--- title: Content reuse tags: single-sourcing audience: writer, designer keywords: last_updated: summary: --- {% include linkrefs.html %} You can embed content from one file inside another using includes. Put the file containing content you want to reuse (e.g., mypage.html) inside the \_includes folder, and then use a tag like this: {% raw %} ``` {% include mypage.html %} ``` {% endraw %} With content in your \_includes folder, you don't add any frontmatter to these pages because they will be included on other pages already containing frontmatter. Also, when you include a file, all of the file's contents get included. You can't specify that you only want a specific part of the file included. However, you can use parameters with includes. See Jekyll's documentation for more information on that. ## Page-level variables You can also create custom variables in your frontmatter like this: ``` --- title: Page-level variables permalink: /page_level_variables/ thing1: Joe thing2: Dave --- ``` You can then access the values in those custom variables using the `page` namespace, like this: {% raw %} ``` thing1: {{page.thing1}} thing2: {{page.thing2}} ``` {% endraw %} Honestly, I haven't found a tremendous use case for page-level variables, but it's nice to know they're available. I use includes all the time. Most of the includes in the \_includes directory are pulled into the theme layouts. For those includes that change, I put them inside custom and then inside a specific project folder.
