Reduce the built CSS size of an app using @allxsmith/bestax-bulma — measure raw and gzip size, then apply the cheapest lever that fits (lighter prebuilt CSS flavor, hand-rolled modular Sass build, import and icon-asset hygiene). Use when the CSS bundle looks too big, a size budget or Lighthouse audit flags stylesheet weight, switching bestax.css to a versions/*.css flavor, or setting up a modular @use Bulma/Sass build.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Optimizing CSS size with @allxsmith/bestax-bulma

The JS side is tree-shakable (the **entire** library is ~65 KB min+gzip). The stylesheet is
not: a prebuilt flavor ships all of Bulma + the bestax extras regardless of which components
the app renders. Judge stylesheet weight by the **gzipped** transfer size — never the raw
`dist/` number.

## Always measure first

Run the production build, then measure the built CSS — raw and gzip:

```sh
npm run build
wc -c dist/assets/*.css            # raw bytes (what Vite reports)
gzip -c dist/assets/*.css | wc -c  # transfer bytes (what users download)
```

Re-measure after **every** step below and report the before/after delta (raw + gzip). Never
claim a saving without a number.

⚠️ **~800 KB raw is ~82 KB over the wire.** Seeing ~800 KB of CSS in `dist/` is expected
with the default flavor, not a build misconfiguration — servers and CDNs gzip/brotli by
default. If the gzip number is already within the app's budget, say so and stop: "your CSS is
already fine" is a valid, honest outcome.

## Decision flow

Cheapest first. Use only the library's own shipped CSS builds and SCSS sources — do not add
…

How to install

The exact contents, by fingerprint

mdr add allxsmith/bestax/bestax-optimize@sha256:83f1ddcde2dba6b1

The line at the top of this page pins the label git:20261010.4d667b7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
