在图像上方滑动滑块文本 [英] Slick slider text on top of images

问题描述

我试图制作一个非常普通的旋转木马，在垂直中间的两侧有两个箭头，图像顶部的中间有一个按钮。尽管箭头和文字都是绝对的，并且具有更高的Z指数，但我无法在图像上显示任何内容。这是我的代码codepen。 http://codepen.io/kathryncrawford/pen/AXmVAz

这里是我的HTML

 < div class =slick-slider> 
< div> 
< img class =img-fluidsrc =http://www.placecage.com/1500/750alt => 
< div class =info> 
< h1 class =slider-heading>标题< / h1> 
< p class =slider-subheading lead>副标题< / p> 
 < p class =down-arrow> 
< a class =btn btn-large btn-down-arrowhref =＃theend> 
< i class =fa fa-chevron-down fa-lgaria-hidden =true>< / i> 
< / a> 
< / p> 
< / div> 
< / div> 
< div> 
< img class =img-fluidsrc =http://www.placecage.com/1500/750alt => 
< / div> 
< div> 
< img class =img-fluidsrc =http://www.placecage.com/1500/750alt => 
< / div> 
< / div> 
  

我的CSS（光滑的css不在这里，但它在codepen中）

  .slick-slider img {/ *保留图片全屏* / 
 width：100％; 
} 
 
 .chevron-container {/ *用于V形臂的完整滑块高度容器* / 
 height：100％; 
位置：绝对; 
 width：100px; 
} 
 
 .slick-right {/ *向右右箭头* / 
右：0; 
 top：0; 
} 
 
 .chevron-container> 。{/ *垂直中心的位置V形* / 
底部：0; 
颜色：白色; 
 font-size：10em; 
身高：1em; 
 margin：auto; 
位置：绝对; 
 top：0; 
 width：5em; 
 z-index：10; 
} 
 
 .slick-slider .info {
颜色：白色; 
位置：绝对; 
宽度：100％; 
身高：100％; 
 top：0; 
剩下：0; 
 line-height：100vh; 
 text-align：center; 
 z-index：10; 
} 
 
 .slick-slider .info> div {
 display：inline-block！important; 
 vertical-align：middle; 
} 
  

而我的JS

< $ p $ jQuery（函数（$）{
$（'。slick-slider'）。slick（{
可访问性：true，
adaptiveHeight：true ，
arrows：true，
infinite：true，
mobileFirst：true，
nextArrow：'< div class =chevron-container slick-right>< i class =fa fa-chevron-rightaria-hidden =true>< / i>< / span>< span class =sr-only>下一个< / span>< / div> ;'，
prevArrow：'< div class =chevron-container>< i class =fa fa-chevron-leftaria-hidden =true>< / i><< ; / span>< span class =sr-only>上一个< / span>< / div>'，
slidesToShow：1
}）;
}）;


解决方案

您必须这样做

  .slick-slide {
 / * ... * / 
位置：相对; 
} 
  

这样 .info 东西知道它应该完全定位到它的父母。

I'm trying to make a pretty normal carousel, with two arrows on either side in the vertical middle, and text with a button in the middle on top of the image. I cannot get anything to appear on top of the image though, even though the arrows and text are all absolute and have a higher z-index. Here's a codepen with my code. http://codepen.io/kathryncrawford/pen/AXmVAz

And here's my HTML

<div class="slick-slider">
    <div>
        <img class="img-fluid" src="http://www.placecage.com/1500/750" alt="">
        <div class="info">
        <h1 class="slider-heading">Heading</h1>
            <p class="slider-subheading lead">Subheading</p>
            <a class="btn btn-large btn-danger" href="">button text</a>
        <p class="down-arrow">
            <a class="btn btn-large btn-down-arrow" href="#theend">
                <i class="fa fa-chevron-down fa-lg" aria-hidden="true"></i>
            </a>
        </p>
        </div>
    </div>
    <div>
        <img class="img-fluid" src="http://www.placecage.com/1500/750" alt="">
    </div>
    <div>
        <img class="img-fluid" src="http://www.placecage.com/1500/750" alt="">
    </div>
</div>

My CSS (the slick css is not included here, but it is in the codepen)

  .slick-slider img { /* keep images full screen */
    width: 100%;
  }

  .chevron-container { /* full slider height container for chevrons */
    height: 100%;
    position: absolute;
    width: 100px;
  }

  .slick-right { /* keeps right arrow to the right */
    right: 0;
    top: 0;
  }

  .chevron-container > .fa { /* positions chevrons in vertical center */
    bottom: 0;
    color: white;
    font-size: 10em;
    height: 1em;
    margin: auto;
    position: absolute;
    top: 0;
    width: 5em;
    z-index: 10;
  }

  .slick-slider .info {
    color: white;
    position: absolute;
    width: 100%;
    height: 100%;
    top: 0;
    left: 0;
    line-height: 100vh;
    text-align: center;
    z-index: 10;
  }

  .slick-slider .info > div {
    display: inline-block !important;
    vertical-align: middle;
  }

And my JS

jQuery(function($){
  $('.slick-slider').slick({
    accessibility: true,
    adaptiveHeight: true,
    arrows: true,
    infinite: true,
    mobileFirst: true,
    nextArrow: '<div class="chevron-container slick-right"><i class="fa fa-chevron-right" aria-hidden="true"></i></span><span class="sr-only">Next</span></div>',
    prevArrow: '<div class="chevron-container"><i class="fa fa-chevron-left" aria-hidden="true"></i></span><span class="sr-only">Previous</span></div>',
    slidesToShow: 1
  });
});

解决方案

You have to do

.slick-slide {
    /* ... */
    position: relative;
}

so that the .info stuff knows it should be absolutely positioned to it's parent.
