我正在使用 Bootstrap 5 制作一个网站。在网站的标题中，我使用 Bootstrap 中的轮播作为我的标题。轮播图像还允许显示文本和按钮。我希望图像、文本和按钮具有响应能力。我尝试使用媒体查询，但我不知道该怎么做。

媒体查询的写法如下：

@media screen and (min-width: 900px) {
 .carousel-inner{
  color:#000;
  }
}

我发现在使用bootstrap时，你需要在最后添加!important才能被读取：

@media screen and (min-width: 900px) {
 .carousel-inner{
  color:#000 !important;
  }
}

如果想了解更多关于媒体查询的内容，请查看这篇文章：https://www.w3schools.com/css/css3_mediaqueries.asp

(显然，你可能不是想改变字体颜色，这只是一个例子。)
