You can use CSS and the :empty pseudo-class to target elements with no content and set their background color. Here's an example:

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Set Background Color Based on Content</title>
  <style>
    /* Set default background color */
    .content-box {
      background-color: #e0e0e0;
      padding: 10px;
      margin: 10px;
    }

    /* Override background color when content is present */
    .content-box:empty {
      background-color: #ffcccc; /* Set your desired background color */
    }
  </style>
</head>
<body>
  <div class="content-box">
    <!-- This box has content, so it will have the default background color -->
    <p>This is some content.</p>
  </div>

  <div class="content-box">
    <!-- This box has no content, so it will have the overridden background color -->
  </div>
</body>
</html>

In this example, the .content-box class sets a default background color. The .content-box:empty selector then targets elements with the class that have no content and overrides the background color. You can adjust the colors and styles according to your preferences.
