Preflight styles

Preflight is a set of base styles that are applied to your app by default. These styles are designed to make your app look consistent across different browsers and devices.

Preflight can be disabled by setting preflight to false in your jux.config file.

jux.config.ts

export default defineConfig({
  preflight: false,
});

Here’s all the styles that are applied by preflight:
