导航栏和第一部分之间的间距

Question

当我开始向下滚动时，家庭部分向下移动，中间是一个奇怪的空间，我不知道该如何摆脱。

有关如何解决此问题的任何提示？

//header Effekt beim scrollen

$(function() {
  var shrinkHeader = 100;
  $(window).scroll(function() {
    var scroll = getCurrentScroll();
    if (scroll >= shrinkHeader) {
      $('#navbar').addClass('shrink');
    } else {
      $('#navbar').removeClass('shrink');
    }
  });

  function getCurrentScroll() {
    return window.pageYOffset || document.documentElement.scrollTop;
  }
});
// JavaScript Document

$(document).ready(function() {

  var navTop = $('#navbar').offset().top;
  var navHeight = $('#navbar').height();
  var windowH = $(window).height();

  $('.section').height(windowH);

  $(document).scroll(function() {
    var st = $(this).scrollTop();

    //for the nav bar:
    if (st > navTop) {
      $('#navbar').addClass('fix');
      $('.section:eq(0)').css({
        'margin-top': navHeight
      }); //fix  scrolling issue due to the fix nav bar
    } else {
      $('#navbar').removeClass('fix');
      $('.section:eq(0)').css({
        'margin-top': '0'
      });
    }

    $('.section').each(function(index, element) {
      if (st + navHeight > $(this).offset().top && st + navHeight <= $(this).offset().top + $(this).height()) {
        $(this).addClass('active');

        var id = $(this).attr('id');
        $('a[href="#' + id + '"]').parent('li').addClass('active');
        // or $('#nav li:eq('+index+')').addClass('active');
      } else {
        $(this).removeClass('active');

        var id = $(this).attr('id');
        $('a[href="#' + id + '"]').parent('li').removeClass('active');
        //or $('#nav li:eq('+index+')').removeClass('active');
      }

    });

  });

Answer 1

当您向下滚动时，某种东西正在创建页边空白

尝试添加：

#Home {
   margin-top: 0 !important;
}

Answer 2

在查看您的代码时，我发现了几个问题。

if(st > navTop ){
    $('#navbar').addClass('fix');
    $('.section:eq(0)').css({'margin-top':navHeight});//fix  scrolling issue due to the fix nav bar
}

st被定义为浏览器的当前滚动位置。

这在您的滚动代码中，这意味着st大于navTop时，它将margin-top设置为navHeight。但问题是您按照如下方式定义了navTop：var navTop = $('#navbar').offset().top;

navTop始终为0。这意味着每当滚动任意数量时，它都会添加margin-top。我将从发现您的问题开始。

Andrea的解决方案只是您自己介绍的问题的解决方案。

Answer 3

尝试添加：

#Home {
       margin-top: 0 !important;
    }
