A retro television illustration created entirely with a single HTML div and complex CSS gradients.

Single Div Vintage TV CSS Illustration

Single Div Vintage TV CSS Illustration is a masterclass in CSS gradient art. Using only one div and its ::before/::after pseudo-elements, it renders a retro television set. The body, screen, antenna, and speaker grill are meticulously drawn using layered linear-gradient, radial-gradient, and repeating-linear-gradient. The mask-image property is cleverly used to carve out the control knobs. A brilliant example of pushing CSS drawing to its limits.
