Question

目前，我正在使用Materialisecss Image Slider。实际上我想要的是保持一个固定的全屏背景图像，文本和图像在固定的背景图像上滑过。

现在，我将滑块类的背景颜色设置为透明，但它不起作用。

$(document).ready(function(){
  $('.slider').slider();
});

 section {
   background: url('http://lorempixel.com/580/250/nature/4') center center no-repeat;
  background-size: cover;
}


.slider .slides {
 background-color: rgba(255,255,255,0);
  margin: 0;
  height: 400px;
}

最后，我找到了我的问题的答案。

function step(n){
 //$(".content-switcher").hide();
  if(n==1){
    $(".content-switcher").animate({
      "left":"-600px"
    },"slow");
  } else if(n==2){
    $(".content-switcher").animate({
      "left":"-1200px"
    },"slow");
  } else if(n==3){
    $(".content-switcher").animate({
      "left":"0px"
    },"slow");
  }
}

.container{
  width: 600px;
  margin: 0 auto;
  outline:1px solid red;
  overflow: hidden;
  background-image: url("https://static.vecteezy.com/system/resources/previews/000/093/696/original/vector-yellow-abstract-background.jpg");
}
.slider{ width: 1800px;}
.content-switcher{
  width: 600px;
  float: left;
  position: relative;
  top:0;
  left: 0;
}

Answer 2

如果您处理section style属性中的引用问题，似乎可以正常工作。如果您对style=""使用双引号，则在这些双引号内不能使用双引号。因此，您需要删除该属性中的双引号或用单引号替换它们。另外rgba(255,255,255,0)是实现透明度的一种方法，但更简单的方法是使用transparent - 但更简单的方法就是完全删除该行，因为默认情况下没有背景，所以它＆＃39} ;透明。这是一个有效的演示 - http://codepen.io/anon/pen/MJwOBR

Answer 3

您可以使用带有覆盖类的div并在整个图像上设置覆盖div，如下所示：

在div之后添加<section> tag，并将类名设为class="overlay"

<div class="overlay"></div>

添加一些CSS，以在图片上设置覆盖div

 .overlay
   {    
    position: absolute;
    height: 100%;
    width: 100%;
    background-color: rgba(255, 255, 255, 0.17);
   }

并添加CSS以正确显示文本

.caption {
position: relative;
z-index: 99;
}

尝试一下。
