  font-family: roboto, sans-serif !important;
}

.sans-serif {
  font-family: sans-serif !important;
}

import React from 'react';
import { TranslationProvider, useTranslate } from 'use-translation';

import TRANSLATION from 'translation/file';

import FONTS from 'translation/font';
import './path/to/font/css/file.scss/.less/.css';

export const MyApp = () => {
  return (
    <TranslationProvider fonts={FONTS} translation={TRANSLATION}>
      <App />
    </TranslationProvider>
  )
}

const App = () => {
  const { changeLanguage, translate, language } = useTranslate();

  const handleClick = () => {
    if(language === 'zh') {
