Absolutely position an element within another element with CSS. Posted May 30th, 2009 in HTML and CSS When an element is positioned absolutely with CSS it is by default relative to the window as a whole and not to the parent element. This post shows how to absolutely position an element within another element with CSS. The following screenshot shows what we are trying to achieve. The black boxes labelled "right div" in the screenshot below have the following CSS: As you can see the top right div is positioned 10px off the right side of the browser viewport and 10px below the top of the viewport. The second right div is absolutely positioned within the containing div. If the window is resized the top right div remains at right:10px and top:10px relative to the viewport but the bottom right div remains in exactly the same place, relative to the containing div. So how is this done? Position: relative; The full CSS for the above example is below: And the HTML: Absolute Positioning Inside Relative Positioning.
A page element with relative positioning gives you the control to absolutely position children elements inside of it. To some, this is obvious. To others, this may be one of those CSS "Ah-ha! " Moments. I remember it being a big deal for me when I first "got it". Here is a visual: The relative positioning on the parent is the big deal here. Might not look like a big deal in this small example, but it really is a significant change.

Understanding CSS Positioning part 1 Without a doubt, positioning, or the layout, is the hardest part of CSS. Not only because it ever so often varies between browsers, but also because CSS has a lot of ways to position an element, all with various (dis) advantages. This series of articles will thrive to explain the possibilities you have in positioning. It doesn’t only cover positioning, but also properties that define layout such as display and float, and a preview of the new CSS3 layout modules. This part will introduce the positioning and display property. Part two, which will be published next week, will go more in-depth with the display attribute and delve into the float property.
Display:hehwha? Before we start, it is worth noting that there are basically two types of ways to display an element in CSS: block and inline. Display:block; Block can be, quite literally, seen as a block. Display:inline; Display:inline is somewhat the opposite. Flow Positioning. Position:static; Position:fixed; North Pole: A Structural CSS Positioning Study. Set for printing In this tutorial, we will remove all the design elements from the recently released North Pole JumpStart and take a look at how it was constructed in a step-by-step process. The elements we will be concerned about in this walk-through are: The wrapper The banner The left column The main content area The footer The five elements listed above are the structural elements within the design and it is these elements we will be investigating as we work our way through this tutorial. Download the North Pole JumpStart . We'll begin at the body selector.
With these three values set to zero we have a "clean" starting point in that all the browsers that are likely to visit our site will have their default margin/padding/border values reset to zero.

Body { margin: 0; /* zeroes the margins on the body */ Learn CSS Positioning in Ten Steps: position static relative absolute float.
1. position:static The default positioning for all elements is position:static, which means the element is not positioned and occurs where it normally would in the document. Normally you wouldn't specify this unless you needed to override a positioning that had been previously set. 2. position:relative If you specify position:relative, then you can use top or bottom, and left or right to move the element relative to where it would normally occur in the document.
Let's move div-1 down 20 pixels, and to the left 40 pixels: Notice the space where div-1 normally would have been if we had not moved it: now it is an empty space. It appears that position:relative is not very useful, but it will perform an important task later in this tutorial. 3. position:absolute When you specify position:absolute, the element is removed from the document and placed exactly where you tell it to go. Let's move div-1a to the top right of the page: What I really want is to position div-1a relative to div-1. Footnotes 10.
