Differences between CSS position and four attributes [Collection]

Absolute 
 Generates absolute positioning elements, which are located relative to the first parent element other than static positioning. 
 The positions of elements are specified by the "Left", "TOP", "right", and "bottom" attributes. 

 Fixed 
 Generates absolute positioning elements, which are located relative to the browser window. 
 The positions of elements are specified by the "Left", "TOP", "right", and "bottom" attributes. 

 Relative 
 Generates relative positioning elements and locates them relative to their normal locations. 
 Therefore, "Left: 20" adds 20 pixels to the left position of the element. 

 Static 
 Default value. The element is not located and appears in the normal stream (ignore the top, bottom, left, right, or Z-index declarations ). 

 Inherit 
 Specifies that the value of the position attribute should be inherited from the parent element. 

 Generally, absolute positioning of absolute is used.
