I am trying to place a title and description in a out div that will wrap them. I have <div class="category_border"> wrapped around the title and description, but for some reason they are falling out of it. I have created a fiddle to help show what it is doing. Why aren't they falling in <div class="category_border">?

Add overflow: auto to the .category_border class.
Here's your updated demo:

The reason your title and description overflow the containing div is because both are styled with float: left. When you float an element it is taken out of the normal flow. Hence, as far as the container div is concerned they don't exist.
The answer is to "clear" the floats. There are many ways to do this. One way is to add overflow: auto to the container. This forces the container to expand to the height of the floated elements.

I'm having some problems with float issues and them floating outside their containers.
I know that you can use clears in this issue but I don't really understand what they do or where they should go to solve the problem.
I've created a clear class so I can use <br class="clear" />
Live site with the problem can be seen here:
http://www.rubytuesdaycreative.co.uk/testsite/shop.html
float means "Move to the side, and let content that follows this element appear beside it"
clear means "If something before me is floating, stay below it".
You can use clear to make a container expand around its floating content — by setting clear: both on a zero height element that appears after the floating content but inside the container — but it isn't the cleanest approach to solve that problem.
Set overflow: hidden on the container instead. This will establish a new block formatting context and cause the container to expand to contain the floated children.
Clear is used in the div that is being invade by the other. So if part of div1 goes into div2 and div one is left of div2, then in div2 insert clear:left.
To fix your problem add overflow:hidden to #content.
#content {
margin-top: 60px;
text-align: center;
overflow: hidden;
}
This is only one possible solution. Just as hint: http://www.quirksmode.org/css/clearing.html
To your question: I do not recommended you to add extra markup to your document to clear floats. It's a bad practice! A quite common and stable solution is the micro clearfix hack introduced by Nicolas Gallagher. You have only to add one class to your #content and you're ready to go.
You should apply clear: both to a block-level element (like div) after the last floated element. That way the cleared element will be positioned below all of the floated elements, and it will push the bottom of its container down to cover them.
Say you have a list of articles, some have a right floated image and very little text, so the image floats outside the article and into the next article, messing things up.
What is the correct/preferred/best way to make sure the elements inside the article does not float outside of it?
I know that overflow:hidden works, but is this correct usage? Or does it just happen to do what I want out of chance?
You have three ways to do it:
you can have overflow:hidden which is a clean way to do it.
Pros: It does not mess with semantics of the HTML, No "dead elements".
Cons: clipping the content if the container has a defined dimension, and clips shadows from inner elements.
div <-- style="overflow:hidden"
div <-- floating children
div
div <-- style="overflow:hidden"
div <-- floating children
div
You can have a blank element, usually a <div> after the container that has floats. Style this with clear:both.
Cons: Having a "dead element" in the DOM.
div
div <-- floating children
div
div <-- style="clear:both"
div
div <-- floating children
div
You can add a "clearfix" class to the container and use :after pseudo-class to add a "clearing dynamic dot/space". Basically it works like the second, but uses the :after to insert a space that has "clear:both" This article explains it.
Pros: It does not mess with semantics of the HTML, No "dead elements".
Cons: "classitis" (overuse of classes), :after is not supported in IE7 and older, thus CSS hacks are used
div <-- :after
div <-- floating children
div
" " <-- style="clear:both"
div <-- :after
div <-- floating children
div
You can use either of the three and they work great. I usually use 1 most of the time, and if I had shadows in the container, or if the container has a fixed dimension, I use 3. Method 3 relies on :after which is new. To support this clearfix, youd use an old CSS hack as described in the article.
For each article element, add clear: both;. This will ensure that images don't "leak" on the next article, but also makes sure they're not cut-off.
This link explains exactly what you asked.
overflow: hidden or overflow: auto would be acceptable solutions for clearing floats on smaller containing elements like a navigation bar that holds floated list items, or a call-to-action area that has a bunch of floated boxes.
And the link also explains the problem of using overflow:hidden to clear with a demo.
I'm trying to get the div wrapper to surround all the divs within it so depending on the amount of content the height of wrapper will grow.
I guessed that the way of doing this would be to set height: 100% but as you can see from the screen grab below, this is not the case.
Where it says 'No :-(' is what having height: 100% is doing where ideally I would like wrapper to be at the bottom where it says 'Yes' and I have drawn a red line.
Any help is much appreciated.
If you are using floats, giving the container overflow:hidden might fix the problem. If no fixed size is given to the div, this makes it stretch over the floated elements.
If you have absolutely positioned elements inside the container, it would be good to see the html/css for a solution.
Sounds like you need a clearfix.
http://css-tricks.com/snippets/css/clear-fix/
You'll want to define the clearfix class (as stated in the above link) add .clearfix to the #wrapper.
Can you post a link to the css?
The first thing that comes to my mind is the position attribute of the divs inside the wrapper. If they are set to float or absolute they will not be contained in the wrapper. That is intended behavior.
i.e. Here is a nice article about containing floats:
http://complexspiral.com/publications/containing-floats/
If, as is likely, that is the problem, you can either relative-position the inside divs or, if you are using floats, you can add an invisible block-displayed hr at the end of the wrapper, like so:
<div id="wrapper">
/*All divs to be contained here*/
<hr style="display:block;clear:left;visibility:hidden;">
</div>
The clear:left; is what gets rid of the "floating" of the previous elements. THe 'left' should be changed according to your floats.
More in the article above, this is the method i like best.
When I remove the display:block from a p inside a div, it ignores the top-margin or it's own hight or something like that. It snuggles up right next to the element above it. Does anyone know why?
The div is floated, the element above is not.
Inline elements simply don't take vertical margins or height into account. Block elements do.
Edit:
In response to comments, it looks like there are two issues at play here.
You have two elements with id='generals'. Change this to class='generals'.
Add overflow: hidden to your generals style. All of the elements inside it are floated, and so don't apply to the height of the element. Adding overflow: hidden changes how the element is displayed, clearing all the floats inside it.
I am using firebug to debug, one useful feature of firebug is when I click the element in HTML, firebug will show highlight on the actual browser window so that I know which part is currently selected.
But I noticed, with some css, below code is interesting:
<div>
<div>
</div>
</div>
The parent divs highlight area didn't cover the child div's highlight area. In my opinion, the child divs area should be a subset of parent's, is it right? In which cases that that is not true?
There are some cases:
If the child uses position: relative; top: 200px and move away from the parent.
If the child does something similar using a negative margin. (similar to 1)
If the child is a float, and there is no clearing or some kind of clearfix, such as the newest method of making the parent overflow: auto, then the parent will not enclose the floated child.
It is mostly likely because the child divs are floated. In this case you need to use a clearfix hack, or add an additional div into the container like so:
<div style="clear: both"></div>
It depends upon the style being applied. Generally what you are saying holds good. But positioning of a child element can be made independent of the parent.
You may please show the css to get clear idea.
If the inner element is floating or positioned absolutely, it won't affect the size of the parent.
If the inner element is floating you can change the overflow setting of the outer element to make it contain the child. You can specify overflow:hidden; for the parent element, but no size, which has the side effect that it will be sized to contain it's children.
