我正在使用 Bootstrap 5 制作一個(gè)網(wǎng)站。在網(wǎng)站的標(biāo)題中，我使用 Bootstrap 中的輪播作為我的標(biāo)題。輪播圖像還允許顯示文本和按鈕。我希望圖像、文本和按鈕具有響應(yīng)能力。我嘗試使用媒體查詢，但我不知道該怎么做。

媒體查詢的寫法如下：
@media screen and (min-width: 900px) {
.carousel-inner{
color:#000;
}
}
我發(fā)現(xiàn)在使用bootstrap時(shí)，你需要在最后添加!important才能被讀?。?/p>
@media screen and (min-width: 900px) {
.carousel-inner{
color:#000 !important;
}
}
如果想了解更多關(guān)于媒體查詢的內(nèi)容，請(qǐng)查看這篇文章：https://www.w3schools.com/css/css3_mediaqueries.asp
(顯然，你可能不是想改變字體顏色，這只是一個(gè)例子。)
