Question

如果我的问题很愚蠢，请原谅我，我对所有这些技术都很陌生。我的目标是在它没有缩放的情况下添加默认大小的图像背景，因为它是一个大尺寸的图片，问题是当我添加一些样式时，图像没有显示，背景变得空白。顺便说一句，IM在这个背景图像的顶部使用particle.js。

 #particles-js{

  background: url("https://d14xs1qewsqjcd.cloudfront.net/assets/bg-header-star.jpg")
  width: 100%;
  min-height: 800px;
  background-size: contain;
  background-repeat: no-repeat;
  background-position: center;
  /* background-attachment: fixed;
}

Answer 1

你没有在background属性后添加分号：

#particles-js{

  background: url("https://d14xs1qewsqjcd.cloudfront.net/assets/bg-header-star.jpg") /* <---- Semicolon goes here*/
  width: 100%;
  min-height: 800px;
  background-size: contain;
  background-repeat: no-repeat;
  background-position: center;
  /* background-attachment: fixed;  /* Also you didnt close this comment */
}

添加一些样式后，背景图像消失
