HSL vs OKLCH comes down to one thing: HSL's lightness shifts across hues while OKLCH stays perceptually even. Here's why design systems switch in 2026.
A word-frequency workflow to spot repetition you can't see in your own drafts, tighten prose, and measure lexical diversity right in your browser.

OKLCH in CSS gives you perceptually uniform color, wider P3 gamut, and predictable lightness. Here is the syntax, the math, and the fallbacks for 2026.
RGB to HEX is base-10 to base-16 on three bytes. Here's the exact math, the JavaScript one-liners, alpha channels, and the mistakes that trip people up.
In JavaScript str.length counts UTF-16 code units, so one emoji reports 2 and a family emoji reports 11. Here is how to count emoji characters correctly.
Reading time and speaking time are not the same number. Here is how to estimate how long a talk runs from a script, using real 2026 words-per-minute rates.
A HEX to RGB conversion is just base-16 to base-10 on three bytes. Here is the exact math, the shorthand rule, alpha, and the CSS syntax for 2026.
A privacy-first diff checker runs in your browser so pasted code never leaves your machine. Here is why server-side diff tools are a real leak.
