大螢屏中的視頻-有解無憂

我一直在嘗試將視頻放入 Bootstrap 4 jumbotron，但遇到了一個奇怪的問題：我的內容掩蓋了視頻。顯然我不想那樣。jumbotron 和內容在移動設備上的差距在移動設備上也變得巨大。我也一直在嘗試解決這個問題，但沒有運氣。我也在這里嘗試了這個問題的其他答案，但它們也沒有奏效。到目前為止，這是我的代碼：

/* JUMBOTRON 
------------------------------------------------- */
.jumbotron {
  position: relative;
  z-index: -2;
  height: 62.5vh;
  padding: 0px !important;
  background-color: #FFFFFF;
}

.video-background {
  position: relative;
  overflow: hidden;
  z-index: -1;
  width: 100%;
  height: auto;
  background-color: transparent;
}





/* USP CONTENT
-------------------------------------------------- */


.marketing .col-lg-4 {
  margin-bottom: 1.5rem;
  text-align: center;

}
.marketing h2 {
  font-weight: 400;
}
.marketing .col-lg-4 p {
  margin-right: .75rem;
  margin-left: .75rem;
}


/* FEATURES AND QUOTES
------------------------- */

.featurette-divider {
  margin: 5rem 0; 
  width: 15%;
 
  height: 4px;
  border-top: 2px solid #FFD963;
}


.featurette-heading {
  font-weight: 300;
  line-height: 1;
  letter-spacing: -.05rem;
}


/* RESPONSIVE STUFF
-------------------------------------------------- */

@media (min-width: 40em) {
  /* Bump up size of carousel content */
  .carousel-caption p {
    margin-bottom: 1.25rem;
    font-size: 1.25rem;
    line-height: 1.4;
  }

  .featurette-heading {
    font-size: 50px;
  }
}

@media (min-width: 62em) {
  .featurette-heading {
    margin-top: 7rem;
  }
}

感謝您提供任何幫助！我知道我應該升級到 Bootstrap 5，但我還沒有時間學習它。

uj5u.com熱心網友回復：

您可以將您的內容嵌套background-video到一個部分并宣告該部分，height: 100vh;這將自動將您的其他內容推到下面。為了演示，我呼叫了 section section#video。我也將您main移到該部分下方。查看我在 CSS 和 HTML 中所做的更改。

.jumbotron {
  position: relative;
  z-index: -2;
  
  padding: 0px !important;

.video-background {
  position: relative;
  overflow: hidden;
  z-index: -1;
  width: 100%;
