php - Can't get if-else statement to work while detecting screen resolution -


i'm making separate navigation bar on site handheld devices, i've come php script detects resolution , should output different navigation bars accordingly.

i'm not php yet, , took me while come rather simple script:

<?php if ($(window).width() < 764) : ?> <p>mobile navigation</p> <?php else : ?>  <p>normal navigation</p>     <?php endif; ?>

when use this, page not load within or beneath code, neither rest of page. i'd grateful if help.

thanks!

i think you're looking css media queries.

<style> #mobilenavigation {   display: none; } @media (max-width: 480px) {   #mobilenavigation {     display: block;   }   #desktopnavigation {     display: none;   } } </style>  <div id="mobilenavigation">mobile users see this</div> <div id="desktopnavigation">desktop users see this</div>

now, need little more thinking , designing, because you'll want entire site mobile friendly , responsive.
