Pure Css Slider 不能给每张幻灯片添加文字

Question

我一直在尝试修复这个纯粹的 CSS 滑块，但我无法将文本附加到滑块的中心，也无法为每张幻灯片附加自定义文本。我尝试使用绝对位置，但没有成功'不工作。请帮我解决这个问题。谢谢

这是Css

的片段

 .slide {
  list-style: none;
  position: relative;
  float: left;
  margin: 0;
  padding: 0;
  width: 500px;
  height: 100%;
  background: #ccc;
  text-align: center;
  line-height: 300px;
  background-size: cover;
  background-position: 50% 50%;
  color: #fff;
  -webkit-transform: translate3d(0px, 0px, 0px);
  visibility: hidden;
  -webkit-transform-style: preserve-3d;
}

如果要使元素居中，则需要使用 pourcentage。

只需在您的 li 中添加一个标签，即可为每张幻灯片显示不同的文本。

$.global = new Object();

$.global.item = 1;
$.global.total = 0;

$(document).ready(function() 
    {
    
    var WindowWidth = $(window).width();
    var SlideCount = $('#slides li').length;
    var SlidesWidth = SlideCount * WindowWidth;
    
   $.global.item = 0;
    $.global.total = SlideCount; 
    
    $('.slide').css('width',WindowWidth+'px');
    $('#slides').css('width',SlidesWidth+'px');

   $("#slides li:nth-child(1)").addClass('alive');
    
  $('#left').click(function() { Slide('back'); }); 
  $('#right').click(function() { Slide('forward'); }); 
        
  });

function Slide(direction)
    {
   
    if (direction == 'back') { var $target = $.global.item - 1; }
    if (direction == 'forward') { var $target = $.global.item + 1; }  
    
    if ($target == -1) { DoIt($.global.total-1); } 
    else if ($target == $.global.total) { DoIt(0); }  
    else { DoIt($target); }
    
    
    }

function DoIt(target)
  {
   
    var $windowwidth = $(window).width();
    var $margin = $windowwidth * target; 
    var $actualtarget = target+1;
    
    $("#slides li:nth-child("+$actualtarget+")").addClass('alive');
    
    $('#slides').css('transform','translate3d(-'+$margin+'px,0px,0px)');    
    
    $.global.item = target; 
    
  $('#count').html($.global.item+1);
    
  }

body::-webkit-scrollbar { display: none; }

#slide-window
  {
  position:fixed;
  width:100%;
  height:100%;
  overflow:hidden;

  }
.slide span { font-weight:bold; font-size:200%; text-shadow: 0 0 10px #666 }
.alive { visibility:visible; }
