I have a content div where all the content is located. this div has a border. I would like to place things inside this div so that this div expands if the content inside is too big. Should the items inside the content div be a "div" or a "p" and what css position should they have?
CSS:
#content{
position: relative;
margin-left: auto;
margin-right: auto;
border: 1px solid #E0E0E0;
min-height: 200px;
width: 1000px;
padding: 0px 0px 80px 0px;
background-color: #fff;
}
When you set width: 1000px; it will prevent the content div from being any wider. I suspect you want min-width: 1000px; instead.
For internal content use p tags if you are creating paragraphs that only use inline html elements. If you are using block level elements then use div tags.
I can't say how you should style your internal elements because I know nothing about your design specs.
Contents of the #content div can be either p or div elements its up to you. The #content div will expand to the height of its content either way unless you have elements inside #content with a float property.
If that is that case you can do something like below to make the #content div expand its height.
<div id="content">
<div style="float:right; border:1px solid red; height:500px;"></div>
<div style="clear:both;"></div>
</div>
The important part here is the latest div with clear:both property which fixes the height of the parent element.
You should still be able to use a DIV. If you use height:auto; that should make it expand based on your content. Also I think you can use min-height:200px; and height:auto; together; With that said. I also agree with mrtsherman, if you set a width or height to a specific pixel it is going to limit you to those constraints.

Using a CMS, users of my site create posts containing images of various sizes. I'd like to wrap a container div around each image, but only with say 10px of padding on the left and right. That is, collapse the outer div's width to the width of the image + 20px. Is there an easy way to do this using css?
try this:
DEMO
HTML
<div class="image-wrapper">
<img src="http://placehold.it/500/500" />
</div>
CSS
img{
max-width: 100%;
}
.image-wrapper{
padding: 10px;
background-color: gray;
float:left; /* or instead display:inline-block; */
}
I have a parent div and child div. The child div width set to 100%.
Both have borders on them of 2px.
What is strange is the left edge of the child div shows up while the right edge seems to be covered up by the parent div.
Changing margin on child div or padding on parent div doesn't seem to do the trick.
Resizing child width to something lower than 100% seems to work but don't want to do that and not sure why it is happening?
FIDDLE: http://jsfiddle.net/Boovius/8armB/2/
HTML
<body>
<div id='parent'>
<div class='child'></div>
</div>
</body>
CSS
#parent {
height: 550px;
width: 400px;
margin: 0 auto;
border: 2px solid
overflow: scroll;
}
.child {
width: 100%;
height: 50px;
border: 2px solid
}
Border is included in width calculations by default. Change (or simply remove) your width or your box-sizing mode:
http://jsfiddle.net/isherwood/8armB/3/
.child {
box-sizing: border-box;
}
http://css-tricks.com/box-sizing/
If you don't change the display-property, divs are rendered as block elements and therefore always fill the whole width of their parent elements. Depends on how realistic you example is, but in that case just remove the width on the child div.

I was under the impression that when using % or auto for margins on a div contained within another div the position would be calculated in respect to the parent div.
So if I have a div with height: 50%, margin-top: 25% and margin-bottom: 25% the box should centre vertically within the parent div.
When I do this though the div centres on the page not the parent div.
The CSS
div#header {
width: 100%;
height: 100px;
margin: 0px;
position: fixed;
}
div#leftnavigation {
height: 50%;
margin-top: 25%;
margin-bottom: 25%;
float: left;
}
And the HTML
<!--Title and navigation bar-->
<div id='header'>
<!--Left navigation container-->
<div id='leftnavigation'>
<p>efwfwgwegwegweg</p>
</div>
</div>
In my case there are other divs floated to the right of the one detailed above, but any one of them behaves the same way. I'm assuming I'm doing something daft but I've been over all the other questions I could find along these lines and still can't figure it out.
EDIT
Here's the JSFiddle as requested http://jsfiddle.net/ChtVv/
UPDATE
I've tried removing the margin constraints and setting the leftnavigation div to height: 100%, this works so the issue is with the margin attribute?
The reason it didn't work is that percentage-margins are percentages of the parent's width, not its height. You can tell this by using margin-top: 25px; margin-bottom: 25px;, and also by increasing the width of the right-panel in jsFiddle.
In all cases % (percentage) is a valid value, but needs to be used
with care; such values are calculated as a proportion of the parent
element’s width, and careless provision of values might have
unintended consequences.

