Here is my code:
<style>
#defCalTree
{
overflow: scroll;
overflow-x: hidden;
}
</style>
and
<div class="defCalTree">
<div id="treeboxbox_tree" style="width:80%; height:100%;background-color:#f5f5f5;border :1px solid Silver; "></div>
</div>
and
to the treeboxbox_tree I attach a dhtmlx tree. But, the scroll bar which is shown I think doesn't refer to the tree. If the tree consists of many items, the div is getting bigger. It should remain the same size, and by using the scroll we will get to every item. What am I doing wrong?
In css you are using # which is selector for id and in html you are using class. so how your css will work. is this your problem or some thing else check it.
Try to either:
Amend <div class="defCalTree"> to <div id="defCalTree">
OR
amend #defCalTree to .defCalTree
You need to specify the height of the #defCalTree div. As it is now, it is growing in size to wrap its contents, which is the intended behaviour.

Let´s say I have following mark up and CSS:
HTML:
<div id="Container">
<div id="Content">
[* some text *]
</div>
</div>
CSS:
#Container {
height: 400px;
overflow: scroll;
}
#Content {
height: 800px;
}
Obviously this set up invokes a scrollbar to possibly scroll down 400px. I created a jsFiddle for a better understanding.
Is there a way to jump to the second paragraph by CSS only?
I added a javascript command to demonstrate what I want to achieve. Just uncomment and run it.
There are two things that I have tried so far, but in both cases I was not able to scroll up anymore:
Setting the margin-top attribute of the inner div container to -180px
Setting the inner div container to position: absolute and top: -180px
Note: I do not care for the paragraph or any content. This is just an example. I want to jump to an arbitrary position.
Edit:
Anchor tags are not an option. I do not want to flood my mark up with unnecessary tags.
How about the humble 'a' tag?
jump to one
jump to two
<a name="one">this is one</a>
<a name="two">this is two</a>
Not with CSS, but with standard HTML/anchors.
http://jsfiddle.net/r6vn7/3/
paragraph 2
Give your paragraph an ID and use the URL hash to say where to go to. I used an anchor as an example how to make it jump to the second paragraph.
Alright, I understand that the purpose of a DIV is to contain its inner elements - I didn't want to upset anyone by saying otherwise. However, please consider the following scenario:
My web page (which only takes up a width of 70% of the entire page) is surrounded by a container (a div). However, under my navigation bar which is at the top of the page, I would like to create w banner that takes up 100% of the width of the entire page (which means it will have to extend outside the bounds of its container as the container is only taking up 70% of the page's width).
This is the basic idea that I am trying to accomplish: http://www.petersonassociates.biz/
Does anyone have any suggestions for how I could accomplish this? I'd appreciate any help.

If you just want the background of the element to extend across the whole page this can also be achieved with negative margins.
In a nutshell (correction from comment):
.bleed {
padding-left: 3000px;
margin-left: -3000px;
padding-right: 3000px;
margin-right: -3000px;
}
That gives you horizontal scroll bars which you remove with:
body {overflow-x: hidden; }
There is a guide at http://www.sitepoint.com/css-extend-full-width-bars/.
It might be more semantic to do this with psuedo elements: http://css-tricks.com/full-browser-width-bars/
EDIT (2019):
There is a new trick to get a full bleed using this CSS utility:
width: 100vw;
margin-left: 50%;
transform: translateX(-50%);
I guess all solutions are kind of outdated.
The easiest way to escape the bounds of an element is by adding:
margin-left: calc(~"-50vw + 50%");
margin-right: calc(~"-50vw + 50%");
discussion can be found here and here. There is also a nice solution for the upcoming grid-layouts.
If I understood correctly,
style="width: 100%; position:absolute;"
should achieve what you're going for.
There are a couple of ways you could do this.
Absolute Positioning
Like others have suggested, if you give the element that you want to stretch across the page CSS properties of 100% width and absolute position, it will span the entire width of the page.
However, it will also be situated at the top of the page, probably obscuring your other content, which won't make room for your now 100% content. Absolute positioning removes the element from the document flow, so it will act as though your newly positioned content doesn't exist. Unless you're prepared to calculate exactly where your new element should be and make room for it, this is probably not the best way.
Images: you can also use a collection of images to get at what you want, but good luck updating it or making changes to the height of any part of your page, etc. Again, not great for maintainability.
Nested DIVs
This is how I would suggest you do it. Before we worry about any of the 100% width stuff, I'll first show you how to set up the 70% centered look.
<div class="header">
<div class="center">
// Header content
</div>
</div>
<div class="mainContent">
<div class="center">
// Main content
</div>
</div>
<div class="footer">
<div class="center">
// Footer content
</div>
</div>
With CSS like this:
.center {
width: 70%;
margin: 0 auto;
}
Now you have what appears to be a container around your centered content, when in reality each row of content moving down the page is made up of a containing div, with a semantic and descriptive class (like header, mainContent, etc.), with a "center" class inside of it.
With that set up, making the header appear to "break out of the container div" is as easy as:
.header {
background-color: navy;
}
And the color reaches to the edges of the page. If for some reason you want the content itself to stretch across the page, you could do:
.header .center {
width: auto;
}
And that style would override the .center style, and make the header's content extend to the edges of the page.
Good luck!
The more semantically correct way of doing this is to put your header outside of your main container, avoiding the position:absolute.
Example:
<html>
<head>
<title>A title</title>
<style type="text/css">
.main-content {
width: 70%;
margin: 0 auto;
}
</style>
</head>
<body>
<header><!-- Some header stuff --></header>
<section class="main-content"><!-- Content you already have that takes up 70% --></section>
<body>
</html>
The other method (keeping it in <section class="main-content">) is as you said, incorrect, as a div (or section) is supposed to contain elements, not have them extend out of bounds of their parent div/section. You'll also face problems in IE (I believe anything 7 or below, this might just be IE6 or less though) if your child div extends outside the parent div.
Trying to put a div id inside another div id, but having problems. The html is simple enough, a div inside a div with two closing divs beside each other, but I can't for the life of me get the css correct. I feel really silly asking such a newbie question, please help. I want the css to display the html with the outer container with a background color that shows around the outside of the inner container.
Can you give me an example of the css required for this? Thanks for your help, -Matthew
Here you have example on JSFiddle:
http://jsfiddle.net/JXUeF/1/
if your html looks like this (this is how i understood your description):
<div id="outer">
<div id="inner">
some content here
</div>
</div>
your css should look like this:
#outer{
background-color: red;
padding: 5px;
}
#inner{
background-color: blue;
}
Ok here is the site:

