BTW，我在Windows的“Edge”浏览器中运行了这个。怎么了？ 这段代码工作正常，直到昨天，但现在css不起作用。在w3schools或codepen中有什么变化吗？有类型吗？请帮忙。
答案 0 :(得分：2)
首先：使用head taq（必填）：
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<title></title>
<link rel="stylesheet" href="">
<style type="text/css" media="screen">
</style>
</head>
第二次：使用这样的样式代码（不是必需的）：
<style type="text/css" media="screen">
</style>
第三次：将;放在css代码的末尾（第6行末尾）（不是必需的）：
body {
background-color: lavenderblush;
}
我希望第二次和第三次为您提供帮助。

它在codepen中正常工作。
你应该尝试硬刷新（ctrl + F5）
OR
清除缓存和Cookie然后加载页面
OR
尝试硬核版本控制，例如在网址中添加?1或?之后的任何内容，然后点击网址。
e.g。
http://<your URL>.html?1
最佳做法是在<head >标记中使用样式和脚本，因为它将在页面之前加载，您将看到最佳设计。如果它没有得到解决，那么上述解决方案将在缓存相关问题时起作用。
在
中使用Style<head>

这可能是一种预感，但你说它一直工作到昨天。尝试清除你的 浏览器缓存。 https://support.microsoft.com/en-us/help/10607/microsoft-edge-view-delete-browser-history 希望这有帮助！

你的错误是你的身体标签背景颜色属性中的分号
body{
background-color: lavenderblush;
}
