This article describes how to use javascript to obtain the width of hidden elements and provides a good reference value. Let's take a look at the following lines in javascript:

(Function (doc, win, undefined) {var docEl = doc.doc umentElement, resizeEvt = 'orientationchang' in win? 'Orientationchang': 'resize', recalc = function () {var clientWidth = docEl. clientWidth; if (clientWidth === undefined) return; docEl. style. fontSize = 20 * (clientWidth/320) + 'px ';}; if (doc. addEventListener === undefined) return; win. addEventListener (resizeEvt, recalc, false); doc. addEventListener ('domainloaded', recalc, false)}) (document, window );

The above is all the content of this article. I hope this article will help you in your study or work, and I also hope to support PHP!
