Question

我有带文本滑块的bootstrap轮播，我有指标问题，因为如果文字大或小，我的指标没有固定的位置。我试图为 carousel 类设置有限的高度，这仅适用于计算机，但对移动设备没有响应，我删除了高度。

只需在min-height元素上设置carousel-inner即可使指标保持在同一位置。

最简单的方法是将其添加到CSS中：

.carousel-inner {
  min-height: 120px;
}

但问题是，每当窗口大小发生变化时，carousel-inner内的项目大小也会发生变化，其高度可能超过120px。

更好的方法是获取具有最大高度的项目，然后动态添加min-height属性。这是一个例子：

$(function () {

  // Reference your carousel-inner and the items.
  var $carouselnner = $(".carousel-inner"),
      $carouselItems = $carouselnner.find('.item');

  // Handle window resize.
  function resizeHandler() {

    // Map over all items to get their height and assign it to minHeight.
    var minHeight = $carouselItems.map(function () {
      return $(this).height();
    }).get();

    // Now let's apply the biggest height as the value of min-height on carousel-inner.
    $carouselnner.css('min-height',  Math.max.apply(null, minHeight) + 10 + 'px');

  }

  // Add a listener to window resize and trigger it immediately.
  $(window).resize(resizeHandler).trigger('resize');

});

.services h2 {
  margin-top: 97px;
}
.carousel-indicators li {
  background-color: transparent;
  border: 2px solid #dbdbdb !important;
}
.carousel-indicators .active {
  background-color: #3eb8df !important;
  border: 2px solid #3eb8df !important;
}
.carousel-indicators {
  bottom: -60px !important;
}
.carousel-indicators li {
  width: 15px !important;
  height: 15px !important;
}

.carousel-inner {
  min-height: 120px;
}
