我的 CSS 文件不响应 HTML 文件。我已经在我的 HTML 文件中导入了 CSS 文件,并且这两个文件都在同一个目录中。当我的 CSS 和 HTML 写在同一个文件中时,它以前有效。但是,当我尝试分离这两个文件时,CSS 文件没有响应。

您在 CSS 文件中使用了 HTML 语法。
您必须替换以下语法:
<head><style>body {
background-color: lightblue;
}
...
...
...
</style></head>
与:
body{
background-color: lightblue;
}
...
...
...
/* remove the closing tags*/
