To access variables from a specific page on your site, you can reference it using its slug: site.pages['your-slug']
For example, we could grab the title and body from our /about page and re-use it somewhere else in our site:
{% assign about_page = site.pages['about'] %}
<h2>{{ about_page.title }}</h2>
{{ about_page.body }}
Here’s a quick shorthand version if you only need to access a single variable:
{{ site.pages['about'].body }}
You can also reference nested pages:
site.pages['about'].pages - gets all nested pages under /about/*site.pages['about'].pages['team'] - gets the nested page /about/teamPosts can be accessed in a similar way, using posts instead of pages:
site.posts['hello-world'] - looks for post in any page /*/hello-worldsite.pages['blog'].posts - gets all blog posts under /blog/*site.pages['blog'].posts['hello-world'] - gets the post /blog/hello-worldsite.pages['blog'].taxonomy['tags']['featured'].posts - gets posts tagged “featured”For flexibility in your theme you can reference content relative to the current page:
pages['your-slug'] - gets child page under current pageparent.pages - gets all sibling pages from parent pageparent.pages['your-slug'] - gets sibling from parent pageThe same can be applied to posts. For example, parent.posts would get all sibling posts.
