图像顶部的光滑滑块文本

Question

我正在尝试制作一个非常正常的旋转木马，垂直中间两侧各有两个箭头，图像顶部中间有一个按钮。 尽管箭头和文本都是绝对的并且具有更高的z-index，但我无法在图像上显示任何内容。 这是我的代码的代码。 http://codepen.io/kathryncrawford/pen/AXmVAz

这是我的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>

我的CSS（光滑的css不包括在这里，但它在codepen中）

  .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;
  }

而我的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
  });
});

Answer 1

你必须做

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

所以.info东西知道它应该绝对定位于它的父级。

Answer 2

只需添加position: relative对于.slide-slide 。

 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 }); }); 

 .slick-slider { position: relative; display: block; box-sizing: border-box; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; -webkit-touch-callout: none; -khtml-user-select: none; -ms-touch-action: pan-y; touch-action: pan-y; -webkit-tap-highlight-color: transparent; } .slick-list { position: relative; display: block; overflow: hidden; margin: 0; padding: 0; } .slick-list:focus { outline: none; } .slick-list.dragging { cursor: pointer; cursor: hand; } .slick-slider .slick-track, .slick-slider .slick-list { -webkit-transform: translate3d(0, 0, 0); -moz-transform: translate3d(0, 0, 0); -ms-transform: translate3d(0, 0, 0); -o-transform: translate3d(0, 0, 0); transform: translate3d(0, 0, 0); } .slick-track { position: relative; top: 0; left: 0; display: block; } .slick-track:before, .slick-track:after { display: table; content: ''; } .slick-track:after { clear: both; } .slick-loading .slick-track { visibility: hidden; } .slick-slide { display: none; float: left; position: relative; height: 100%; min-height: 1px; } [dir='rtl'] .slick-slide { float: right; } .slick-slide img { display: block; } .slick-slide.slick-loading img { display: none; } .slick-slide.dragging img { pointer-events: none; } .slick-initialized .slick-slide { display: block; } .slick-loading .slick-slide { visibility: hidden; } .slick-vertical .slick-slide { display: block; height: auto; border: 1px solid transparent; } .slick-arrow.slick-hidden { display: none; } .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; }
