Question

我有轮播滑块，该滑块连续有4张图像，在台式机和平板电脑的屏幕尺寸上还可以，但是在移动设备上，我不想调整图像的尺寸，所以我只想在每张幻灯片中显示一个项目。引导程序会自动调整图像大小并显示较小的项目！如何检测移动屏幕的尺寸，并在每张幻灯片中仅显示一张图像。

我的代码：

<style>
.media-carousel 
{
  margin-bottom: 0;
  padding: 0 40px 30px 40px;
  margin-top: 30px;
}
/* Previous button  */
.media-carousel .carousel-control.left 
{
  left: -12px;
  background-image: none;
  background: none repeat scroll 0 0 #222222;
  border: 4px solid #FFFFFF;
  border-radius: 23px 23px 23px 23px;
  height: 40px;
  width : 40px;
  margin-top: 30px
}
/* Next button  */
.media-carousel .carousel-control.right 
{
  right: -12px !important;
  background-image: none;
  background: none repeat scroll 0 0 #222222;
  border: 4px solid #FFFFFF;
  border-radius: 23px 23px 23px 23px;
  height: 40px;
  width : 40px;
  margin-top: 30px
}
/* Changes the position of the indicators */
.media-carousel .carousel-indicators 
{
  right: 50%;
  top: auto;
  bottom: 0px;
  margin-right: -19px;
}
/* Changes the colour of the indicators */
.media-carousel .carousel-indicators li 
{
  background: #c0c0c0;
}
.media-carousel .carousel-indicators .active 
{
  background: #333333;
}
.media-carousel img
{
  width: 250px;
  height: 100px
}
</style>

  <div class="carousel slide media-carousel" id="media">

Answer 1

无法使用引导旋转带根据屏幕分辨率调整幻灯片，而需要使用外部来源制作这种类型的困难滑块。

这是参考链接，可帮助您制作这种类型的滑块。
