Question

我正在尝试创建响应式轮播，但是图片的宽度和高度不同，并且由于移动版本而无法使用像素。

    <a class="left carousel-control" href="#myCarousel" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#myCarousel" data-slide="next">
      <span class="glyphicon glyphicon-chevron-right"></span>
      <span class="sr-only">Next</span>
    </a>

Answer 1

我建议您尝试避免使用内嵌样式。您如何尝试使用：

procedure Test;
var
  iBaseClass : TBaseClass;
  iStringStuff : TStringStuff;
  iNumStuff : TNumStuff;
begin
  iBaseClass := TBaseClass.Create;
  iStringStuff := TStringStuff.Create;
  iNumStuff := TNumStuff.Create;
end;

用于增加图像的宽度。

也许添加

.item img{
width: 100%;
}

转盘。

Answer 2

尝试使用此方法添加不同大小的图像，以固定的height:500px

进行查看

.carousel-inner .item{
height:500px;
background-size:cover;
background-position: center center;
}

      <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" role="listbox">
      <div class="item active" style="background-image: url(//placehold.it/1024x700)  ">
      </div>

      <div class="item" style="background-image: url(//placehold.it/100x100)  ">
      </div>

      <div class="item" style="background-image: url(//placehold.it/1024x700)  ">
      </div>

      <div class="item" style="background-image: url(//placehold.it/200x200)  ">
      </div>
    </div>

    <!-- Left and right controls -->
    <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
