Terminal Window Tabs in Tailwind CSS (Retro CRT)
A phosphor-green terminal: traffic-light title bar, tabs for three shells, scanlines, a vignette and a blinking block cursor after the prompt. The port sets the output in VT323, a face drawn from DEC terminal glyphs, and makes the glow a token-driven [text-shadow:…].

Which parts became utilities, which stayed CSS, and why.
- The scanline
repeating-linear-gradientported verbatim as an arbitrarybg-[…]; underscores carry the spaces. input:checked + .tt29bwith its text-shadow becamehas-checked:[text-shadow:…]— the glow colour is derived from the phosphor token withcolor-mix().- UI upgrade from the CSS original: output is set in VT323 at 20px with a CRT vignette and a blinking block cursor after the prompt; the window gains a soft phosphor halo.
- UI upgrade: resting tab labels raised from 50% green (≈3.9:1) to a solid 6.2:1 token; tabs are 40px tall with 44px rows on touch screens via full-width hit areas.

Demo: Terminal Window Tabs in Tailwind CSS (Retro CRT)
Source: https://codefronts.com/navigation/tailwind-css-tabs/terminal-window-tabs-tailwind-css-retro-crt/
A phosphor-green terminal: traffic-light title bar, tabs for three shells, scanlines, a vignette and a blinking block cursor after the prompt. The port sets the output in VT323, a face drawn from DEC terminal glyphs, and makes the glow a token-driven [text-shadow:…].

```How this works
Three layers make a CRT. Scanlines are a repeating gradient; the vignette is an inset shadow; the bloom is a text-shadow in the phosphor colour:
<div class="bg-[repeating-linear-gradient(0deg,transparent_0_2px,var(--color-ttb09-scan)_2px_3px)]
shadow-[inset_0_0_60px_rgb(0_0_0/0.6)]
[text-shadow:0_0_4px_color-mix(in_oklab,var(--color-ttb09-ph)_45%,transparent)]">The cursor only lives in the visible panel. Each panel ends with a block cursor; hidden panels are display:none, so only one blinks, and it stops under motion-reduce:.
Make it yours
- Amber terminal: phosphor
#ffb000; keep the scanline token at the same low alpha. - Denser grille:
transparent_0_1px,…_1px_2px. - Linux look: remove the traffic lights and left-align the title.
Gotchas — read before shipping
- Scanlines over a large area can repaint on scroll in older engines; keep the body modest in size.
- VT323 is a display face — keep it at 18px or larger for legibility.
- Text-shadow glow lowers apparent sharpness; resting tab labels use a solid token for contrast, not glow.
