我试了很多次，但还是不行。向下滚动时，#custom-nav 背景变为黑色，不透明度降低。我不知道我错过了什么，或者有什么问题，有人可以帮助我吗？

样式.CSS

/*

#custom-nav {
	background-color:transparent;
	border: 0;
	box-shadow: none;

最佳答案 

<script type='text/javascript'>
jQuery(document).ready(function($) {
  $(window).scroll(function() {
    var scrollPos = $(window).scrollTop(),
        navbar = $('#custom-nav');

    if (scrollPos > 20) {
      navbar.addClass('bchange');
    } else {
      navbar.removeClass('bchange');
    }
  });
});
</script>

您的这部分代码会导致您的导航栏在滚动时改变颜色，如果您不希望这种效果只删除此代码。

它的作用是:检查当前滚动位置并为您的菜单添加一个类 .bchange #custom-nav
