CSS Positioning strategies


    

  • inherit: use position value of container
    • 

  • static: normal layout (top left? default)
    • 

  • relative: offests from normal layout position
    • 

  • fixed: fixed position
    • 

  • absolute: offsets from the nearest container with a position attribute other than static
    •

  • more convenient to use css method rather than updating the style using attr
    •
