positions elements relative to their normal position in the document flow.position: absolute
positions elements relative to the nearest positioned ancestor.position: fixed

Common Position Properties:
- position: Defines the type of positioning method (static, relative, absolute, fixed, sticky).
- top, right, bottom, left: Specifies the position of the element relative to its containing element or the viewport.
- z-index: Controls the stacking order of elements. Higher values are placed in front of lower values.
When using the position
property, make sure to consider the relationship of the element with its parent and sibling elements. Properly using position can create complex layouts, like fixed navigation bars or sticky headers.
