/* ==========================================================================
   NZEP 资料库 · assets/gallery.css —— 图库页（gallery.html）专用样式
   --------------------------------------------------------------------------
   为什么不写进 nzep.css：那一份是全站共用的**基础样式**，改了所有页面都会受影响
   （而且它是 GBK 编码的，往里加 UTF-8 中文注释会把整个文件搅乱）。
   所以图库这一页的样式全部放这里，只被 gallery.html 引用。

   版式：瀑布流（CSS multi-column，纯 CSS，没有 JS 测高），
   卡片的图片按上传时记下的宽高算 aspect-ratio —— 图还没加载时位置就是对的，
   加载完不会把下面的卡片顶下去（这是瀑布流最容易被用户骂的"跳一下"）。

   手机（≤767px）：两列；平板：三列；宽屏：四列。
   所有可点元素不小于 40×40（用户在手机上点得到）。
