@unocss-applet/preset-rem-rpx

Coverts rem <=> rpx for utils.

Instal

npm i @unocss-applet/preset-rem-rpx --save-dev # with npm
yarn add @unocss-applet/preset-rem-rpx -D # with yarn
pnpm add @unocss-applet/preset-rem-rpx -D # with pnpm

Usage

import { defineConfig } from 'unocss'

import { presetRemRpx } from '@unocss-applet/preset-rem-rpx'

export default defineConfig({
  presets: [
    // ...
    presetRemRpx({ baseFontSize: 16, screenWidth: 375, mode: 'rem2rpx' }),
  ],
})

⚠️If you change baseFontSize other than 16 and use rpx2rem mode, you need to set the corresponding root font-size in H5.
