There are basically 2 methods to perform.
1.) CSS way
<style>
body {
background-color: lightblue;
}
@media screen and (max-width: 480px) {
body {
background-color: lightgreen;
}
}
</style>
2.) Javascript way
<script>
$(document).ready(function () {
/* detect window size to toggle menu */
if ($(window).width()<768)
{
isClosed = false;
$('.hamburger').toggleClass('is-open');
$('.hamburger').toggleClass('is-closed');
$('#wrapper').toggleClass('toggled');
}
});
</script>
This is just a snippet code for example.
