User Agent detection is not a recommended technique for modern web apps. You can use JavaScript window.matchMedia() method to detect a mobile device based on the CSS media query.

if (window.matchMedia("(max-width: 767px)").matches)
// The viewport is less than 768 pixels wide
document.write("This is a mobile device.");

Another approach would be a responsive media query. You could presume that a mobile phone has a screen size greater than x and less than y.

For example:

@media only screen and (min-width: 320px) and (max-width: 600px) {}

You may also use .

const isMobile =;
