Detailed explanation of Vue px to rem configuration

// Base size const baseSize = 32
// Set rem function function setRem () {
  // The scaling ratio of the current page width relative to 750 width, which can be modified according to your needs.
  const scale = document.documentElement.clientWidth / 750
  // Set the font size of the root node of the page document.documentElement.style.fontSize = (baseSize * Math.min(scale, 2)) + 'px'
}
// Initialize setRem()
// Reset rem when changing window size
window.onresize = function () {
  setRem()
}
