Removing mobile nav when screen reaches certain width?

I want to remove my navigation menu when my screen reaches 750px +. Using jquery I thought this would work:

var $headerWidth = $("header").width();

if($headerWidth > 750) {
 $(".mobile-menu").css( "display", "none" );
}

however this isn't working. I think the code does work but I think I'm not calling it possibly what am I doing wrong guys?

maybe just use a css media query, something like this as a base and change to what you like:

@media screen and (max-width: 1050px) {
    body:after {
        content: 'tablet';
        display: none;
    }
}

On resize of the document window:

jQuery(window).resize(function() {
    var windowWidth;
    windowWidth = jQuery(window).width();
    if (windowWidth > 750) {
        jQuery(".mobile-menu").css( "display", "none" );
    } 
});
