Background image is longer than the enclosing div - css

On a customer website, I have to add a background image for only a contained region of the page (its real content part).
The problem is, if the content is short enough, then the image will be clipped. How would be possible to have the image completely visible? I have tried to add the "overflow" CSS attribute but unfortunately it did not help me.
Here is an example of the website I have to work on: http://www.sfp-pensioen.nl/werknemer/welkom The background image is on the div element with id="content".
On the specific link that I am sending it is not an issue because the content is long enough, but if you remove elements using firebug then the problem will become obvious.
ps: IE6 must be supported.

Following on from Graham's answer:
"height" in ie6 acts like "min-height" across other browsers.
min-height: 50px;
_height: 50px;
The example above will provide a cross browser minimum height of 50px. ie6 will read "_height" where other browsers will not. If you don't hacks, use a conditional statement.
Rich

you could either give a height to the id #content
or
apply the background:url("/images/Doelgroep-Background-Image.jpg") no-repeat scroll left top transparent; to #mainContent instead of #content

overflow for background-images is impossible, but you could set a min-height for content (or set the image in another div with lower z-index and position it abolutely to appear at the place you want - but thats a very bad solution)

The overflow attribute controls what happens to the div when the content is too big to fit - if you have a fixed-size div with some content that might overflow, you generally want the auto option. overflow has no effect on a background image.
For your case, it sounds like you want to specify a min-height on the content div. Note that this isn't supported by older browsers like IE6, which you may or may not care about. There are plenty of ways to work around this, though.

What you want is the 100% height you can achieve this with the following.
html {
height: 100%;
}
body {
height: 100%;
}
#content {
height: 100%;
}
You need the min-height and the body needs a height so every child element of the body will follow the rule.
Also by adding min-height: 100%; to all css rules will solve all your problems for any grade A browser.

If you know the #sidebar or #main will always have a visual height the same or larger than the background image then you can simply add the background image to:
.sub #wrapper #mainContent {
background:url("/images/Doelgroep-Background-Image.jpg") no-repeat scroll 0 150px transparent;
}
instead of where it is an the moment on #content

Centering a Modal for IE9 with a transparent background, why need position relative?

The back story....
I'm creating a modal directive for AngularJS that should take any** content and display it centered in the page with a grey transparent background. Sounds like it should be simple. It was working fine until testing w/ IE9 which is the only browser we need to support. Its an in-house site. I have a fiddler working with it centered both vertically and horizontally, that probably could be cleaned up a little. I'm assuming that its going to work, I'm on a mac right now.
The modal's html needs to be in the footer which is fixed to the bottom of the page. So
So I have two questions.
1st- When I was setting up the grey transparent background found that I needed so set the position as relative. Why is this needed? fiddler
.dialogbox-wrapper{
z-index:1000;
display: table-cell;
vertical-align: middle;
/* When this isnt included this has the opacity */
position:relative;
}
2nd- We are using less and CSS3. Is there a cleaner way?
Here's what I need -
Before anyone suggests !doctype HTML, its there.
As to #1
For z-index to be honored, an element must have position of some kind. If position: relative is simply removed, then the default static position does not recognize the z-index: 1000 and so the gray box's z-index: 50 puts your "background" to the foreground.
As to #2
"Cleaner" can be so relative. Here is a modified version of your fiddle that centers it without the need for the min-width (which you expressed in your notations wanting to eliminate), by using display: inline-block with the container set to text-align: center (which is reset on the element itself). It also sets the <a> element for the "close" to display: block so that your width: 200px actually does something (an anchor is an inline element normally, which does not honor width). Of course, now 200px for the .row is driving the width of the modal display.
It all works in IE9 for me.

How can I stop a css background resizing to fit the browser window?

When using a css background such as in the footer on the page below (in the elements div.footer_head and div.footer_footer), if the browser window is resized to less than about 1000px the divs themselves remain at the full width but scrolling right in the browser causes whitespace to appear where the background should be.
I was sure I'd find a similar question on here but can't seem to word it correctly enough to find it in search.
If someone could point me in the right direction I'm sure I can figure this out.
Look at how the divs with class footer_head and footer_footer behave when you resize the browser to be quite thin and scroll to the right.
screenshot http://printanomics.unbranded-nomads.co.uk/picture-2.jpg
You need to add a min-width:1000px to .footer-container.
.footer-container {
float: left;
line-height: 1.5;
margin-top: 20px;
width: 100%;
min-width: 1000px; /* add this */
}
This will mean the smallest width the .footer-container will get is 1000px. Though after that it will expand to 100%.
If you have a look at your css file you will see that the footer width is set to 100% and not 1000px as the other divs. This also applies to your background as your background won't be bigger than the div itself.
I don't know if you use this, but Firebug is a very good Firefox plugin to identify troubles in CSS files.

div width in css

i have a div on a web page that basically acts as a panel container. i want it to:
have a minimum width of 1000px; So no matter how small the content inside the div is, it will at least keep the panel to 1000px in width:
in terms of max width, it should keep going as big as the content within it. So if a person has a 24 inch monitor and they want to maximize the browser it should keep growing until the content inside doesn't have any scroll bars and then stop.
needs to work in all browsers.
how would i do this in css?
Assuming this item is a block element (i.e. "display: block"), it should scale automatically as wide as its containing element (in this case the browser window).
In CSS, just specify "min-width: 1000px." This will work in IE8+ and all modern browsers.
try this
#panel {
min-width: 1000px;
diplay: block;
overflow: hidden; }
Try this:
#panel
{
/* Other styles */
min-width:1000px;
/*width:100%; - removed as it will create horizontal scrollbar if margin and padding aren't 0 as per Josh's comment.*/
}
However, you will problems with older browsers like IE6 which do not like the min-width thingy in which case you will need to use JavaScript.

