添加超链接时如何保持图像缩放

Question

我想为图库中的图像添加 hyperlink（以便打开图像的放大版本），同时保持缩略图上的 'zoom' 效果。我试图向第一张图片添加 hyperlink，但缩放不再是运行。如果我的解释不是很好，我深表歉意，我是编码语言的新手！任何帮助都会很棒！

这里是 link 我得到画廊代码的地方，如果它对任何人都有用的话！ https://codepen.io/oknoblich/pen/ELfzd

< script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js" > < /script> <
  script type = "text/javascript" >


  (function() {

    var documentElem = $(document),
      nav = $('nav'),
      lastScrollTop = 0;

    documentElem.on('scroll', function() {
      var currentScrollTop = $(this).scrollTop();

      //scroll down
      if (currentScrollTop > lastScrollTop) nav.addClass('hidden');
      //scroll up
      else nav.removeClass('hidden');

      lastScrollTop = currentScrollTop;
    });
  })();

Answer 1

缩放使用 css 完成并应用于悬停事件，如果您将元素 class 与单击事件的相同规则应用，它将保留 css 属性。

一开始我没有答对，但你还需要更改 CSS，.gallery>div>img 表示紧跟 class gallery 的元素div 紧跟一个 img，要包含 img 和 a 标签，您需要删除 > ".gallery>div img"

Answer 2

这是肯定有效的代码，并且会以大尺寸显示图像。
