我想根据这个做一个工作的carousell。 http://v4-alpha.getbootstrap.com/examples/carousel/ 问题是,当我上传我的图像并将其调整到一个小屏幕尺寸时,我得到了图像下的旧图像库的一部分,就像这里一样。 https://postimg.org/image/ocul5jt2t/ 我想要的只是我的图像到位,仅此而已。有人可以帮帮我吗?
<!-- Carousel

carousel html是相同的,也是它的css 我想让它适应我的项目,但正如我之前提到的,我将它调整到一个小尺寸时会遇到问题。如果你注意到这张照片,你可以很好地了解它的错误。
body {
padding-bottom: 3rem;
color: #5a5a5a;
}
.carousel {
margin-bottom: 4rem;
}
.carousel-caption {
z-index: 10;
}
.carousel-item {
height: 32rem;
background-color: #777;
}
.carousel-item > img {
position: absolute;
top: 0;
left: 0;
min-width: 100%;
height: 32rem;
}
.carousel-indicators {
top: 1.5rem;
right: 1.5rem;
bottom: auto;
left: auto;
width: 1rem;
margin-left: 0;
}
.carousel-indicators > li {
margin-bottom: .25rem;
}
@media (min-width: 40em) {
.carousel-caption p {
margin-bottom: 1.25rem;
font-size: 1.25rem;
line-height: 1.4;
}
.featurette-heading {
font-size: 50px;
}
}
@media (min-width: 62em) {
.featurette-heading {
margin-top: 7rem;
}
}

这是BS 4 alpha的一个已知问题:https://github.com/twbs/bootstrap/pull/18258
一种选择是隐藏较小视口上的标题,这可以使用hidden-sm-down
来完成。我发现的另一种解决方法是在图片上使用object-fit:cover
,但旧浏览器不支持此功能。
.carousel-item > img {
position: absolute;
top: 0;
left: 0;
min-width: 100%;
min-height: 32rem;
object-fit: cover;
}
