解决方案


您可以使用非常简单的结构,如下所示:

HTML:

.wrapper {
  position: relative;
  width: 100%;
  background: url('https://images.unsplash.com/photo-1455582916367-25f75bfc6710?ixlib=rb-1.2.1&ixid=MXwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHw%3D&auto=format&fit=crop&w=1055&q=80') center center no-repeat;
  background-size: cover;
  height: 500px;
}

.overlay {
  position: absolute;
  bottom: 0;
  height: 100px;
  background-color: rgba(0, 0, 0, 0.6);
  width: 100%;
}

h3, p {
  color: white;
  margin: 0;
  margin-bottom: 10px;
  margin-left: 10px;
}
<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title>JS Bin</title>

<body>
  <div class="wrapper">
    <div class="overlay">
      <h3>This is the title</h3>
      <p>This is the main content</p>
    </div>
  </div>
</body>
</html>
