Question

我在CSS中使用background-image属性设置了背景图像。通过大部分页面，它完美地运作。但是，当它到达某个<h2>元素时，背景图像不会显示在为<h2>定义的整个区域中。

我该如何解决这个问题？

＆＃13;

html {
  background-image: url("https://wallpaperscraft.com/image/city_hong_kong_night_clouds_lights_58330_3840x2160.jpg");
}

＆＃13;

<html>

<head>
  <meta charset="utf-8">
  <title>Dimstone</title>
  <meta name="description" content="Building the website">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js">
  </script>
  <link rel="stylesheet" href="main.css">
</head>

<body id="b-override">

  <h2 id="header">header</h2>

  <div id="top-navbar">
    <ul class="nav navbar-nav navbar-left">
      <li><a class="nav-link" href="#">HomePage</a></li>
      <li><a class="nav-link" href="#">SignUp</a></li>
      <li><a class="nav-link" href="#">About</a></li>
    </ul>
  </div>

</body>

</html>

Answer 1

不是h2，而是body标记（ID为#b-override）

添加此CSS：

body#b-override {
  background: transparent;
}

html {
  background-image: url("https://wallpaperscraft.com/image/city_hong_kong_night_clouds_lights_58330_3840x2160.jpg");
}

body#b-override {
  background: transparent;
}

<html>

<head>
  <meta charset="utf-8">
  <title>Dimstone</title>
  <meta name="description" content="Building the website">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js">
  </script>
  <link rel="stylesheet" href="main.css">
</head>

<body id="b-override">

  <h2 id="header">header</h2>

  <div id="top-navbar">
    <ul class="nav navbar-nav navbar-left">
      <li><a class="nav-link" href="#">HomePage</a></li>
      <li><a class="nav-link" href="#">SignUp</a></li>
      <li><a class="nav-link" href="#">About</a></li>
    </ul>
  </div>

</body>

</html>

CSS背景图像被h2元素取代
