The form at the top of this page: http://kgshowroom.com/test/builder-test.html is supposed to go under title "Testing the Builder Thing" but no matter where I put the "header" "div" or "article" tags around the iframe for the form, it doesn't budge. I tried looking into the css for it, but I must be missing something. And I know it's gotta be a simple something!
Any ideas?
You have the CSS value position: absolute; set on the form's parent iframe. That removes it from the normal document flow, which prevents it from affecting the positions of any sibling elements (i.e. it overlaps them instead of pushing them out of the way). It also makes the browser calculate the iframe's position relative to its containing block rather than its sibling elements (though only if used in conjunction with the top, right, bottom, or left properties). That, together with the CSS value, top: 0;, is why the iframe is stuck at the top of the page.
Changing the position value to relative will fix the problem. Deleting the top, right, bottom, and left properties might also work, but I'd try the relative positioning first. Look here for more info on CSS positioning.
Moving the <div id="FormLoginPage"> after the iframe seems to do the job with me in the DOM.
I've got a problem with putting a div below an absolute positioned element which doesn't have a fixed height. The codes are too long to paste here, so I'm posting the link to the html file instead; http://infomailer.kotra.or.kr/20141127/oisy.html
I need to move that 'dd' to the bottom of the document, not using margin or absolute-positioning because this document is to be read by mobile devices as well. What should I do to keep the main structure of tab module and fix the problem?
I am unsure how to position elements using css, as when I use methods like the following, whenever I resize the browser, the elements stay in the same place instead of where I would like them to be on the resized document. Please can you tell me what I am doing wrong?!
.logo {
left: 20px;
top: 20px;
position: absolute;
}
#header h1 {
margin-top: 20px;
margin-left: 500px;
color: rgb(127, 127, 126);
line-height: 0px;
}
Please, have a fiddle - http://jsfiddle.net/hHGRc/
Within the (X)HTML DOM, CSS recognizes four types of positioning. By default, every element in HTML is positioned Statically. This means that it is positioned according to the place that it appears in the normal flow.
Relative Positioning
When an object is positioned relative, it means that it modifies the position based on the origin, which is where it would have been positioned in the normal flow (static). Relative also does something else special, however, and tells the browser that all of its children will be positioned according to this element, whether using relative or absolute.
Absolute Positioning
When an object is positioned absolute, it is placed according to the position of its nearest non-static positioned ancestor. If there is not one, then it uses the <body> to determine its position. This has the potential to break document flow, if its siblings or ancestors are not positioned absolute. If all are positioned absolute from the outer most top node to current node, then it will maintain the flow.
Fixed Positioning
This takes the element out of the flow and positions the object according to the Window object. This means that no matter the scroll state of the document, its size or any other property, it will always appear in that location. (This is how you get objects that scroll with you).
Multiple solutions to your issue
First, as described by others, you may add position:relative to the #header. It will, like explained above, make your header the nearest non-static ancestor and will use it and the basis for determining position. This is probably not ideal for you because you are an admitted novice and this one absolute could easily break enough flow that you may struggle with sibling elements.
As an alternative, you may change the logo from position:absolute to position:relative. This will keep your logo in the flow, but move the logo according to where it appears naturally in your document flow. Chances are that unless you are using floats in your #header, this is probably the one you want, as it a) keeps flow, b) allows for use of child element floats without losing flow, c) achieves your ideal positioning, d) keeps inheritance from parent elements (when it is important).
Another choice is to change the #header to position:absolute. This may alter the way everything interacts, however, unless you change all of your parent and sibling elements to position:absolute. Additionally, you may lose access to ancestor defined widths and heights, as they are only inherited if they are in the same flow. This is the 2nd best situation for you as you can simply add the rule body * { position:absolute; } and all will remain in the flow with you. However, it neglects to really teach you the things you need to learn about positioning and will simply be a crutch.
Hope this helps,

Defining position: absolute in CSS takes the element in question out of the flow of the document.
Think of this as layers: the bottom most layer is the document (though not always, depending on z-index!), and the top most layer is your element which you have defined as absolutely positioned.
By setting position: absolute, you have told the browser that you will be responsible for positioning the element relative to the top left corner of the document (screen). Above, you have told the browser to position #logo 20px from the left and 20px from the top of the document. When you resize your browser viewport, that element will remain in that position.
I think what you want is to position your element within the document flow, without using absolute positioning. This can be achieved with a combination of floats, margins, and padding.
CSS positioning can be tricky to understand correctly, but once you do, you'll find it very useful.
Try this: http://www.barelyfitz.com/screencast/html-training/css/positioning/
Basically, to position anything that needs to be locked to a parent or a container element, the parent or container element itself needs to be positioned as well (absolute, or relative, doesn't matter) this is called positioning context. If an absolutely positioned element cannot find a parent or container that is positioning itself, it will then use the `body as the positioning context.
So in your example, if i were to to guess without seeing your HTML and more of your CSS,
adding position:relative to #header would then allow .logo to position itself absolutely from the top left of the #header element.
Also important to remember that absolute positioning takes the element out of the normal flow of the document.
I'm going with a wild guess and saying that your logo is inside the header division, but your header is positioned staticly. Therefore, your logo is not being positioned according to the header, but according to the document's window. So it will be going to a position that is 20px right and 20px down from the top left corner of the document in all instances.
Try setting position: relative on your #header element. This will keep the header in the same place as it would always appear, and the logo will use the header box to find it's left and top positions rather than the browser window.
Basically, I have a form, outside of that form in this random space on my page I want to position a div (containing two buttons). I've looked at using absolute positioning. However, it is positioning it outside of the page wrapper.
How can I get the positioning to be specified from the corner point of the actual page and not the window?

You need to add position: relative to the element you would like the top and left values to be offset from.
That might be your form, or it might be your #container/#wrapper element.

Looks like you have your answer by now. But ill post this anyways.
A simple and short example which shows how relative positioning to parent is done.
http://jsfiddle.net/EadXw/
If you want it positioned top:0;left:0 on the page, place it immediately after the <body> tag.
If it is wrapped in anything the containers may change it's position. Make sure it is independant and not influenced by any containers.
Sounds like you should read up a bit on the flow of the DOM.
Positioning with CSS and HTML
Make sure your <form> element wraps your whole "page" and that the <div> with the buttons is the first child of <form>.
When you do this you can add the rule position:relative to the form and position:absolute to the <div> and move it around with top and left.
Another option is to have no position rule on the form and have position:relative on the <div>. This is more compatible with iPad and iPhone devices, which don't like absolute positioning. When you go for this approach be sure to have a fixed height for the <div> and a negative margin-bottom of the same size.
On this website: http://fa-aft6157.org/ , when viewed in IE8, when you hover the mouse over the links on the left they appear at the top of the page. How can this be fixed in the HTML code?
Whenever you position an element absolutely with css, the element is positioned relative to the closest parent that has position defined.
I think your problem has to do with the fact that all of your menu DIVs are direct children of BODY. You may have better luck placing your menu DIVs inside a parent DIV that has position defined.
