I've got the following problem:
I want to have a relative container element that contains some child elements each with margin.
If i dont set the height of the container, it resizes height / width by its containing children.
Problem is that it seems to ignore the margin on them.
here some code:
css:
.container{
position:relative;
}
.child {
position:relative;
float:left;
width:200px;
height:50px;
margin-bottom:20px;
}
html:
<div class="container">
<div class="child">hello world</div>
</div>
The container should now resize height to 50+20 = 70px,
so if i put another element below it should be ok but it isn't.
Margin seems not to resize containers height, how to change this?
Not getting your question quiet well but you are probably missing to clear your floats...
Demo
.container{
position:relative;
border: 1px solid #f00;
overflow: hidden;
}
Alternatively you can also use clear: both;
Demo
Depending on the effect you are trying to achieve, either:
1) Add 'overflow:hidden' to the .container div
or
2) Use padding-bottom instead of margin-bottom on the .child div

Take a look at my snippet.
The parent div has a scrollbar and a child div.
Why is the padding (5px) missing on the right side?
#moh
{
background:red;
overflow-x:auto;
width:100px;
padding:5px; // this padding should be on all 4 sides
}
#moh div
{
width:500px;
height:50px;
background:green;
}
<div id="moh">
<div></div>
</div>
To get the bounty I want to know the reason for the missing padding. Maybe there is a name for this phenomenon. Or may it be a browser bug?
It would be excellent to know the part in the CSS or HTML specification which is responsible for the missing padding. But this is not required to get the bounty (Because I know it's hard to find).
#moh
{
background:red;
overflow-x:auto;
width:100px;
padding:5px;
}
#moh div
{
/* width:500px; */
height:50px;
background:green;
}
<html>
<head>
</head>
<body>
<div id="moh">
<div></div>
</div>
</html>
The padding on the right hand side doesn't appear because, the total width of the parent div is 100px(width) + 10px(padding) while the width for the chid div is explicitly set to 500px.
Since the chid div is a block level element and width property greater than that of the parent, it will move past the parent element and hide the right border from the parent div.
Solutions
either remove the width attribute in the child div (so it will take full width of the parent)
or set the width of the parent to at least 500px which is the width of the child element
The reason for this can tell. It's hard to explain, but I'll try. Your" moh " div width value is 100px," moh " in the div width value is 500px. The order of items on Pages is normally left to right. If you do not apply overflow, you see the overflowing sections :
#moh {
background: red;
width: 100px;
padding: 5px; // this padding should be on all 4 sides
}
#moh div {
width: 500px;
height: 50px;
background: green;
}
<div id="moh">
<div></div>
</div>
As you can see, there's an overflow from left to right. when you give overflow, The Overflow will be hidden automatically. So where's the overflow ? (left ? right ? ) That's why it will try to hide everything from the overflow, that is, the part that goes out when it doesn't fit. The part he's trying to hide is in the padding, so that part doesn't show up.
I'm sorry if I said anything that would be misunderstood. Maybe I helped you understand a little bit.
It happens because #moh is 100px and the inner div is 500px. The solution is to set them both to 500px and wrap them with a 3rd div that is limited to 100px with overflow-x.
#wrapper {
overflow-x: auto;
width: 100px;
}
#moh {
background: red;
width: 500px;
padding: 5px; // this padding should be on all 4 sides
}
#moh div {
width: 500px;
height: 50px;
background: green;
}
<div id="wrapper">
<div id="moh">
<div></div>
</div>
</div>
#wrap
{
overflow-x:auto;
width:100px;
}
#inner
{
background:red;
padding: 15px;
width: 500px;
}
#inner div
{
width:500px;
height:100px;
background:green;
}
<div id="wrap">
<div id="inner">
<div></div>
</div>
</div>
one solution would be this:
I had to add some more HTML but hope it solves your problem
It's because of the html behavior of block element like DIV and css overflow property.
By default html elements flow from left to right.
Browsers by Default behavior is -
If parent DIV have any width property (or specific width
inherited) and no css overflow rule is defined, and if child DIV
have defined width which is more than the parent can accommodate,
then it will overflow and will grow beyond the right edge of parent.
To control how Parent Div will deal with overflowing, css overflow
property can be used. overflow:hidden will instruct browser to crop
the exceeding width div at the edge.
overflow-x:auto will instruct browser that, when child element
exceeded width beyond the edge then add scrollbar at x-axis.
So, in the example case above, the child div is having greater width than parent and it is exceeding of the parent. And parent div is having 'overflow-x:auto' rule defined, the scrollbar is appearing upto the edge of parent.
Since padding is inside the edge of the div, it does not considered.
If you want to have padding on all side of the parent div.
Treat the parent div as a grandparent by adding one more div inside a parent and moving child div in it.
On grandparent div you can add required padding and width.
3 On new parent set width:100% which will expand to fit in a grandparent and setting overflow-x:autorule will add scrollbar when the child div expand beyond the parent width.
