Bootstrap圖像旋轉木馬文本/指標在小屏幕上丟失

我有一個在大屏幕上很好的Bootstrap旋轉木馬，但如果我縮小屏幕尺寸，指標會移動到圖像下方，我完全失去標題文字。我肯定錯過了什麼。我想要在整個圖像上顯示指標和文字，就像更大的屏幕一樣。任何幫助讚賞...Bootstrap圖像旋轉木馬文本/指標在小屏幕上丟失

這裏是我的CSS是否有幫助.carousel { \t保證金左：-15px; \t margin-right：-15px; } .carousel-inner { \t height：400px; } .carousel-caption { \t padding-bottom：450px; } .carousel-control { \t margin：200px 0; } – James

https://bootsnipp.com/snippets/featured/simple-responsive-carousel這是一個Bootstrap響應旋轉木馬的例子。你有CSS和HTML代碼。 – F0XS

這是因爲輪播中的圖像獲取調整大小時，根據其縱橫比調整大小。

刪除.carousel-control { margin: 200px 0; }和.carousel-caption，而不是padding-bottom給bottom在%並根據media queries您的要求進行調整。

而且添加該css

.carousel-inner .item{ 
    height: 100%; 
} 
.carousel-inner .item img { 
    width: 100%; 
    height: 100% !important; 
    object-fit: cover; 
}

.carousel { margin-left: -15px; margin-right: -15px; } 
 
.carousel-inner{ height: 400px; } 
 
.carousel-caption { bottom: 30% !important; } 
 
.carousel-inner .item{ 
 
    height: 100%; 
 
} 
 
.carousel-inner .item img { 
 
    width: 100%; 
 
    height: 100% !important; 
 
    object-fit: cover; 
 
}

謝謝！似乎完美地工作。我永遠不會有我自己的！乾杯。 – James

實際上，我可以問一下......這使得大屏幕上的圖像填充頁面，而我希望高度更小。試圖改變CSS，但沒有任何反應，有什麼想法？ – James

對不起，我不清楚你的問題。意味着您希望圖像具有100％的屏幕寬度和限制的高度？ –
