如何用图像填充空白



我希望图像填充在页面的列中：-https://i.stack.imgur.com/VtgcW.jpg

我正在尝试重新创建一个网站来测试我的技能该网站是：-https://www.simplesite.com

当我将它分配给body时，它是有效的，但当我将其分配给div时，下面有空白。我已经尝试了很多东西仍然无法摆脱这个空白。任何帮助都将不胜感激HTML:-

首先，您需要背景大小来适应折叠，这意味着将其设置为覆盖(请注意，图像大小应为1920x1080，以看起来很好，而不是像素化(。

添加/更改此：

.contain {
background: url("imgs/starter5.jpg") 50% 0;
background-repeat: no-repeat;
background-size: cover;
}

如果图像很好，它应该填满页面的所有第一页！

您的css几乎不需要修改。请在您的包含类中尝试以下高度属性：

.contain {
background: url(imgs/starter5.jpg) center center;
background-repeat: no-repeat;
height: 100vh;
}