So, the code will be something like -
#moh
{
background:red;
width:100px;
padding:5px; // this padding should be on all 4 sides
}
#moh div
{
width:500px;
height:50px;
background:green;
}
div{
box-sizing:border-box;
}
#moh div.moh-container{
width:100%;
overflow-x:auto;
}
<!-- Grand parent Div for padding and width -->
<div id="moh">
<!-- Parent Div width 100% to fit in grandparent and overflow rule -->
<div class='moh-container'>
<!-- child element with exceeding width -->
<div></div>
</div>
</div>
Fiddle -
https://jsfiddle.net/guruling/471ka569/13/
This is my CSS code:
#outer {
width:580px;
padding:10px;
float:left;
}
.inner {
width:560px;
padding: 10px;
background-color:#fff;
color:#666666;
}
And the HTML:
<div id="outer">
<div class="inner">
... a lot of content
</div>
</div>
My problem is the background-color for the inner div doesn't extend to fill the entire div alongside its content. I've had this problem quite often, and my solution has usually been to specify a height for #inner, which makes the background fill #inner accordingly. However, I don't want to specify a height explicitly because it's dynamic content. What should I do to make the background-color fill the div as it extends?
Set the position of each element, with the inner element needing to be absolute, and then just tell the inner div to always fill the outer one with height: 100%. The only care that you have to take with this is that setting the position of inner to absolute will then make it ignore floats, but presumably you are taking care of that with outer.
(I changed the background color to red in this answer to make it more obvious what is going on.)
This is my CSS code:
#outer {
position: relative;
width:960px;
height: 500px;
}
.inner {
position:absolute;
height:100%;
width:400px;
background-color: red;
}
And the HTML:
<div id="outer">
<div class="inner">
... a lot of content
</div>
</div>
I couldn't replicate your issue. If you don't specify a height for '.inner', the background color should extend dynamically as '.inner' fills with content.
You might be having an issue due to a lack of a CSS reset. Each browser has a set of standard css rules it applies to all pages, unless you override these rules.
I recommend adding a CSS reset in your above all your current css.
A very basic but popular reset is by Eric Meyer, found here: http://meyerweb.com/eric/tools/css/reset/
Let me know if that helps, and if not try posting an image of what you are experiencing.
Btw, this is how your code renders for me:
The padding of the outer element will always show the background color of the outer element...
Just remove the padding there.
#outer {
width:580px;
/* padding: 10px;*/
background:red;
border:1px solid green;
}
.inner {
width:560px;
padding: 10px;
background-color:lightblue;
color:#666666;
}
i use this code
<div class="main">
<div class="babyOne">
</div>
<div class="babyTwo">
</div>
</div>
.main{
width:100%;
position:relative;
}
.babyOne,.badyTwo{
width:50%;
float:left;
}
with this CSS above everything works fine.
but as soon as i give padding to inner divs all the ui breaks,
.babyOne,.badyTwo{
width:50%;
float:left;
padding:5px;
}
and fire bug shows the increase in the width of divs equal to padding.
According to padding property this should not happen.
any idea how to prevent this?
First of all you need to learn CSS box-model
This states that whatever padding, border, margin you add to you element does count outside it, so for example the element is of 200px width and 100px height, if you add padding say 5px than the width and height will be 205px and 105px respectively, so inorder to workaround with this you need to use CSS3 box-sizing property, but as still it is CSS3 property and if IE is the main thing you want to supprt, I suggest you to resize the elements according to your needs
So for example a div with these styles
div {
height: 100px;
width: 200px;
padding: 5px;
}
You can re-size the above as
div {
height: 95px;
width: 195px;
padding: 5px;
}
CSS3 box-sizing Reference
The WRAPPER must have fixed size: http://jsfiddle.net/esVgH/1 example:
.main{
width:200px;
position:relative;
}
Another solution is display the .baby as a table cell:
.babyOne, .badyTwo {
display: table-cell;
}
Your problem is the expected behaviour.You set a width and then you say give it some padding.So the width plus the padding is going to be greater than the original width.
You can try CSS3s box-sizing attribute: http://www.quirksmode.org/css/box.html
I'm not sure how widely supported it is though.
There's also a host of SO answers here: How apply padding in HTML without increasing the div size?
.babyOne,.badyTwo{
width:45%; /* As you have like based on padding */
float:left;
padding:5px;
}
I made this:
HTML:
<body>
<div id="header" >
</div>
<div id="main" >
</div>
<div id="footer" >
</div>
</body>
CSS:
body
{
margin:0px;
}
#header
{
width:100%;
background-color:black;
height:60px;
}
#main
{
width:300px;
border:1px dotted black;
margin:0 auto;
}
#footer
{
width:100%;
background-color:black;
height:40px;
position:absolute;
bottom:0px;
}
http://jsfiddle.net/VpwQQ/2/
But as you can see, the main div doesn't have a height.
