Explanation of Changes:
Added fixed top-0 left-0 w-full bg-white z-50 to the :class directive:
fixed: Makes the header fixed to the top of the viewport.
top-0 left-0: Positions the header at the top-left corner.
w-full: Makes the header take up the full width of the viewport.
bg-white: Sets the background color to white (or your desired background color).
z-50: Ensures the header is above other content.
With this change, the header will smoothly transition to a fixed position when the user scrolls down, preventing the jumping effect.
