- posts/_index.md 和 posts/index.md的区别 1. _index.md默认是列表页面（branch bundle）对应的layout是 list.html,index.md（leaf bundle）对应的layout是 single.html - 默认对应模板就是layouts/_default/list.html 和layouts/_default/single.html - 如果自定义模板可以{theme}/layouts/posts/list.html {theme}/layouts/posts/single.html - 也可以直接在layouts/posts/list.html 和/layouts/posts/single.html 网站的模板优先级别高于主题模板
