Question

上下文 - 我找到了Book设计的编写器。 codepen只能打开书籍封面并显示第1页。我想检查是否可以翻页并显示后续页面（第2页，第3页）。我能够翻页，但翻页的书被封面覆盖了。在开发人员工具中，我将翻页的z-index更改为高于书籍封面，但没有更改。

请参阅codepen链接 - http://codepen.io/tusharsaurabh/pen/wgRzdg

期望 - 当我翻页时，翻页不应被封面隐藏。

以下是代码段 -

    $(function(){
	var book = $('#book');
	$('#view-cover').click(function(){
		$(this).addClass('cur').siblings().removeClass('cur');
		book.removeClass().addClass('view-cover');
	});
	$('#view-back').click(function(){
		$(this).addClass('cur').siblings().removeClass('cur');
		book.removeClass().addClass('view-back');
	});
	$('#open-book').click(function(){
		if ( book.attr('class') !='open-book') {
			$(this).addClass('cur').siblings().removeClass('cur');
			book.removeClass().addClass('open-book');
		}else{
			$(this).removeClass('cur');
			$('#view-cover').addClass('cur');
			book.removeClass().addClass('view-cover');
		}
	});
	$('#view-rotate').click(function(){
		$(this).addClass('cur').siblings().removeClass('cur');
		book.removeClass().addClass('view-rotate');
	});
    $('#page-turn').click(function(){
      $(this).addClass('cur').siblings().removeClass('cur');
      $('#book-page-turn').addClass('page-turn');
      $('#book-page-turn').css('z-index','20');
    });
    });

Answer 1

我不认为z-index是问题所在。由于transform

上的backface-visibility和.page-turn样式，页面未显示

删除这些：

 /*-webkit-transform: rotate3d(0, 1, 0, -160deg);
  -moz-transform: rotate3d(0, 1, 0, -160deg);
  -ms-transform: rotate3d(0, 1, 0, -160deg);
  -o-transform: rotate3d(0, 1, 0, -160deg);
  transform: rotate3d(0, 1, 0, -160deg);

  -webkit-backface-visibility: hidden;
  -moz-backface-visibility: hidden;
  -ms-backface-visibility: hidden;
  -o-backface-visibility: hidden;
  backface-visibility: hidden;*/

然后运行代码：