Then I replaced my css by that:
body
{
margin:0px;
}
#header
{
width:100%;
background-color:black;
height:60px;
}
#main
{
width:300px;
border:1px dotted black;
position:absolute;
margin:0 auto;
bottom:60px;
top:80px;
}
#footer
{
width:100%;
background-color:black;
height:40px;
position:absolute;
bottom:0px;
}
http://jsfiddle.net/VpwQQ/1/
But then, the horizontal center doesn't work.
How can I do this design (div centered and that takes all the page in height between the header and footer with a 20 px magin) ?
I'm not sure what you're trying to do, but I'll give my explaination of what's going to happen with your code:
Your #main div doesn't have a height because it doesn't have a height CSS property, nor does it have any content.
You should add either a height: 100px or just add some content and you will see it gets a height.
The reason why I ask what you want to do is because you're not very clear as to what you want your final product to look like.
You're going to have another problem with the footer. If you use position absolute it sticks to the bottom at the moment. Set the height of the #main div to something ridiculously high and you'll see that when you have to scroll down the page the footer stays where it is. See http://jsfiddle.net/VpwQQ/3/
You should use position: fixed but this will keep it on the bottom of the WINDOW and not the DOCUMENT. So then you get into the problem of having to use Javascript in order to measure the document height and setting positions appropriately. Not sure what you're trying to do, but if you're just trying to lay out a website then use standard relative positioning to push the footer down naturally below the #main div.
Edit:
See http://jsfiddle.net/VpwQQ/4/ if you're just trying to set up a normal website layout.
If you want the footer to "stick" to the bottom of the page all the time then you will need to use position: fixed but I don't think this works across all browsers. See http://jsfiddle.net/VpwQQ/6/
Lastly, to get both footer and header to "stick" see http://jsfiddle.net/VpwQQ/8/
I added a div inside #main.
Main now has a 100% width.
Inside, put a div of 300px, with no absolute position.
I forked your fiddle: http://jsfiddle.net/8U9P6/
Personnally I prefer the javascript solution and not using the absolute position. But this solution seems to work.
Add and overflow to contain the content in the inside div: http://jsfiddle.net/M2nZc/
Note that the page will not grow as it is absolute position.
You can't use automatic margins on an absolutely positioned element, as it's not in the document flow any more.
Use width: 100% on the #main div, then put another element inside it that you center using automatic margins.
Demo: http://jsfiddle.net/Guffa/VpwQQ/9/
Note: You may need to use height: 100% on the body and html elements for the bottom sizing to work on the #main element.
Once you fill your #main div with content, it will automatically gain height according to the content. You can simply fill it with a few paragraphs of lorem ispum to simulate content. You can now remove the absolute position and positioning CSS.
Centering a div using the "0 auto" shorthand only works when the parent element (which, for the #main div, is the body element) has a defined width. To do this, try giving your body element a width of 100%. Doing this is something that you might want to make a habit of in you CSS.
To have your #main div always be 20px below the #header div, simply add 20px of margin-bottom to your #header div. Do the same below the #main div to space the footer.
Summed up (without the footer at the bottom, for now) your CSS might read something like this:
body {
width: 100%
margin: 0px;
}
#header {
width: 100%;
height: 60px;
margin-bottom: 20px; /*here we space the header 20px from the next element*/
background-color: black;
}
#main {
width: 300px;
margin: 0 auto 20px auto; /*we append the margin to include 20px of spacing at the bottom*/
border:1px dotted black;
}
#footer {
width:100%;
height:40px;
background-color:black;
}
Example: http://jsfiddle.net/WEx3j/
If you want the footer to be 'sticky' (always be at the very bottom of your website), I advise you to employ this method.
I hope this clarified a few things.
You can see the fiddle here: http://jsfiddle.net/easeS/4/
Here is the html/css I have:
#main div
{
float:left;
width:30px;
margin-right:10px;
}
#main
{
overflow:hidden;
width:100px;
height:50px;
border:1px solid;
}
<div id="main">
<div>test1</div>
<div>test2</div>
<div>test3</div>
</div>
I'm not sure why but it bumps the third div down to a new line instead of hiding it. Any suggestions?
The 3rd div bumps down because there's not enough space for it to float.
Your 3 divs added up together (inc. margin) is equals to 120px;
The wrapper (#main) is 100px.
Therefore bumping the 3rd div down.
If I understood your question correctly...
What you want to do is hide it the 3rd div, for you to do this, you'd need to:
Add another wrapper div and give it a bigger width. Have a look at my example here
No need to add extra wrapping divs...
Try this instead:
#main div
{
display:inline;
width:30px;
margin-right:10px;
}
#main
{
overflow:hidden;
width:100px;
height:50px;
border:1px solid;
white-space: nowrap;
}
Just changed the float rule to display: inline on the divs and added white-space: nowrap to #main.
Is because your divs in your div#main are confined only to those dimensions specified in the style of div#main. To float to infinity and beyond, they need to have a space where to float. You can wrap your divs in a container with a very high height.
Try with this demo.
