Definition and Usage

The left property affects the horizontal position of a positioned element. This property has no effect on non-positioned elements.

  • If position: absolute; or position: fixed; - the left property sets the left edge of an element to a unit to the left of the left edge of its nearest positioned ancestor.
  • If position: relative; - the left property sets the left edge of an element to a unit to the left/right of its normal position.
  • If position: sticky; - the left property behaves like its position is relative when the element is inside the viewport, and like its position is fixed when it is outside.
  • If position: static; - the left property has no effect.
