背景图片与另一个div

时间：2016-09-29 02:37:22

标签： javascript jquery html css

当视口变得更高或更宽时，我试图阻止重叠技能div的.background图像。我尝试过很多不同的事情，但我没有运气。请帮我！我对此非常陌生，所以如果我做了一些简单的愚蠢事情，请不要感到惊讶，因为这会造成这个问题。谢谢！

    $('.menu-icon').click(function(){
       $('.menu-nav').animate({

          }, 200
       );
  });

  $(window).scroll(function() {
    if ($(this).scrollTop() > 40 && flagScroll) {
        // apply effects and animations
