Ich erstelle eine Website mit Bootstrap 5. Im Header der Website verwende ich Carousel von Bootstrap für meinen Header. Karussellbilder ermöglichen auch die Anzeige von Text und Schaltflächen. Ich möchte, dass die Bilder, Texte und Schaltflächen responsiv sind. Ich habe versucht, Medienabfragen zu verwenden, weiß aber nicht, wie das geht.

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。)
