文字在标题中而不是新的BS4中显示

Question

我的一页网站有问题。我的新文本部分在我的标题视频中显示。而是在我的新部分中。我想要一个视频标题。我在做什么错？

我的html

<header>
<div class="container">
  <div class="bg-wrap">
      <video poster="poster.png" autoplay="true" loop muted>
      <source src="img/video.mp4" type="video/mp4">
      <source src="img/video.webm" type="video/webm">
    </video>
    <div class="header-text">
      <h1>Elektro Sikora</h1>
      <p>Informační portál Elektro Sikora Český Těšín</p>
    </div>
    <div id="scroll">
      <div class="round">
        <div class="wheel"></div>
      </div>
      <div class="scrolling">
        <span class="arrow"></span>
      </div>
    </div>
  </div>
  </div>
</header>
  <section id="content-space">
    <div class="container">
      <div class="row">
        <div class="col-lg-12 text-center">

nav消失和可滚动视频

Answer 1

由于视频为 position: absolute;，因此不超出页面的流程。您需要向标头元素添加一个高度才能工作。

header {
    height: 100vh;
    overflow: hidden;
}

我希望这种修改后的CSS对您有用。

/* Nav */
.navbar {
  padding: 1.2rem;
}
/* Video */
.bg-wrap {
  position: absolute;
  z-index: -1000;
  width: 100%;
  height: 100%;
  overflow: hidden;
  top: 0;
  left: 0;
}
video {
  position: relative;
  top: 70px;
  left: 0;
  min-width: 100%;
  background: black;
}
.header-text {
  position: absolute;
  top: 0;
  width: 100%;
  min-height: 100%;
  z-index: 1000;
  background-color: rgba(0, 0, 0, 0.4);
}
