无法使Slider具有响应能力

问题描述 投票:1回答:2

This is how i want to look我遇到了一个问题。我正在尝试用响应式图像构建一个全屏图像滑块。我尝试了所有组合:在HTML中添加样式高度:100%,宽度:100%,高度:自动,宽度:自动在CSS中,但似乎没有任何工作。我会告诉你代码可能我做错了什么。我无法添加代码片段,因为它不显示图像,而且它是很多代码和类。这个问题让我发疯,我正在寻找4小时的修复。 This is how my images looks

HTML

<div id="showcase">
    <div id="arrow-left" class="arrow"></div>
    <div id="slider">
      <div class="slide slide1"></div>
      <div class="slide slide2 "></div>
      <div class="slide  slide3"></div>
    </div>
    <div id="arrow-right" class="arrow"></div>
  </div>

CSS

#showcase,
#slider,
.slide-content {
  height: 100vh;
  width: 100%;
  overflow-x: hidden;
}

#showcase {
  position: relative;
  height: 100%;
  width: 100%;
}

.slide {
  width: 100%;
  height: 100%;
}

.slide1 {
  background: url(/Core/img/lazar1.jpg) no-repeat center center/cover;
}

.slide2 {
  background: url(/Core/img/lazar2.jpg) no-repeat center center/cover;
}

.slide3 {
  background: url(/Core/img/lazar3.jpg) no-repeat center center/cover;
}

.arrow {
  cursor: pointer;
  position: absolute;
  top: 50%;
  margin-top: -50px;
  border-style: solid;
}

#arrow-left {
  border-width: 30px 40px 30px 0;
  border-color: transparent blue transparent transparent;
  left: 0;
  margin-left: 30px;
}

#arrow-right {
  border-width: 30px 0 30px 40px;
  border-color: transparent blue transparent blue;
  right: 0;
  margin-right: 30px;
}

要解决此类问题,对于响应式设计,请使用媒体查询。被引用的页面使用某些宽度断点处的媒体查询来减小包含图像的div的高度,以便允许屏幕在宽度方向上缩小,同时仍然显示具有完整宽高比的图像(因为它们是相当宽的图像) 。代码中的示例如下所示:

//HTML
<div id="showcase">
    <div id="arrow-left" class="arrow"></div>
    <div id="slider">
      <div class="slide slide1"></div>
      <div class="slide slide2 "></div>
      <div class="slide  slide3"></div>
    </div>
    <div id="arrow-right" class="arrow"></div>
  </div>

//CSS
#showcase,#slider{
  height:100vh;
  width:100%;
}
.slide{
  width:100vw;
  height:100vh
}
.slide1{
  background:url(http://www.lazarangelov.com/wp-content/uploads/2015/12/lazar3-1920.jpg) no-repeat center center/cover;
}

@media screen and (max-width: 900px) {
  .slide{
    height: 80vh;
  }
}
@media screen and (max-width: 700px) {
    .slide{
    height: 70vh;
  }
}
@media screen and (max-width: 600px) {
    .slide{
    height: 60vh;
  }
}
@media screen and (max-width: 500px) {
    .slide{
    height: 50vh;
  }
}
@media screen and (max-width: 400px) {
    .slide{
    height: 40vh;
  }
}
@media screen and (max-width: 300px) {
    .slide{
    height: 30vh;
  }
}

请注意,这些不是媒体查询的壮观示例,它们只是用于演示机制。

将以下代码添加到“幻灯片”类:

background-size: contain !important;
