CSS3 Gallery Lightbox

发布于 大漠

这个Gallery Lightbox同样没有使用js脚本代码仅使用了CSS代码实现,这个效果初看有些许复杂,一开始不太清楚其实现原理,但仔细看看代码,还是能整明白的。功能主要依赖于css的选择器,以及配合锚点定位来实现。其中很关键一步是HTML的结构,特别是图片的点击播放效果,顺序不能搞错,不然效果无法实现。不过这个效果有一个致命的缺点,那就是对图片的大小有所限制,无法实现图片的自应大小,如果你够有信心的话,可以尝试一下不限制宽度,能否实现这个效果。另外一点,CSS实现的效果,当然没有js实现的效果那么流畅,不过当作挑战性的学习,还是不错的,你不仿一试。
