Help:Wiki University Wikitext--Position - Absolute

Absolute positioning
Here is an object which we place 120 pixels from the top and 120 pixels from the left side of the page. 
 * It is like relative positioning, but it differs in fact that it does not create a space in the flow of the page.
 * Absolute position will cover up anything that is in that spot even another absolute positioned object.
 * NOTICE our object covers part of the sidebar.

Placing a absolute positioned object
Here is the coding for our absolute position object: 
 * NOTICE position:absolute.
 * NOTICE left:120px. If we would have use left:220px the sidebar would not be covered.
 * NOTICE top:400px.
 * So what happens if you don't specify the position in pixels? It places itself up against the object above it.

Absolute INSIDE relative positioning
  
 * One of the main problems with absolute positioning is that if you add new material the absolute positioned object will not move like relative positioning does.
 * In order for absolute positioned objects to move with the flow you have to place absolute positioned objects INSIDE relative positioned objects.
 * Relative positioned objects WILL MOVE even if there is an absolute position object inside of it.
 * Here is the coding for a relative placed object that has a red border with a absolute positioned blue box placed inside it.
 * Here's the coding:
 * NOTICE the absolute positioned blue box coding is between the opening and closing div tag in red.
 * You can have as many absolute positioned objects as you want between opening closing relative position objects.
