So, the problem is about collapsed margin.
Follow this example : http://jsfiddle.net/2ausj/
code :
<!DOCTYPE html>
<html lang="fr">
<head>
<title>Page</title>
<meta http-equiv="content-Type" content="text/html; charset=UTF-8" />
<link type="text/css" rel="stylesheet" media="screen, tv, projection" href="css/style.css" />
</head>
<body>
<div id="main">
<div id="home" class="main"></div>
<div class="main"></div>
<p></p>
<div class="main"></div>
<div class="main"></div>
<div class="main"></div>
<div class="main"></div>
<div class="main"></div>
</div>
</body>
</html>
And Css
html { overflow: hidden;}
body {
background: transparent url('../images/background.jpg') repeat;
}
#main { background: blue; padding: 1px; border: 1px;}
.main {
max-width: 1000px;
height: 200px;
background: red;
margin: 50px auto;
position: relative;
position: absolute;
}
p { height: 1px; }
I have some div. Each have a margin top and bottom of 50px in this case but betwen the divs, there is only 50 px margin instead of 100px
I read lot of articles about collapsing margin, all of them say to set padding or border to the parent. I tried to put div directly in body and set padding to the body, i tried to set padding on my div, i tried to puts my div in a container div and set him padding or border, nothing seem to work.
Only solution i found but it's dirty, as you can see in my example, is put an element betwen div with a 1px height. And then, there is finally 100px betwen divs, even 101 because of 1px .
I wish a greater solution, and also understand why nothing i've tried is working.
Please excuse my bad english (Not my fault, i'm french) and thanks in advance :)
Since your first div has an ID as well as a class you could do this:
Change your .main margin to: margin:0 auto 100px auto;
And add the #home ID with a style of margin-top:100px;
I fiddled with the Fiddle for a few and don't understand why the top and bottom margin of 50px isn't working, but what I have provided above will fix your issue. If this works for you please accept it as answered.

Please see the HTML below:
#container
{
height: 60%;
width: 100%;
background-color:green;
}
#floatElement
{
top:0px;
height: 60%;
width: 50%;
background-color:red;
float:right;
}
<html>
<head>
<link rel="stylesheet" href="css.css">
</head>
<body>
<div id="floatElement">
<h1 >this is a test inside the float element</h1>
</div>
<div id="container">
<h1>test</h1>
</div>
</body>
</html>
Here is the result.
Why is there extra space above the first line of text inside the float i.e. why is the word "text" and the words: "this is a test inside a float element" not in line?
I have looked here: https://developer.mozilla.org/en-US/docs/Web/CSS/float. The first image indicates that they should be in line. I have also Googled it and this is the closest I got: How to remove space at top of page when using float?. However, it does not answer my question.
This is because the browser default user agent stylesheet adds style for some elements, in that case I'd recommend using a reset css.
Now back to the question, the space appears because you're using float so it will contain the default margin of the h1. According to https://developer.mozilla.org/
The float CSS property places an element on the left or right side of
its container, allowing text and inline elements to wrap around it.
The element is removed from the normal flow of the page, though still
remaining a part of the flow.
Reference: https://developer.mozilla.org/en-US/docs/Web/CSS/float
Whereas background color of div elements doesn't respect to the margin of its child, you have to use padding for that. Because margin applies outside of the border of the element and padding happens inside the borders.
Here's an example:
#container { height: 60%; width: 100%; background-color:green; }
#container h1 {margin: 100px 0;}
<html>
<head>
<link rel="stylesheet" href="css.css">
</head>
<body>
<div id="container">
<h1>test</h1>
</div>
</body>
</html>
As you can see the margin is omitted by the background color of the parent, but still takes place.
Here's another scenario.
#container { height: 60%; width: 100%; background-color:green; }
#container h1 {margin: 0; padding: 100px 0;}
<html>
<head>
<link rel="stylesheet" href="css.css">
</head>
<body>
<div id="container">
<h1>test</h1>
</div>
</body>
</html>
You can see what happens when padding is added to the h1
Here's the answer for your question, to make them both fly on the same line remove the margin for the h1
#container
{
height: 60%;
width: 100%;
background-color:green;
}
#floatElement
{
top:0px;
height: 60%;
width: 50%;
background-color:red;
float:right;
}
#floatElement h1, #container h1{
margin-block-start: 0;
/*you can also use margin: 0 in short */
}
<html>
<head>
<link rel="stylesheet" href="css.css">
</head>
<body>
<div id="floatElement">
<h1 >this is a test inside the float element</h1>
</div>
<div id="container">
<h1>test</h1>
</div>
</body>
</html>
I have a parent DIV with a child DIV that I'd like to have stretch to the bottom of the parent. At present it does not despite having height:auto!important; A screenshot illustrating the issue can be seen here.
The relevant HTML (as a Jade template) is as follows:
.main.top0
.infoPanel.koneksa_bg_blue
.innerPanel.mtop0.mbottom0
.infoCaption.font8em.koneksa_white 404
.infoCaption.koneksa_white We can't find the page you are looking for
.infoCaption.koneksa_white
| Don't worry. Just try to go back or
a.koneksa_white.underline(href='/') home
.footer.stickyBottom.koneksa_bg_gray.koneksa_fg_light_gray
The main DIV is the parent and the infoPanel is the child (colored in blue in the image above) that I am struggling to stretch.
The corresponding CSS is as follows:
.main {
width:100%;
min-height:700px;
height:auto!important;
overflow: hidden;
z-index: 1;
top:3em;
position: relative;
}
.infoPanel {
width:100%;
height:auto!important;
display: block;
padding:0;
}
.innerPanel {
width:90%;
padding:40px 0;
height:auto!important;
margin:0 5%;
display: block;
}
I'm aware that this is a fairly common question but it seems like the answer is always to include a hard-coded height. I would like to avoid this because while that was a perfectly fine solution for the desktop styling this is intended to be displayed on mobile devices and as such I'd like it to be a bit more responsive than a hard-coded height.
Thanks for any insights that you can provide.

