then write in your gulpfile.js

const gulp = require('gulp');
const px2rem = require('gulp-pixel2rem');
gulp.task('default', function () {
  return gulp.src('./index.html')

    document.documentElement.style.fontSize = 100 * customWidth / 750 + 'px';
    addEventListener('load', function () {
      setTimeout(function () {
        document.documentElement.style.fontSize = 100 * customWidth / 750 + 'px';
        window.unit = 100 * customWidth / 750;
        var e = document.createEvent('Event');
        e.initEvent('adjustReady', true, true);
        window.dispatchEvent(e);
      }, 480);
    });
