后台 CSS 属性 似乎无法正常工作
Background CSS property doesn't seem to work correctly
我是 html 和 css 的新手,我遇到了有关此代码的问题。
基本上 I/m 试图做的是在每个部分的后面放置一个背景图像(图像应该完全适合该部分)。使用这种代码没有任何反应,我可以将颜色更改为 te 部分。路径图像没有错误,所以我有点困惑。

背景图片有问题 url。当你说
background-image: url('asset/background1.png');
您告诉浏览器 css 文件所在的位置,这是它的相对路径。假设 css 文件名为:
- myclasses.css
根据您所说的,包含的文件夹应该如下所示:
- myclasses.css --> 你的 css 文件
- 资产 --> 文件夹
现在 "asset" 文件夹必须包含 background1.png。
我也遇到了图像问题,所以我将 img 和 css 文件放在同一个资产文件夹中。然后在 link css 上 html 只需写“”。对于 css 上的背景图像,只需写 "background-image: your-image.png"。这就是我为管理它所做的。为了使图像完全适合该部分,请在每个部分使用 "background-size: cover"。

背景图片有问题 url。当你说
background-image: url('asset/background1.png');
您告诉浏览器 css 文件所在的位置,这是它的相对路径。假设 css 文件名为:
- myclasses.css
根据您所说的,包含的文件夹应该如下所示:
- myclasses.css --> 你的 css 文件
- 资产 --> 文件夹
现在 "asset" 文件夹必须包含 background1.png。
我也遇到了图像问题,所以我将 img 和 css 文件放在同一个资产文件夹中。然后在 link css 上 html 只需写“”。对于 css 上的背景图像,只需写 "background-image: your-image.png"。这就是我为管理它所做的。为了使图像完全适合该部分,请在每个部分使用 "background-size: cover"。
