What are the properties of CSS "position" ?

static -    Elements renders in order, as they appear in the document flow. This is default.    
absolute - The element is positioned relative to its first positioned (not static) ancestor element    
fixed - The element is positioned relative to the browser window    
relative -    The element is positioned relative to its normal position, so "left:20" adds 20 pixels to the element's LEFT position
inherit  -    The value of the position property is inherited from the parent element
