Skrollr 初始化设置 <body> 高度太高

Question

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

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。

Answer 1

skrollr.init({forceHeight: false});

Skrollr 确保您实际上可以联系到data-bottom-top。如您所见，间隙允许元素的底部与视口的顶部完美对齐。
