I was left speechless when I saw a CSS effect created by Román Cortés, which simulates the rotation of a Coca-Cola can on itself using CSS. It seems totally incredible to me that effects like this are possible despite the limitations of CSS, which make it clear that the only limitation is your imagination. To achieve this, it seems to leave a background with the entire side of the boat static (think of the rectangle that is left when disassembling a cylinder) using the “fixed” attribute of the “background-attachment” property and creating a kind of window that when scrolling creates the sensation of movement of the background. Spectacular.
