Good! I liked the space of the room and the service of the staff. I will definitely have a good experience slope 3 online.

You're welcome :D

Thanks @Dominik L. Now working perfectly

Use the component I linked

This one:
https://www.opensource-socialnetwork.org/component/view/5780/customs-css-js

Then go to your admin panel -> configure -> CustomCSS/JS and then under "frontend JS" you add this code

Thanks for the reply @Dominik L. Please can you tell me step by step on getting this done. Where should I add the code you gave? I’m not a pro with programming

Use Custom CSS/JS (click here) and add for frontend JS:

document.addEventListener('DOMContentLoaded', function () {
 var viewport = document.querySelector("meta[name=viewport]");
 if (viewport) {
 viewport.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no');
 } else {
 viewport = document.createElement('meta');
 viewport.name = 'viewport';
 viewport.content = 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no';
 document.head.appendChild(viewport);
 }
 });
