Im trying to do a bootstrap carousel with full width for the images (width: 100%) and a fixed height but if I set the width to 100% the height automacally is taking the 100% too

I don't sure if the problem is in my files

 <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">&lsaquo;</a>
<a class="carousel-control right" href="#myCarousel" data-slide="next">&rsaquo;</a>

and my css file

.tales {
  width: 100%;
  height: 200px;
}

你想让它响应吗？如果你是那么我只推荐以下内容：

.tales {
  width: 100%;
}
.carousel-inner{
  width:100%;
  max-height: 200px !important;
}

但是，响应式处理此问题的最佳方法是使用以下媒体查询：

/* 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 中图像的高度有错误，我有一个解决方案：bootstrap 4 的文档说： 

<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>

解决方案：

解决方案是将“div”放在图像周围，使用“.container”类，如下所示：

<div class="carousel-item active">
  <div class="container">
    <img src="images/proyecto_0.png" alt="First slide" class="d-block img-fluid">
  </div>
</div>

我为 Bootstrap 3 推荐以下内容

.carousel-inner > .item > img,
.carousel-inner > .item > a > img {
  min-height: 500px;    /* Set slide height here */

}

我知道这是一篇较旧的帖子，但 Bootstrap 仍然活跃且充满活力！

与@Eduardo 的帖子略有不同，我不得不修改：

#myCarousel.carousel.slide {
    width: 100%; 
    max-width: 400px; !important
}

当我只修改.carousel-inner {}时，实际图像是固定大小的，但左/右控件在div.

我有同样的问题。

当我的幻灯片向左移动时，我的高度变为原来的高度，（在响应式网站中）

所以我只用 CSS 修复了它：

.carousel .item.left img{
    width: 100% !important;
}

我创建了一个适合我的响应式示例，我发现它非常简单，看看我的轮播填充：

.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 165 像素，因此该值对我有用。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，请注意视频标签上的“carousel-fill”。

<div>
        <div id="myCarousel" class="carousel slide carousel-fade text-center" 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>
            </ol>

            <!-- Wrapper for slides -->
            <div class="carousel-inner">
                <div class="carousel-item active">
                    <video autoplay muted class="carousel-fill">

                <span class="sr-only">Next</span>
            </a>
        </div>
    </div>

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>

我发现如果您只想更改图像占据的元素的高度，这将是有用的代码。

.carousel-item {
    height: 600px !important;
}

但是，这不会使图像的大小动态化，它只会将图像裁剪为其大小。

只需将 height="400px" 放入图像属性中，例如

<img class="d-block w-100" src="../assets/img/natural-backdrop.jpg" height="400px" alt="First slide">
