Posted 2021-05-03

// Smooth scrolling when clicking on a hash link
jQuery(function( $ ){
	$('a[href^="#"]').on('click',function (e) {
		e.preventDefault();

		var target = this.hash;
		var $target = $(target);

		//Adjust top position when header changes size
		if ( $(window).width() > 960) {
			var $scrollTop = $target.offset().top-72;
		} else {
			var $scrollTop = $target.offset().top-81;
		}

		$('html, body').stop().animate({
			'scrollTop': $scrollTop
		}, 500, 'swing');
	});
});
