background-image我只是用black overlay代码写一个基本的。试试这个，希望能帮到你。谢谢

header {
  background-repeat: no-repeat;
  background-size: cover;
  color: #fff;
  display: flex;
  align-items: center;
  height: 100vh;
  position: relative;
  width: 100%;
}

header:before {
  background-image: linear-gradient(to bottom, rgba(0,0,0,0), rgba(0,0,0,0.35), rgba(0,0,0,0));
  content: '';
  position: absolute;
  left: 0;
  top: 0;
  opacity: 0.5;
  height: 100%;
  width: 100%;
}

.content {
  margin-left: 20px;
  position: relative;
}

<header style="background-image: url('https://images.unsplash.com/photo-1476820865390-c52aeebb9891?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&w=1000&q=80')">
  <div class="content">
    <h2>Title</h2>
    <p>Description...</p>
  </div>
</header>
