It's All-Relative A typical use of relative positioning is to push elements away from the expected position, without influencing other elements on the page. For example, if excess space exists between two headings, one way to remove the space requires one of the headings to be moved up or down, by overlapping the space of the other heading. Another primary use relative positioning exists for scripts, in order to animate text. However, scripts do not animate well, calling for a continual looping sequence. The usage of relative positioning calls for the usage of relative units.
Relative units compose themselves of percentages and ems.
Ems become highly used since it is exactly equal to the size of the font. Preference takes place with relative units since these units scale automatically. Depending on the look one wants to achieve for their page depends on the position used. Relative positioning remains easier to use since the placement of elements within absolute allows elements to be placed on top of each other and one does not have to figure out where the elements are hidden behind. Relative positioning also holds a better accuracy towards images and fonts with respect to sizing.