If you view the source for the HTML and CSS you can see that I have set the height of the div in the middle to 100% and given it an overflow property value of hidden, it is called "main_content". I realized that the height value is having no effect on what is displayed, the overflow value of hidden is allowing the background color of the main_content div to extend down to the footer. I guess I am wondering what the best way for me to achieve a variable div height on each page or "main_content" while maintaining the background color. Am I doing this the right way or am I using some kind of css hack that is not the proper way to do it. All insight is welcome. Make sure to take a look at the source HTML and CSS before giving me an answer.
The easiest solution would be to assign the background color to your body element. Something like this:
body {
margin: 0;
padding: 0;
width:100%;
height:100%;
background-color:#cccccc;
}
This will also eliminate the few pixel white border around the edges, if you want to maintain that, take out the margin and padding declarations.
I might have misunderstood what you want, but try this:
Replace div#intro_container with:
div#intro_container {
width:830px;
margin:auto;
overflow: hidden;
background-color:#333333;
}
And remove the height property from div#messagebox.
I prefer to do in this way:
In the content of div 'main-content', add
In your case it was
<div id="main_content">
<div id="navigation">..</div>
<div id="intro_container">..</div>
</div>
It cam be rewritten as
<div id="main_content">
<div id="navigation">..</div>
<div id="intro_container">..</div>
<div style="clear:both"></div>
</div>
AFAIK This is a standard way to achieve what are you doing.
I've used the last example on this page for equal height columns.
http://www.ejeliot.com/blog/61
The problem is, when you click an internal anchor link, the content is shifted up, and the overflow is making the top part of the page disappear.
For example, click this link
http://www.noosanativeplants.com.au/~new/articles/botany-words/
Then click a letter to jump to that section. You will notice what I am describing.
Is there a way to combat this, or is this a short coming of the technique? Do you recommend I use the background image technique for faux equal height columns? I'd rather not use this, as one page has a different background, and would require a bit of reworking to do the background for this page.
Thanks
I really recommend you to use the fail-safe faux columns method. If you are not a layout expert (no offence, seriously), stay away from the padding/margin/overflow magic and the one true layout technique. The latter is elegant but it can cause unwanted side-effects if you are to do heavy JS/DOM manipulations and all (see the problems listing).
As slink said you have two overflow: hidden rules in your css:
#main-container {
overflow:hidden;
}
And
#content {
overflow:hidden;
}
If you disable/remove these you will able to use your scrollbars again. Unfortunately the padding / negative margin "hack" will be visible. I recommend you to completely remove this solution and use faux columns. Faux columns background can be added to your #main-content or even the #content div (not just like the example in the ALA article that sets the background image to the body tag).
Good luck!
Update: Sorry, let me correct myself: to use faux columns in your case it is better to set the current background to the html element and the faux background to body element.
Assuming your equal height columns are the left menu and right content in that example, you could just use a margin-left property on the right-column and set the background colour of the container to the desired left-column colour. This would assume your right content always has a greater height than the left, but there are other ways round this.
#container {
width: 960px;
background-color: #000;
}
#menu {
float:left;
width: 240px;
}
#content {
float:right:
margin-left: 240px;
background-color: #fff;
}
<div id="container">
<div id="menu">
<ul>
<li>Home</li>
</ul>
</div>
<div id="content">
stuff goes here
</div>
</div>
The problem is caused by two overflow: hidden; rules defined on elements #content and #main-contaniner.
