Bootstrap 4 Исправлено перекрытие столбцов при уменьшении

На моем веб-сайте, построенном на Bootstrap 4 и PHP, у меня есть два столбца:

  • Левый столбец - который зафиксирован
  • Правый столбец - который должен прокручиваться

Столбцы правильно отображаются в браузере P C (как показано на рисунке 1), но при отображении на мобильном устройстве «Левый столбец» больше не должен быть исправлен.

При проверке отзывчивости «Левый столбец» все еще фиксируется и перекрывает «Правый столбец», показывая «Подача пользователя». (как показано на рисунке 2).

Я понимаю, что это потому, что <div class="position-fixed">, как я могу вызвать этот класс только для ПК / больших дисплеев?

Исправить на P C :

correct on PC

Перекрывающиеся столбцы:

overlapping columns

Мой код: 

<div class="container mt-3">
  <div class="row">

    // Left Column - fixed
    <div class="col-md-4">
      <div class="position-fixed">
        <h3>Left Column</h3>
      </div>
    </div> <!-- end column -->

    // Right Column - scrolling
    <div class="col-md-8 offset-md-4">
      <h3>User Feed</h3>
    </div> <!-- end column -->

  </div>
</div>

вам нужно переключить свойство position: fixed для размеров мобильных / настольных компьютеров ... вы можете использовать JS, чтобы сделать это, или написать класс для этого свойства самостоятельно ..., чтобы получить точный интервал / отступы и т.д. c. Вам понадобится css также

фрагмент ниже: 

.top-level-left {
  overflow: hidden;
  height: 100vh;
  position: fixed;
}

.top-level-left>div {
  padding-left: 0;
  padding-right: 45px;
}

@media screen and (max-width:576px) {
  .top-level-left {
    overflow: hidden;
    height: auto;
    position: relative;
  }
  .top-level-left>div {
    padding-left: 15px;
    padding-right: 15px;
  }
}

      <p>What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make
        a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages,
        and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.
        The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use
        Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
        Where does it come from? Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney
        College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32
        and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor
        sit amet..", comes from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced
        in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham. Where can I get some? There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form,
        by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators
        on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which
        looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.</p>
