/* In CSS, px (pixels) is an absolute unit of measurement, representing a fixed size on the screen,
while rem (root em) is a relative unit based on the root font size of the document (usually 16px).

vh (Viewport Height) represents a percentage of the viewport's height,
which is the visible area of the browser window.
1vh is equal to 1% of the viewport height.
100vh equals the full height of the browser window.

% (Percent) is a relative unit that represents a percentage of the parent element's size,
but vh is relative to the viewport size.
