YMMV: Your Mileage May Vary
Absolute positioning offsets are relative to the nearest "positioned" ancestor, or the viewport if there is no such ancestor. "Positioned elements" are elements with a value for the `position` property other than the default value of `static`.
What do you want to achieve with this? Why are you trying this solution? What's the original problem? Perhaps we can find another way to achieve what you want. See also: `xy
align bottom
Align an element to the bottom of its container: .container { position: relative; } .element { position: absolute; bottom: 0; /* older versions of IE may also need `left` or `right` set */ }

design resolution
Most users have 1024x768 and higher, but a large minority have 800x600. These numbers do not include those who browse using web appliances. It is important to note that (a) the display resolution says little about the size of the browser window, and (b) users can normally resize the browser window. Consequently no particular browser window size should be assumed.
