function refreshRem() {
var width = docEl.getBoundingClientRect().width;
if (width / dpr > 540) {
width = 540 * dpr;
}
var rem = width / 10;
docEl.style.fontSize = rem + "px";
flexible.rem = win.rem = rem;
}when looking at the source code of flexible, there is such a paragraph. I would like to ask why width is set to 540 * dpr when width / dpr > 540s.
because Taobao sets a limit for the screen width of a mobile phone. The maximum screen width is 540. If you exceed 540, you are not considered to be a mobile phone.
