在@media 中嵌套@keyframe

Question

我必须修复一个带有大括号的错误。但是所有的左括号都有一对。第212行有错误

Expected RBRACE at line 212, col 2. @-webkit-keyframes move {

但是当我测试 212 之前和 212 之后的代码时 - 没有看到错误。

由于这个错误，验证器无法在@media 中看到壁橱支架。

Answer 1

根据 W3C 规范：

At-rules inside @media are invalid in CSS2.1.

参考：www.w3.org - Media types

所以这行不通：

@media (max-width: 768px) {

   @media (max-width: 450px) {

   }

}

这也不会:

@media (max-width: 768px) {

   @-webkit-keyframes animation {

   }

}

关键帧动画应在任何媒体类型之外声明，然后在必要时在适用或相关媒体查询中应用。

在@media 中嵌套@keyframe