One solution that works in all modern browsers is to do the following:
html, body {
height: 100%
}
.main {
position: absolute;
top: 3em;
bottom: 0;
width: 100%;
}
This seems an unusual solution but modern browsers will actually respect all 4 sides being defined at the same time and stretch the element to match. Here is an example jsFiddle: http://jsfiddle.net/nqt7vqs1/2/
You can do the same with all child elements as well because position: absolute implies position: relative for the purposes of positioning child elements.
If this solution doesn't work, another option is to do the following:
html, body {
height: 100%
}
.main {
position: absolute;
top: 0;
height: 100%;
margin: 3em 0 -3em 0;
overflow: hidden;
}
This is a "hidden margin" trick that also works in all modern browsers. Same Fiddle with these settings: http://jsfiddle.net/nqt7vqs1/3/
I am planning to add colour to the center of the html page. I have tried this:
My html file
<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<div id="v">
</div>
</body>
</html>
My styles.css
#v {
background: red;
position: center;
}
You can set a height and a width to the div and add a margin like this:
#v {
height: 100px;
width: 100px;
background-color: red;
margin: auto;
}
I would assume that you mean to center an element on the page and then add a background color to that element. Your CSS is not valid although you did come close. if you want to add a background then you need to use background-color instead. If you want to center that element then you can adjust the margin of said element here. is an example that may help.
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>center a div and add background color</title>
<style type="text/css">
.wrapper{
width: 100%;
height: 400px;
background-color: blue;
margin: 0 auoto;
}
.centered-element{
width: 50%;
height: 200px;
margin: 0 auto;
background-color: red;
}
p{
text-align: center;
}
</style>
</head>
<body>
<div class="wrapper">
<div class="centered-element">
<p>this div is centered!</p>
</div>
</div>
</body>
</html>
what i have done is gave the div that i wanted to center align a margin of 0 auto; this will center align the div. I hope that helped!
Today I came across this code. It works as I would expect in Chrome, but it is adding a margin on a wrong element with Firefox:
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>Site Title</title>
<style type="text/css" media="screen">
body {
background-color: #aaa;
margin: 0;
}
#header {
background-color: #fff;
}
#logo {
float: left;
}
#menu {
float: right;
}
.container {
width: 960px;
margin: 0 auto;
}
.main {
margin-top: 36px;
}
.clear {
clear: both;
}
</style>
</head>
<body>
<div id="header">
<div class="container">
<div id="logo">Logo</div>
<div id="menu">Home</div>
<div class="clear"></div>
</div>
</div>
<div class="container main">
Content
</div>
</body>
</html>
Firefox seems to add the margin in the .main rule to the content div, which was expected, and to the header div too.
If I add some text inside the header it would work as expected and the header won't have that margin:
<div id="header"> Some text here
<div class="container">
<div id="logo">Logo</div>
<div id="menu">Home</div>
<div class="clear"></div>
</div>
</div>
</div>
I can also add some text after the header block and it would also do the trick for Firefox.
I can't figure out why is Firefox adding that margin to the header element.
Very strange problem, I don't see why this happens.
It however seems to help when you add a padding of at least 1px to .container.
Also check this demo.
The problem has something to do with the container with automatic height and floating children...
Adding display:inline-block; to the #header will make it works in every browser (well except old IE), will include in the white box the right-floated div too (that now is not), and will continue to adjust the height automatically.
Fiddle: http://jsfiddle.net/AndreaLigios/VfAq7/1/
I'm setting up a very simple fixed-liquid layout. The header is set to 100%, the sidebar is set at a fixed width and floated to the left, and the width of the content area is not defined (so that it fills the remaining space).
It works well in every browser except IE, where approximately 3 pixels of white space is added between the sidebar and the content area.
I can't reproduce the problem in JSFiddle (even when I copy and paste my exact code), so I've attached images instead. The first image was rendered in Chrome and the second was rendered in IE9.
CSS (styles.css)
body {
margin: 0px;
}
#header {
width: 100%;
height: 150px;
background: #F00;
}
#sidebar {
float: left;
width: 280px;
height: 1000px;
background: #0F0;
}
#content {
height: 1000px;
background: #00F;
}

Have you tried adding a doctype declaration?
