Html – How to redirect or disable mobile access to site?

I am building a very basic html-only site to display a specifically-sized project that is really only meant to be viewed on a computer. I seem to only find information on how to make your site mobile-friendly, but I want the opposite. Is there a way to redirect mobile users to a completley separate page, or to not allow the site to be viewed from mobile at all?

A lot of the answers that I have seen involve javascript or jquery but I would like to avoid that if possible

    <?php $iphone = strpos($_SERVER['HTTP_USER_AGENT'],"iPhone"); $android = strpos($_SERVER['HTTP_USER_AGENT'],"Android"); $palmpre = strpos($_SERVER['HTTP_USER_AGENT'],"webOS"); $berry = strpos($_SERVER['HTTP_USER_AGENT'],"BlackBerry"); $ipod = strpos($_SERVER['HTTP_USER_AGENT'],"iPod"); if ($iphone || $android || $palmpre || $ipod || $berry == true) { echo "](REDIRECT LINK HERE"; } ?>

    just redirects if you are in anything other than a phone.

    Without using javascript you can’t redirect to an other page when the user is in mobile. However you can change the display property in the body tag when a specific screen size is detected like this:

    /* Default styles for the body */
body {
  display: block; /* or any other default value */
}

/* Media query for screens with a maximum width of 600px */
@media screen and (max-width: 600px) {
  body {
    display: none; /* or any other value for mobile screens */
  }
}

    Or, if you need to redirect to another page, you have to use JavaScript:
    Use this code in your page to redirect to another url (or page) if a mobile browser detected:

    <script>
  window.mobileCheck = function () {
    let check = false;
    (function (a) {
      if (

  // The above function was imported from this answer: https://stackoverflow.com/a/11381730/19099302 by Michael Zaporozhets

  if (window.mobileCheck()) {
    window.location.href = "mobile.html"; // Replace this mobile.html with the page url you want to redirect
  }
</script>

    The window.mobileCheck() will check if the user is in a mobile browser. Then changing the windows.location.href will redirect to an other page. (Remember to replace that "mobile.html" to the url/page you want to redirect.)
