SvelteKit, Qwik, and Solid.
Inspect any traceless-style class on the live page in real time:
- Inspector — pick any element and see every
tl*class on it, the (property, value, selector) triplet each class
encodes, the cascade order showing which classes are currently contributing styles vs. overridden, and inline
conflict warnings when two classes set the same property. - Classes — searchable browser of every
tl*class on the page with use-counts. Filter byprop:valuesyntax. - Tokens — every
--tl-*CSS custom property surfaced from yourtl.defineTokenscalls, light and dark variants
side-by-side, live-editable. - Theme — toggle dark mode and RTL direction live, preview different
tlTheme*overrides without touching code. - Animations — list every
@keyframesregistered viatl.keyframes, with a one-click preview button per
animation. - Stats — rule count, used-class count, CSS bundle size, token / theme / animation counts.
