我试图为图像(宽度:100%)和固定高度做一个全宽度的自举轮播,但是如果我将宽度设置为100%,则自动高度也会达到100%
我不确定问题是否在我的档案中
<div id="myCarousel" class="carousel slide">
<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>
</ol>
<!-- Carousel items -->
<div class="carousel-inner">
<div class="active item">
<%= image_tag "slider/slide-bg-1.jpg", class: "tales" %>
</div>
<div class="item">
<%= image_tag "slider/slide-bg-2.jpg", class: "tales" %>
</div>
<div class="item">
<%= image_tag "slider/slide-bg-3.jpg", class: "tales" %>
</div>
</div>
<!-- Carousel nav -->
<a class="carousel-control left" href="#myCarousel" data-slide="prev">‹</a>
<a class="carousel-control right" href="#myCarousel" data-slide="next">›</a>
和我的css文件
.tales {
width: 100%;
height: 200px;
}

您是否想让它变得敏感?如果你那么我会推荐以下内容:
.tales {
width: 100%;
}
.carousel-inner{
width:100%;
max-height: 200px !important;
}
但是,响应性地处理此问题的最佳方法是使用类似的媒体查询:
/* Smaller than standard 960 (devices and browsers) */
@media only screen and (max-width: 959px) {}
/* Tablet Portrait size to standard 960 (devices and browsers) */
@media only screen and (min-width: 768px) and (max-width: 959px) {}
/* All Mobile Sizes (devices and browser) */
@media only screen and (max-width: 767px) {}
/* Mobile Landscape Size to Tablet Portrait (devices and browsers) */
@media only screen and (min-width: 480px) and (max-width: 767px) {}
/* Mobile Portrait Size to Mobile Landscape Size (devices and browsers) */
@media only screen and (max-width: 479px) {}

如果您使用 bootstrap 4 Alpha并且Chrome中的图片高度出错,我有一个解决方案: bootstrap 4的文档说明了这一点:
<?php
if( isset($_POST['command']))
{
$command = $_POST['command'];
echo 'Hello ' . $command . "\n";
}
?>
<form method="post">
Subject: <input type="text" name="command"> <br>
</form>
<强>解决方案:强>
解决方案是将&#34; div&#34;围绕图像,使用类&#34; .container&#34;,像这样:
<div id="carouselExampleSlidesOnly" class="carousel slide" data-ride="carousel">
<div class="carousel-inner" role="listbox">
<div class="carousel-item active">
<img class="d-block img-fluid" src="..." alt="First slide">
</div>
<div class="carousel-item">
<img class="d-block img-fluid" src="..." alt="Second slide">
</div>
<div class="carousel-item">
<img class="d-block img-fluid" src="..." alt="Third slide">
</div>
</div>
</div>

我推荐以下Bootstrap 3
.carousel-inner > .item > img,
.carousel-inner > .item > a > img {
min-height: 500px; /* Set slide height here */
}

我知道这是一个较老的帖子,但Bootstrap仍然活着并且踢!
与@ Eduardo的帖子略有不同,我不得不修改:
#myCarousel.carousel.slide {
width: 100%;
max-width: 400px; !important
}
当我仅修改.carousel-inner {}
时,实际图片的大小是固定的,但左/右控件显示错误地显示在div
的一侧。

嘿伙计我有同样的问题,
当我的幻灯片向左移动时,我的身高变为原来的高度,(在响应式网站中)
所以我只用CSS修复它:
.carousel .item.left img{
width: 100% !important;
}
答案 5 :(得分:0)
我发现,如果您只是想更改图像所占元素的高度,这将是有帮助的代码
.carousel-item {
height: 600px !important;
}
但是,这不会使图像的大小动态变化,只会将图像裁剪到其大小。

我创建了一个对我来说效果很好的响应式样本,并且发现旋转木马填充非常简单:
.carousel-fill {
height: -o-calc(100vh - 165px) !important;
height: -webkit-calc(100vh - 165px) !important;
height: -moz-calc(100vh - 165px) !important;
height: calc(100vh - 165px) !important;
width: auto !important;
overflow: hidden;
display: inline-block;
text-align: center;
}
.carousel-item {
text-align: center !important;
}
我的导航高度+页脚小于165px,所以该值对我有效。取一个适合您的值,我从引导程序中覆盖了.carousel-item,因此请确保视频居中。
我的轮播看起来像这样,请注意视频标记上的“轮播填充”。

如果有人需要像我一样控制视频,我会像这样开始和停止视频:
<script language="JavaScript" type="text/javascript">
$(document).ready(function () {
$('.carousel').carousel({ interval: 8000 })
$('#myCarousel').on('slide.bs.carousel', function (args) {
var videoList = document.getElementsByTagName("video");
switch (args.from) {
case 0:
videoList[0].pause();
break;
case 1:
videoList[1].pause();
break;
case 2:
videoList[2].pause();
break;
}
switch (args.to) {
case 0:
videoList[0].play();
break;
case 1:
videoList[1].play();
break;
case 2:
videoList[2].play();
break;
}
})
});
</script>
