Image Metadata & Context

Most JavaScript lightboxes use data-src or hidden attributes to load high-resolution images, which can prevent search engines from associating descriptive text with the actual file. This CSS-first lightbox uses the semantic <figure> and <figcaption> structure inside the modal. This ensures that the high-res image and its description are permanently linked in the DOM for Google Images and Baidu Image Search.

大多数 JavaScript 灯箱使用 data-src 或隐藏属性来加载高分辨率图片，这可能会阻止搜索引擎将描述性文本与实际文件关联。这种CSS 优先灯箱在模态窗口内使用了语义化的 <figure> 和 <figcaption> 结构。这确保了高分辨率图片及其描述在 DOM 中永久关联，有利于谷歌图片和百度图片搜索的收录。

Crawlable Links vs. Event Listeners

Because this gallery uses standard <a href="#id"> anchors, search engine bots can follow the links to discover the full-sized media assets. Unlike JS-based systems that rely on event.preventDefault(), this native approach provides a clear path for spiders to navigate from the thumbnail to the rich media content without executing a single line of script.

由于此画廊使用标准的 <a href="#id"> 锚点，搜索引擎机器人可以顺着链接发现完整尺寸的媒体资产。与依赖 event.preventDefault() 的 JS 系统不同，这种原生方法为爬虫提供了一条从缩略图导航到富媒体内容的清晰路径，而无需执行任何脚本。
