我使用 Skrollr 库为背景创建视差效果。但是，当调用 Skillor.init() 时，body 高度太高，并在页面下方创建了额外的空间。

    h3 { margin-top: 0; }

  }

JS：

$(function() {
  $('.dropdown-toggle').dropdown();

   $('.dropdown').hover(function() {
      $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeIn(200);
    }, function() {
      $(this).find('.dropdown-menu').stop(true, true).delay(200).fadeOut(200);
    });

  var s = skrollr.init({forceHeight: false});
});

我不确定哪个元素使页面太高。

skrollr.init({forceHeight: false});

Skrollr makes sure you can actually reach data-bottom-top. As you can see, the gap allows the element's bottom to be perfectly aligned with the top of the viewport.
