" body. Then if you apply these style to this div your problem will be solved.
css
#wrapper {
width: 550px;
margin: 0 auto;
text-align: left;
}
HTML:
<body>
<div id="wrapper">
Piece of text inside a 550px width div centered on the page
</div>
</body>
You should try this http://jsfiddle.net/ajaypatel_aj/8tfKc/
HTML
<div id="wrapper">Test me!</div>
CSS
*{
margin:0;
padding:0;
}
body{
text-align:center; /*For IE6 Shenanigans*/
font-family:Verdana;
}
#wrapper{
width:550px;
margin:0 auto;
text-align:left;
background-color:Olive;
}
Answer is simple applied body color will set to whole page you must have to use div .
This is what you are looking for.
<html>

<div id='test'>

Another answer is:

I have a setup requiring a div filling 100% of the screen with a margin of 10px. Inside that, there is a navigation pane at the top followed by a content div below with a padding and an inner content dive with a padding. However, using the 100% height of parent and then adding a margin/padding stretches the div to 100% + margin + padding. Is there a fix for this? I noticed the absolute positioning trick, but that messes up the flow of the other divs if I absolutely position my content div. It also makes the resizing and flow non-liquid. Any way to keep those things and still achieve my goal, preferrably with CSS and not javascript?
Code Below:
ASPX
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Untitled Page</title>
<link rel="Stylesheet" href="test.css" />
</head>
<body>
<div id="wrapper">
<div id="navigation">
</div>
<div id="content">
<div id="inner">
</div>
</div>
</div>
</body>
</html>
CSS
html, body
{
height:100%;
width:100%;
margin:0px;
padding:0px;
background-color:Black;
}
#wrapper
{
height:100%;
margin:10px;
background-color:Blue;
}
#navigation
{
height:100px;
background-color:Green;
}
#content
{
height:100%;
padding:10px;
background-color:Orange;
}
#inner
{
height:100%;
width:100%;
padding:5px;
background-color:Lime;
}
You can try adding box-sizing:border-box onto any elements which you want to have 100% height and padding at the same time.
Works in IE8+ and the good browsers, so browser support is actually quite good
http://css-tricks.com/box-sizing/
You can try two things...
1) changing the height of the wrapper, navigation, content and inner to something like 98%.
2) try adding a transparent 1px solid border to the wrapper and other elements. This often shifts the margin to margin relationship of elements.
Hope this helps
Please note: I am new to CS. Brand new.
I want my button div to be placed horizontally inside the confirm div: example.
Right now my dialog-button div width is equal to the width of the confirm Div. Why?
I am just placing two buttons inside my Div, so it's width should be equal to 128 (the total of two button witdh). Similarly the height should be equal to button height, but it isn't.
Second i want that mt button-div placed center horizontally . I tried left: 50% inside my button-div. But it is aligning the left margin with the centre of the confirm div. How can i do it?
EDIT
--------------------------------------------------
May be I didn't understand correctly, but if you want it inside then put it inside.
<div id="message">
Are you sure you want to
<div id="dialog-button">
<button>Ok</button>
<button>Cancel</button>
</div>
</div>
Demo
Update 1
Right now my dialog-button div width is equal to the width of the confirm Div. Why?
Why, because <div>s are block tag, they always take 100% width of the containing element. It is not equal to the width of confirm Div.
To make the dialog-button take the actual width use display: inline-block as its CSS. Demo
Update 2:
To the best from what i understood. This is what you want. If not help me help you.
Update 3:
Ok, here is a demo with the image. I will leave the without image part to you. ;)
The div which the two buttons are in is actually the width of the of the comfirm div. The reasons why divs stretch to the width of their parent, is because that is block level element.
the reason every thing seems so confusing is that you have a lot left floating divs in your example. These are changing how things would normally laid out. To make things simpler why dont you try removing some of the more confusing elements. I suggest trying a more simple example like the one below:
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link rel="stylesheet" href="css/ie-css3.htc" type="text/css">
<link rel="stylesheet" href="css/messageDialogStyle.css" type="text/css">
<script type="text/javascript" src="js/jquery-1.7.1.js">
</script>
<script type="text/javascript" src="js/jquery-ui-1.8.17.custom.min.js">
</script>
<script type="text/javascript" src="js/puff.js"></script>
<script type="text/javascript" src="js/jquery.dialog.js"></script>
</head>
<body>
<div id="confirm">
<div id="message">
Are you sure you want to
</div>
<div id="dialog-button">
<button>Ok</button>
<button>Cancel</button>
</div>
</div>
</body>
</html>
If you want to center a button. If you change the margin-left and margin-right to auto you will center any block element. try changing your css to the css below:
#confirm {
background-color: #ddd;
display:block;
width:400px;
min-height:120px;
position:absolute;
border:1px solid #ccc;
border-radius: 15px;
-moz-border-radius: 15px; /*FireFox*/
-webkit-border-radius: 15px; /*Opera, safari*/
behavior: url(css/border-radius.htc); /*IE*/
}
#message {
width: 280px;
border:1px solid #ccc;
white-space: normal;
word-wrap: break-word;
margin:20px 0 0 0;
overflow: hidden;
}
#dialog-button {
border:1px solid #ccc;
position: relative;
}
button {
display:block;
margin-left:auto;
margin-right:auto;
width: 64px;
}
Note if you have to make the button a block element for the margin auto trick to work.
You can find more about block level element here.
I've been struggling for days trying to get a page working with CSS and DIVS. Basically I need a masthead with logo/banner ad at the top, then a three column layout (nav, main content and additional side content), then ending the page with a footer.
I will need to set a background color and put a 1 px border around the three content columns so I have a wrapper div around them. And the three columns may also need there own background colors too.
What I am aiming for is to have each of the three content columns be the same height and grow as required. However, if I add a lot of content to one of them, the content spills out below the footer. I've done lots of searches on this and tried various combinations of height and min-height but still can't get it working.

i've used it on various projects and it works extremely well.
There is nothing wrong, content wrapper is 100% of screen, but you have other elements (top, bottom). That means 100% + n px.
Remove header and footer, and you will see for yourself. You should wrap everything in a div, and set height to 100% and overflow:hidden, but this is dangerous.
You also need to add this rule on top, because some elements like body have margin/padding by default.
*{margin:0;padding:0;}
Note that borders add height/width to overall height/width so you will always have vertical scroll even if the border is 1px, thats 100% + 1px
