Here is a very simply jsFiddle to demonstrate my problem: http://jsfiddle.net/ryandlf/mSmUv/4/
When an element has a top padding or margin and it sits on the first line within a div, the div does not respect that padding or margin and push the element down. In most cases this isn't an issue, but for example, if I have a button that has a top border and padding the top of the border will be cut off because the div is not taking into consideration the padding value.
Is there a workaround for this other than just blindly setting margins or padding on every container div element and hoping I have added enough to account for any internal element that might be affected?
your link with class button is not a block element, it is inline element. Change this default behaviour by adding dispaly: block to it and it will work as expected. Proof available on jsfiddle.
So to sum up, the problem is not with the div - it is the problem with css - inline elements ignore margin and padding because they cannot 'reserve space'.
UPDATE: To answer your comment, here is the solution you might be looking for
The button element is inline. To get the desired behavior you can set display:inline-block.
Check here
Try to add following to the parent div:
overflow: hidden
I hope it helps!

Here is a test-case for my problem:
http://game-point.net/misc/testParaPadding/
I want the progressBarGreen.png image to be inside the DIV, and the DIV is exactly the right height (15px) to hold it, but there are a couple of pixels padding at the top of the DIV. Why? The browser seems to be sizing the content as if it contained text because the padding changes if I remove the font-family styling for the body, but there is no text in the DIV.
Interestingly this problem doesn't happen in Firefox's quirks mode.
jsFiddle Example
You need line-height:15px on the div holding the image
edit: Explanation for this behaviour line-height affecting even no-text blocks
Your image is the right size, but images are inline elements by default, and will be affected by the page's line-height, font-size, and other properties of inline elements.
If you add a line to your image's style reading display: block;, it will become a block-level element, and not be affected by any of those properties.
The initial value for vertical-align is always "baseline".
You can fix that by adding a vertical-align:top to your image ;)
Use
position:absolute;
To get the image on the other DIV exactly inside it.

I was trying for display:inline property and I found same question for which I was looking....and here I got this answer, it makes me very clear ....but I am not clear about these lines ...
Basically margin, padding and border
can be set on inline-level elements,
but they may not behave as you expect.
The behavior will probably be OK if
there's only one line, but other lines
in the same flow will likely exhibit
behavior different from your
expectations (i.e. padding will not be
respected).
so please anybody can make me clear about these lines...I have also tried for display :inline here
You cannot set height, margin-top, margin-bottom, padding-top and padding-bottom on an inline element. You can set margin left and right an padding left an right.
You can set with on an inline element but then it will behave like a block element: See here
Inline Elements will always be displayed next to each other as long a they fit next to each other.
yes inline element behave differently other then block element. the main point of inline element is that is doesn't take vertical margin & padding.
inline elements like a, span
you can give inline-block instead of inline
this is a best example related to your question
http://www.maxdesign.com.au/articles/inline/
EDIT
yes, padding-bottom pushing the inline element down but it's not add any width to your inline element means when the content move to new line it's going to overlap each other & in block element margin, padding & border are adding width,height & space the block element

http://reference.sitepoint.com/css/inlineformatting
with this property set (display:inline) you can't set width and height of your element. Margin, padding & border is ok. I'd use floating instead, but that's because it gives me more flexibility sometimes. =]
It is saying that if you have an inline element that goes all the way to the right of the page and then wraps around to the left (for example, a single line of text that takes up two lines of space) then you may have unexpected consequences. In particular the padding may not display as desired.
An inline element, when it doesn't break on to multiple lines, respects left/right padding - so you see the padding-left and padding-right inside the left and right edges of the element respectively.
When the inline element does break on to multiple lines, the padding is somewhat respected, in that again both left and right inside edges of the element have padding. The part where it isn't respected is exactly the part where the element breaks, the break-point doesn't have any padding because it simply spreads itself onto the next line.
A block element on the other hand, does respect padding properly because it adds the padding and the contents of the element break inside that padding.
Here's a quick image to help explain what I've explained:
I have a div that is float: right and it is inside a parent div. There are p elements inside that same parent div also, and the text wraps around the float: right div properly.
However, if I set the p elements to have a border, or do a <hr />, the border does not stop where the text stops, but extends behind the float: right div.
Here is a beautiful mspaint depiction of the situation:
Note that the green part of the black horizontal line is behind the floating div.
How do I get the border or <hr /> or whatever to be only as wide as the text, and not go behind the div?
I know this problem was posted some time ago, but I had the same problem today and found another solution:
http://jsfiddle.net/MvX62/
I use border-bottom instead of the <hr /> tag and had to add an overflow: hidden;. Look at the fiddle, i think this is more useful then the accepted solution, because you can also add a margin to the horizontal line and there is the same gap, as the text has.
Also you don't need to define z values and don't need any hacks or workarounds.
I've had this problem before, and I wasn't sure if it was solvable.
In your case, however, you could wrap the green box with another element and swap margin with padding and set its background to #fff to cover the offending line.
Check out the fiddle...
http://jsfiddle.net/UnsungHero97/8BwGB/3/
What I did here was give the floated element a z-index CSS property, which will put it "above" the non floated element (which has a smaller valued z-index) and the <hr /> will not go above the floated element.
In regards to getting it as wide as the text, in my example it is as wide as the text, but I'm not sure if that holds across browsers (I'm on Chrome). Let me know if it doesn't.
I hope this helps.

p.s. excellent mspaint skillz :)
You would have to set the width of the paragraphs to the width of the container minus the width of the floating element, or you could give them a margin on the same side of the float equal to the float's width.
Div cannot wrap around another div. Wrapping is text-only property. You can simulate wrapping by setting the margin-right for the master div to the width of the div you want it to wrap, but text wil not flow under the inset div.
Some values of the overflow property can cause this behavior. Specifically, overflow: visible which is often set by popular CSS resets/normalization.
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 have an element in a div, which has a background image. Below the div I have another div with another background image. Now the problem is that if the last element contained in the first div has margin-bottom applied there will be a gap between the 2 divs like this:
Screenshot http://img40.imageshack.us/img40/5603/littlesnapperh.png
Notice the gray gap caused by the margin-bottom property of the h2 element contained within the first div. I know this can be solved if I switch margin-bottom to padding-bottom but what if I need margin-bottom?
How to fix this?
This is a feature known as collapsing margins. See: http://www.w3.org/TR/CSS2/box.html#collapsing-margins
The easiest way around (aside of replacing the margin with padding as you suggest) is to add a small (1px) invisible border or padding to the outer element.
Probably something to do with overflow:hidden or one of the elements not clearing properly. If add overflow:hidden to the first div it might fix it.
