我看过很多类似的问题,但解决方案并不适用。
我正在尝试制作一个Bootstrap轮播,以便在调整窗口大小时,图像保持居中,同时保持所需的图像高度和最小100%宽度属性。
这有点难以解释,但您可以在http://www.lyft.com
上看到类似的概念我在codepen上复制了一个类似的问题,你可以看到,如果你将窗口缩小到移动设备的大小,图像仍然是固定的,最终你会看到左上角图像的一角(通常是云或一些无法识别的模糊)。
我试图让这个图像向左移动并保持居中,因为水平视图会缩小,以便图像保持相关。
我的其他旋转木马风格:
/* CUSTOMIZE THE CAROUSEL
-------------------------------------------------- */
/* Carousel base class */
.carousel {
height: 500px;
margin-bottom: 60px;
overflow: hidden;
}
/* Since positioning the image, we need to help out the caption */
.carousel-caption {
z-index: 10;
}
/* Declare heights because of positioning of img element */
.carousel .item {
height: 500px;
background-color: #777;
}
.carousel-inner > .item > img {
position: relative;
top: 0;
left: 0;
min-width: 100%;
max-width: none;
height: auto;
}
.carousel-inner img{
margin: auto;
}
#mycarousel{
position: relative;
top: 0;
}
简单的旋转木马:
<div id="mycarousel" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#mycarousel" data-slide-to="0" class="active"></li>
<li data-target="#mycarousel" data-slide-to="1"></li>
<li data-target="#mycarousel" data-slide-to="2"></li>
<li data-target="#mycarousel" data-slide-to="3"></li>
<li data-target="#mycarousel" data-slide-to="4"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active">
<img src="https://unsplash.it/2000/1250?image=397" data-color="lightblue" alt="First Image">
</div>
<div class="item">
<img src="https://unsplash.it/2000/1250?image=689" data-color="firebrick" alt="Second Image">
</div>
<div class="item">
<img src="https://unsplash.it/2000/1250?image=675" data-color="violet" alt="Third Image">
</div>
<div class="item">
<img src="https://unsplash.it/2000/1250?image=658" data-color="lightgreen" alt="Fourth Image">
</div>
<div class="item">
<img src="https://unsplash.it/2000/1250?image=638" data-color="tomato" alt="Fifth Image">
</div>
</div>
</div>

我根据您在帖子中链接的lyft网站提出了解决方案。我将您的img
转换为div
并使用了背景图片,然后进行了相应的样式设计。
<div class="carousel-inner" role="listbox">
<div class="item active">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=397');" data-color="lightblue" alt="First Image"></div>
</div>
<div class="item">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=689');" data-color="firebrick" alt="Second Image"></div>
</div>
<div class="item">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=675');" data-color="violet" alt="Third Image"></div>
</div>
<div class="item">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=658');" data-color="lightgreen" alt="Fourth Image"></div>
</div>
<div class="item">
<div class="item-child" style="background-image: url('https://unsplash.it/2000/1250?image=638');" data-color="tomato" alt="Fifth Image"></div>
</div>
然后删除了这个.carousel-inner > .item > img
并添加了这个CSS:
.carousel-inner .item .item-child {
background-position: top center;
background-size: cover;
position: absolute;
bottom:0;
top: 0;
left: 0;
right:0;
width: 100%;
height: auto;
}
你can see the js.fiddle here如果你想玩它。希望有所帮助。

你去,最容易修复
而不是图像上的最小宽度使用宽度
.carousel-inner > .item > img {
position: relative;
top: 0;
left: 0;
width: 100%;
max-width: none;
height: auto;
}
也像这样投入旋转木马的高度调整
.carousel .item {
height: auto;
background-color: #777;
}
