Apply a retro CRT / scanline look to text, an image or a built-in demo scene. Tune every knob live, then copy the CSS or save a PNG. Your whole setup lives in the page address, so you can share it as a link.
Reduced-motion is on in your system, so animated effects (flicker, rolling band, live noise) are paused.
Paste this onto any element (give it class="crt"). Pure-CSS scanlines, aperture-grille, glow, chromatic-aberration, vignette and flicker all reproduce. True barrel warp can't be done in pure CSS — the snippet approximates the bulge with rounded corners; the PNG export captures the real warp.
