html – 移动和平板电脑的图像拉伸问题

问题：在移动版本上,图像在纵向模式下伸展.如下图所示,它看起来很压缩.

在横向模式下,该图像看起来并不像桌面版本那样看起来很漂亮.

我使用引导,图像具有类img响应,它不起作用.

下面是我写的css.我已经尝试设置background-size：contains和一些其他方法,但没有呈现所需的结果.该项目使用Coldfusion和Mura(CMS).

UPDATE

以下css正在用于使其响应：

@media (min-width: 1024px) #homepage .carousel .item img {
  width:100%;
  height:auto;
}
media (min-width:769px) and (max-width:980px) {
  #homepage .carousel .item img {
    max-width: 100%;
    min-height: 100%;
    height: auto;
    margin-top: 154px !important;
  }
}
@media (max-width: 751px) and (orientation: landscape) {
  .override-hidden-xs1 {
    display: block;
  }
  .carousel-inner {
    width: 100% !important;
  }
  .fixNext {
    margin-right: 0px;
  }
  .carouselCaption {
    margin-top: 120px !important;
  }
  .h4Font {
    font-size: 16px !important;
  }
  .upcoming-events-image {
    max-width: 180px;
    max-height: 180px;
    width: 22% !important;
    margin-left: 340px !important;
  }
  .image-margin-top {
    margin-top: 170px !important;
    display: inline-block;
  }
}
@media (max-width: 767px) {
  #homepage .carousel .item {
    height: 200px;
    margin-top: 241px;
  }
  #homepage .carousel .item img {
    max-width: 100%;
    height: auto;
    display: block;
  }
}
@media (max-width: 767px) and (orientation: landscape) {
  #homepage .carousel .item {
    height: 200px;
    margin-top: 311px;
  }
}
@media (min-width: 768px) and (max-width: 980px) {
  .company-logo {
    width: 400px;
  }
  #homepage .carousel .item img {
    /*max-width: 1200px;*/
    max-width: 100%;
    min-height: 100%;
    padding-top: 162px;
  }
  #homepage .carousel .carousel-caption {
    margin-left: 64px;
  }
  .image-margin-top {
    margin-top: 57px !important;
  }
  .changePosition {
    margin-top: -193px !important;
  }
}
@media (min-width: 920px) {
  .company-logo {
    width: 400px;
  }
  #homepage .carousel .item img {
    /*max-width: 1200px;*/
    max-width: 100%;
    min-height: 100%;
  }
}

以下是ColdFusion代码,它会从CMS调用图像：

<div class="row carousel-inner padding-topImage">
  <cfset local.iterator.reset()>
    <cfset local.idx=0>
      <cfloop condition="local.iterator.hasNext()">
        <cfset local.item=iterator.next()>
          <cfif ListFindNoCase( 'jpg,jpeg,gif,png',ListLast(local.item.getImageURL(),'.'))>
            <div class="row item img-responsive<cfif local.idx eq 0> active</cfif>">
              <img src="#local.item.getImageURL(argumentCollection=local.imageArgs)#" alt="#HTMLEditFormat(local.item.getTitle())#">
              <cfif arguments.showCaption>
                <div class="container">
                  <div class="carousel-caption carousel-caption1">
                    <div>
                      <!--- <h3><a href="#local.item.getURL()#">#HTMLEditFormat(local.item.getTitle())#</a></h3> --->
                      <div class="visible-xs">
                        <!---<h2>#HTMLEditFormat(local.item.getTitle())#</h2>--->
                      </div>
                      <div class="hidden-xs">#local.item.getSummary()#
                        <!--- #local.item.getBody()# --->
                        <!---<p><a class="btn btn-larg btn-primary" href="#local.item.getURL()#">Read More</a></p>--->
                      </div>
                      <!---<div class="override-hidden-xs1 carouselCaption" style="color:##000"><span class="h4Font">#HTMLEditFormat(local.item.getTitle())#</span>
                                                </div>--->

                    </div>
                  </div>
                </div>
              </cfif>
            </div>
            <cfset local.idx++>
          </cfif>
      </cfloop>
</div>

UPDATE

这是我遇到的问题,但我无法解决.

高度是固定的,所以我尝试高度：自动,但转盘中的图像消失.

如何修改css,以使背景高度依赖于基于屏幕尺寸调整大小的图像.

这是修改后的css：

@media (max-width: 747px){
	#homepage .carousel .item img{
		margin-top: 71px !important;
		max-width:0px;
		min-height:0%;
	}/*
	#homepage .carousel .item {
		height:180px !important;
	}*/
	.carousel-inner {
		height:auto;
	}
}
@media (min-width: 748px){
	#homepage .carousel .item img{
		max-width:0px;
		min-height:0%;
	}/*
	#homepage .carousel .item {
		height:180px !important;
	}*/
}

@media (max-width: 1024px) and (min-width: 768px){
	#homepage .carousel .item {
		width: 100% !important;
		/*margin-top: 20px !important;*/
		height:396px !important;
	}
}

/*@media (min-width:992px) and (max-width:1363px){
	#homepage .carousel .item img {
		/* width: 100% !important; 
		margin-top: 15px !important;
		max-height: auto;
		max-height: 100%;
		min-height: 80%;
	}
}

由于固定的高度,以下是移动和平板电脑版本.我已经尝试删除引起问题的项目类,但是如上所述,它使得转盘消失

任何帮助将不胜感激

解决方法

根据经验,您不应指定任何转盘组件的高度或将其设置为自动,这些组件中的[max / min] -height：100％是什么导致拉伸的原因

.carousel-inner {
   height:auto;
  }

.carousel .item {
    height: auto;
}

.carousel .item img {
    height:auto;

}

这个概念不仅适用于转盘.设计课程时,保持高度不变或自动.

例如：

.give-me-the-bounty
{
    width: 100%;
    height:auto;
}
