將按鈕放在轉盤外面

Question

使用Bootstrap 4，我想在轉盤的左側和右側放置全高按鈕。 輪播應該是最大的元素，因此col-10類的東西的大小很有意義。

這是我到目前為止的內容：

 @media (min-width: 768px) { /* show 3 items */ .carousel-inner .active, .carousel-inner .active + .carousel-item, .carousel-inner .active + .carousel-item + .carousel-item { display: block; } .carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left), .carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left) + .carousel-item, .carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left) + .carousel-item + .carousel-item { transition: none; } .carousel-inner .carousel-item-next, .carousel-inner .carousel-item-prev { position: relative; transform: translate3d(0, 0, 0); } .carousel-inner .active.carousel-item + .carousel-item + .carousel-item + .carousel-item { position: absolute; top: 0; right: -33.3333%; z-index: -1; display: block; visibility: visible; } /* left or forward direction */ .active.carousel-item-left + .carousel-item-next.carousel-item-left, .carousel-item-next.carousel-item-left + .carousel-item, .carousel-item-next.carousel-item-left + .carousel-item + .carousel-item, .carousel-item-next.carousel-item-left + .carousel-item + .carousel-item + .carousel-item { position: relative; transform: translate3d(-100%, 0, 0); visibility: visible; } /* farthest right hidden item must be abso position for animations */ .carousel-inner .carousel-item-prev.carousel-item-right { position: absolute; top: 0; left: 0; z-index: -1; display: block; visibility: visible; } /* right or prev direction */ .active.carousel-item-right + .carousel-item-prev.carousel-item-right, .carousel-item-prev.carousel-item-right + .carousel-item, .carousel-item-prev.carousel-item-right + .carousel-item + .carousel-item, .carousel-item-prev.carousel-item-right + .carousel-item + .carousel-item + .carousel-item { position: relative; transform: translate3d(100%, 0, 0); visibility: visible; display: block; visibility: visible; } }

我嘗試了以下方法，但均未成功：

<button class="col-1">Left button goes here</button>
<div id="myCarousel" class="carousel slide col-10" data-ride="carousel">
  ...
</div>
<button class="col-1">Right button goes here</button>

我怎樣才能做到這一點？

Answer 1

您只需將旋轉木馬和按鈕放在引導欄內即可使用。

如以下格式的示例：

<div class="container-fluid">
    <div class="row">
        <div class="col-1">
            <button class="btn-default">Left button</button>
        </div>
        <div class="col-10">
            <div id="myCarousel" class="carousel slide" data-ride="carousel">
                ....
            </div>
        </div>
        <div class="col-1">
            <button class="btn-default">Right button</button>
        </div>
    </div>
</div>

 @media (min-width: 768px) { /* show 3 items */ .carousel-inner .active, .carousel-inner .active + .carousel-item, .carousel-inner .active + .carousel-item + .carousel-item { display: block; } .carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left), .carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left) + .carousel-item, .carousel-inner .carousel-item.active:not(.carousel-item-right):not(.carousel-item-left) + .carousel-item + .carousel-item { transition: none; } .carousel-inner .carousel-item-next, .carousel-inner .carousel-item-prev { position: relative; transform: translate3d(0, 0, 0); } .carousel-inner .active.carousel-item + .carousel-item + .carousel-item + .carousel-item { position: absolute; top: 0; right: -33.3333%; z-index: -1; display: block; visibility: visible; } /* left or forward direction */ .active.carousel-item-left + .carousel-item-next.carousel-item-left, .carousel-item-next.carousel-item-left + .carousel-item, .carousel-item-next.carousel-item-left + .carousel-item + .carousel-item, .carousel-item-next.carousel-item-left + .carousel-item + .carousel-item + .carousel-item { position: relative; transform: translate3d(-100%, 0, 0); visibility: visible; } /* farthest right hidden item must be abso position for animations */ .carousel-inner .carousel-item-prev.carousel-item-right { position: absolute; top: 0; left: 0; z-index: -1; display: block; visibility: visible; } /* right or prev direction */ .active.carousel-item-right + .carousel-item-prev.carousel-item-right, .carousel-item-prev.carousel-item-right + .carousel-item, .carousel-item-prev.carousel-item-right + .carousel-item + .carousel-item, .carousel-item-prev.carousel-item-right + .carousel-item + .carousel-item + .carousel-item { position: relative; transform: translate3d(100%, 0, 0); visibility: visible; display: block; visibility: visible; } }
