html - 媒体查询没有响应我的样式？在 CSS 文件中导入错误？

所以我有点问题.. 即使它们位于媒体查询代码所在的 CSS 文件中，我的媒体查询也不会响应我的样式。我缩小了范围，发现我的“背景:透明；”在我的媒体查询中不起作用。如果我能正常工作，我的背景图像应该按照我想要的方式工作。

这是我想要的布局，目前我的背景没有响应，所以现在它只是一个大的红色背景，用白色文本覆盖我的图片，这就是它在响应时应该的样子。代码如下。

最佳答案

您的媒体查询格式不正确，缺少大括号。

你有什么

@media (max-width: 767px) /* styling */

你需要什么

@media (max-width: 767px) { /* styling */ }