Background image lost when scroll with browser window resize. Need help to fix

I have a weird problem. The background image (black stripes) in the main container breaks up when the browser window is resized smaller and the user/viewer scrolls up and down (in Safari). The stripes stop stretching down 100%.
#mother {width: 100%; min-height: 100%;height: auto !important; height: 100%; margin: 0 auto; background: url('/img/bg.png') repeat-y center;}
link text
The way to change this horizontally is to set a min-width declaration on the div. Mid-width 100% doesn't work, you need a pixel value.
I don't seem able to duplicate your problem in Safari (or any other browser) vertically - the stripes don't reach the bottom of the page even on first load.
Quite Tricky :)
body { display: table; width:100%}
I'm not aware of a way of directly changing this behaviour myself. Firefox is the same, I think, at least horizontally.
Does it make any difference if you apply the background image to an element that contains #mother? Depending on your page, perhaps you could apply it to the body.

Seeking CSS Browser compatibility information for setting width using left and right

Here's a question that's been haunting me for a year now. The root question is how do I set the size of an element relative to its parent so that it is inset by N pixels from every edge? Setting the width would be nice, but you don't know the width of the parent, and you want the elements to resize with the window. (You don't want to use percents because you need a specific number of pixels.)
Edit
I also need to prevent the content (or lack of content) from stretching or shrinking both elements. First answer I got was to use padding on the parent, which would work great. I want the parent to be exactly 25% wide, and exactly the same height as the browser client area, without the child being able to push it and get a scroll bar.
/Edit
I tried solving this problem using {top:Npx;left:Npx;bottom:Npx;right:Npx;} but it only works in certain browsers.
I could potentially write some javascript with jquery to fix all elements with every page resize, but I'm not real happy with that solution. (What if I want the top offset by 10px but the bottom only 5px? It gets complicated.)
What I'd like to know is either how to solve this in a cross-browser way, or some list of browsers which allow the easy CSS solution. Maybe someone out there has a trick that makes this easy.
The The CSS Box model might provide insight for you, but my guess is that you're not going to achieve pixel-perfect layout with CSS alone.
If I understand correctly, you want the parent to be 25% wide and exactly the height of the browser display area. Then you want the child to be 25% - 2n pixels wide and 100%-2n pixels in height with n pixels surrounding the child. No current CSS specification includes support these types of calculations (although IE5, IE6, and IE7 have non-standard support for CSS expressions and IE8 is dropping support for CSS expressions in IE8-standards mode).
You can force the parent to 100% of the browser area and 25% wide, but you cannot stretch the child's height to pixel perfection with this...
<style type="text/css">
html { height: 100%; }
body { font: normal 11px verdana; height: 100%; }
#one { background-color:gray; float:left; height:100%; padding:5px; width:25%; }
#two { height: 100%; background-color:pink;}
</style>
</head>
<body>
<div id="one">
<div id="two">
<p>content ... content ... content</p>
</div>
</div>
...but a horizontal scrollbar will appear. Also, if the content is squeezed, the parent background will not extend past 100%. This is perhaps the padding example you presented in the question itself.
You can achieve the illusion that you're seeking through images and additional divs, but CSS alone, I don't believe, can achieve pixel perfection with that height requirement in place.
If you are only concerned with horizontal spacing, then you can make all child block elements within a parent block element "inset" by a certain amount by giving the parent element padding. You can make a single child block element within a parent block element "inset" by giving the element margins. If you use the latter approach, you may need to set a border or slight padding on the parent element to prevent margin collapsing.
If you are concerned with vertical spacing as well, then you need to use positioning. The parent element needs to be positioned; if you don't want to move it anywhere, then use position: relative and don't bother setting top or left; it will remain where it is. Then you use absolute positioning on the child element, and set top, right, bottom and left relative to the edges of the parent element.
For example:
#outer {
width: 10em;
height: 10em;
background: red;
position: relative;
}
#inner {
background: white;
position: absolute;
top: 1em;
left: 1em;
right: 1em;
bottom: 1em;
}
If you want to avoid content from expanding the width of an element, then you should use the overflow property, for example, overflow: auto.
Simply apply some padding to the parent element, and no width on the child element. Assuming they're both display:block, that should work fine.
Or go the other way around: set the margin of the child-element.
Floatutorial is a great resource for stuff like this.
Try this:
.parent {padding:Npx; display:block;}
.child {width:100%; display:block;}
It should have an Npx space on all sides, stretching to fill the parent element.
EDIT:
Of course, on the parent, you could also use
{padding-top:Mpx; padding-bottom:Npx; padding-right:Xpx; padding-left:Ypx;}
