The word "cyberpunk" comes from Bruce Bethke's 1983 short story, but the visual identity was forged by Ridley Scott's Blade Runner (1982) and William Gibson's Neuromancer (1984). Rain-slicked streets, kanji neon, layered urban density, CRT green — these became the genre's vocabulary.
On the web, cyberpunk aesthetics first appeared in the late-90s Flash scene and early-2000s forum skins. The release of CD Projekt Red's Cyberpunk 2077 in 2020 reignited mainstream interest, and designers began translating the visual language into modern CSS — clip-path for angular panels, layered box-shadows for neon glow, and repeating-linear-gradient for scanlines.
Today it lives in gaming sites, demo pages, and creative portfolios that want to feel dangerous. Its closest relatives are synthwave (which shares the neon but swaps dystopia for nostalgia) and retro-terminal (which strips out the color and goes full monochrome).
