CSS Position Sticky Vs Fixed

position: fixed sets the position of an element relative to the browser window, regardless of the scrolling position of the page. This means that the element will stay in the same place on the screen, even if the user scrolls down the page.

On the other hand, CSS position: sticky sets the position of an element relative to the user's scrolling position. This means that the element will behave like a position: relative element until it reaches a specified point (the "sticky point"), at which point it will stick to the top or bottom of the viewport.

On the other hand, position: sticky sets the position of an element relative to the user's scrolling position. This means that the element will behave like a position: relative element until it reaches a specified point (the "sticky point"), at which point it will stick to the top or bottom of the viewport.

Property	position: fixed	position: sticky
Positioning	Relative to the browser window	Relative to the user's scrolling position
Behavior on Scrolling	Remains in the same position on the screen	Scrolls with the page until it reaches a specified point, at which point it sticks to the top or bottom of the viewport
Sticky Point	Not applicable	A specified point at which the element becomes sticky
Browser Compatibility	Works on most modern browsers	Works on most modern browsers, but not supported on older versions of Internet Explorer and Edge

To sum up, position: fixed elements are always in the same position on the screen, while position: sticky elements are only sticky at a certain point & then behave like a relative element once they've passed that point.