CSS is tricky!! :D
This is a borrowed technique to centre vertically and horizontally, but it would involve changing your HTML and CSS. I am not sure how flexible you are with your code:
CSS:
#outer {width: 100%; border: 3px solid red;}
#middle {width: 100%; text-align: center;border: 3px solid green;}
#inner {width: 200px; margin-left: auto; margin-right: auto; text-align: left;border: 3px solid blue;}
/* Courtesy: http://www.jakpsatweb.cz/css/css-vertical-center-solution.html */
HTML
<!--Title and navigation bar-->
<div id='outer'>
<!--Left navigation container-->
<div id='middle'>
<p id="inner">efwfwgwegwegweg</p>
</div>
</div>
You can build upon this to achieve whatever you are after!

Ok, so there are a lot of reasons why this would not work.
The main reason would be that your container has position:fixed;
When adding position:fixed; to a element, it no longer reserved it's space in the DOM and won't contain it's children.
I have made a example of the best way (in my Opinion) to center your child both Vertically & Horizontally
Here is a demo.
Demo
And here is the code.
<div id="container">
<div id="child"></div>
</div>
#container{
width:100%;
height:500px;
background:#CCC;
margin:0;
}
#child{
width:50%;
height:50%;
background:#EEE;
position:relative;
top:25%;
left:25%;
}
With CSS alone, is it possible to obtain the following example, http://jsfiddle.net/LdJ7t/, without explicity knowing the child element's width before hand?
The final result desired:
parent element scrollable to child element
child element's width set to content
#Parent {
width: 100px;
height:200px;
background: #ccc;
overflow:auto;
padding: .5em;
margin: .5em;
}
#Child {
width:300px;
height:100px;
background:yellow;
}
<div id="Parent">
<div id="Child">
This is a test. This is a test.
</div>
</div>
It looks like display:inline-block; almost works: http://jsfiddle.net/LdJ7t/1/
I think this is possible. I just can't find a solution.
Your inline-block solution is correct - if you put longer words in or an image, the scrollbar will appear. Text is broken on white space by default.
If you don't want text breaking on white space, you can add white-space: nowrap; to the child div like here: http://jsfiddle.net/LdJ7t/2/
I have JS generated content and want a div EXACTLY around it.
I don't know why, but the div parent is always 100% wide.
I thought I have div width: 100% somewhere, but surprisingly it looks almost the same in jsfiddle:
http://jsfiddle.net/f2BXx/2/
So why the outer div is always 100% wide? And how to fix that? I was trying with display: inline, but it sets width to 0px ;/
CSS:
.outer {
border: solid 1px red;
}
.item {
height: 300px;
width: 400px;
border: solid 1px blue;
}
.allright {
height: 300px;
width: 400px;
border: solid 1px blue;
outline: solid 1px red;
}
HTML:
<p>I don't know where "outer" div 100% width comes from?</p>
<div class="outer">
<div class="item">
<p>Something big!</p>
</div>
</div>
I always thought it'd look like that:
<div class="allright"></div>
I can't set outer div width (width: xxxpx) because all the content is dynamically created.
It sounds like you need to read the Visual Formatting Model.
display: block; causes block-level items to automatically fill their parent container.
CSS is designed in a way that lends itself to the child elements filling their parents, rather than the parents conforming to the children.
div is block element.
Block elements are 100% width of parent element, if width is not specified.
it's taking up all the available space based on it's parent container, exactly what it's supposed to do. If you want it to be a specific width set the width:; of the element.
If you find the w3.org documentation a little bit dry or too technical, here is a more accessible explanation of the CSS box model: https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Box_Model/Introduction_to_the_CSS_box_model
