将叠加图像保持在图像边界内 - 限制它仅粘附在图像上

Question

我正在尝试在图像上放置一个覆盖层，但是这个覆盖层延伸到了顶部的菜单栏上，我不知道如何只将其粘贴在图像上。

我尝试了不同的调整图像和更改位置的方法，但它仍然延伸到菜单栏上。当我调整顶部位置时，对于全屏来说是一个小修复，但一旦在移动设备上，由于菜单被隐藏，它将无法工作。而且，当尺寸改变时，它会在图像下方流动。

header {
  border-bottom: 5px solid coral;
  font-family: Arial;
}

header a {
  display: inline-block;
  text-decoration: none;
  color: inherit;
}

.bg-image {
  background-image: url('https://images.pexels.com/photos/1647120/pexels-photo-1647120.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=1');
  background-size: cover;
  background-position: center;
  background-color: blue;
  background-repeat: no-repeat;
}

.vh-80 {
  min-height: 80vh;
}

.banner-text {
  color: white;
  font-size: 3rem;
  text-align: center;
  font-family: Arial;
}

.bg-overlay>* {
  position: relative;
}

.bg-overlay::before {
  content: "";
  position: absolute;
  top: 0px;
  bottom: 0px;
  left: 0;
  right: 0;
  background: linear-gradient(0deg, rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0));
}

<header class="grid-spaceBetween-middle ">
  <div class="col-2 ">
    <a href="/index.html" class="logo">
      <p>Logo</p>
    </a>
  </div>
  <nav class="col-10">
    <a href="/#.html">About Us</a>
    <a href="/#.html"></a>
    <a href="/#.html">Business Travel</a>
    <a href="/#.html">Be Inspired</a>
    <a href="/#.html">Contact</a>
  </nav>
</header>

<!-- 图像横幅 -->

<section class="grid-spaceAround vh-80 bg-image bg-overlay">
  <div class="col-12-middle banner-text">
    <p>IT'S ALL <strong>GOOD</strong></p>
  </div>
</section>

我尝试过更改部分，尝试过相对位置的方法，但都没有成功。

在 .bg-image 上添加 position: relative，而不是在覆盖层 .bg-overlay > * 的每个元素上添加。

header {
  border-bottom: 5px solid coral;
  font-family: Arial;
}

header a {
  display: inline-block;
  text-decoration: none;
  color: inherit;
}

.bg-image {
  background-image: url('https://images.pexels.com/photos/1647120/pexels-photo-1647120.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=1');
  background-size: cover;
  background-position: center;
  background-color: blue;
  background-repeat: no-repeat;
  position: relative;
}

.vh-80 {
  min-height: 80vh;
}

.banner-text {
  color: white;
  font-size: 3rem;
  text-align: center;
  font-family: Arial;
}


.bg-overlay::before {
  content: "";
  position: absolute;
  top: 0px;
  bottom: 0px;
  left: 0;
  right: 0;
  background: linear-gradient(0deg, rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0));
}

<header class="grid-spaceBetween-middle ">
  <div class="col-2 ">
    <a href="/index.html" class="logo">
      <p>Logo</p>
    </a>
  </div>
  <nav class="col-10">
    <a href="/#.html">About Us</a>
