Jquery ui工作codepen但不是网站

Question

对不起，我知道我不应该在这里提出这类问题，但我真的无法理解。 .draggable函数正在使用this codepen。但是在我的网站上使用完全相同的代码和插件链接它不起作用？

我不知道该怎么办..非常感谢你能帮助我！

// Show hide on click

    function showNavi(){
        $("#navigationin").toggle(1000);
      $('#description.fa-chevron-down').toggleClass('rotate180');
      $('.rainbow').toggleClass('changecolor')
    };
// Scroll to top
	//Check to see if the window is top if not then display button
	$(window).scroll(function(){
		if ($(this).scrollTop() > 100) {
			$('.scrolltotop').fadeIn();
		} else {
			$('.scrolltotop').fadeOut();
		}
	});
	
	//Click event to scroll to top
	$('.scrolltotop').click(function(){
		$('html, body').animate({scrollTop : 0},800);
		return false;
	});

// Random color
function entryOver(classnm) {
    $(classnm).css('border-color',randomColor({
   luminosity: 'bright',
   format: 'hsl' 
}))
};
function notEntryOver(classnm) {
    $(classnm).css('border-color',"#dadada")
};

// Icons drop down
function iconsFunction() {
  $('#mainicons').toggle("bounce", { times: 3 }, "slow");
  $('#avatar i').toggleClass('rotateavatar');
};

  $( function() {
    $( ".about" ).draggable({cursor: "move"});
  } );
