Visitors cannot zoom the page on their phone
Why it matters. Many people zoom web pages on their phone to read small text. A viewport tag with user-scalable=no or a low maximum-scale turns that off in Chrome on Android; only iOS Safari ignores it.
- Change the viewport meta tag to <meta name="viewport" content="width=device-width, initial-scale=1">.
- Remove user-scalable=no, and remove maximum-scale or set it to 5 or more; in WordPress this usually lives in the theme header or a mobile plugin.
