ユーザーがバナーをスクロール'.full-width'したときに追加および削除する単純なクラスがあります。目標は、ユーザーがバナーの上または下にスクロールしたときに、<nav>を徐々に拡大または縮小することです。<nav>CSS の例からわかるように、nav にはtransitionプロパティ セットがあります。

なんらかの理由で、<nav>バーが拡張すると左側にスナップバックします。バーは右側でも正しく遷移し、バーの縮小は完全に機能します。

興味深いことに、これは Bootstrap 3 では正常に機能しているように見えますが、Bootstrap 4 の何かが原因でナビゲーション バーがスナップします。

私が見逃しているものを見た人はいますか？

var NAVBAR_HEIGHT_IN_PX = 50;

$(document).ready(function() {
  var bottomOfBannerContainer =
      $('.banner-container').offset().top +
      $('.banner-container').outerHeight(true) -
      NAVBAR_HEIGHT_IN_PX;

  $(window).scroll(function() {
    if ($(document).scrollTop() >= bottomOfBannerContainer) {
      $('#navbar').addClass('container');
      $('#navbar').removeClass('full-width');
    } else {
      $('#navbar').addClass('full-width');
      $('#navbar').removeClass('container');
    }
  });
});
#navbar {
  transition: all 0.8s ease;
}

.banner-container {

これは役立つかもしれません:に直接追加するのではなく、スクロール時にnavbar追加されたクラスでを囲むことができます。containernavbar

私は、スナップがプロパティの突然の追加または削除に何らかの形で関連していることを発見しましたmax-width. に追加max-widthするだけ.container-fliudで、次の jquery ですべてが美しく移行します。

let bottomOfBannerContainer =
  $('.banner-container').offset().top +
  $('.banner-container').outerHeight(true) -
  NAVBAR_HEIGHT_IN_PX;

$(window).scroll(function() {
  if (Ember.$(document).scrollTop() >= bottomOfBannerContainer) {
    $('#navbar').addClass('container');
    $('#navbar').removeClass('container-fluid');
  } else {
    $('#navbar').addClass('container-fluid');
    $('#navbar').removeClass('container');
  }
});

そして、次の単純な css の変更:

.container-fluid {
  max-width: 100%;
}
