Pages and blogs
In Confluence, you create with pages and blog posts. Just like other documents you've used, you can fill pages and blog posts with text and tables, and format them to look pretty, funny, or professional. Confluence also lets you use macros and embed files so that you can have dynamic content in your documents, like videos, Jira issues, roadmaps, and automated reports.
How do pages and blog posts relate to spaces? If you think of spaces as separate folders or workspaces that you use to organise your work, pages and blog posts are the individual items that you use to fill up those folders.
Pages live in a page tree, where they can be nested and organised hierarchically, so you can have pages under pages (under pages). This lets you give your content structure and highlight relationships between pages, such as when you have a parent page about cats, and then child pages under that about different breeds of cats.
To create content faster, try using page templates. These are pre-formatted and feature relevant macros and instructions to help you create retros, meeting minutes, how-to-articles, decisions, and more. You can edit any of these templates to suit your own needs, or you can create your own templates from scratch.
Blog posts, on the other hand, display in an infinite scroll, where they're ordered chronologically. This means that they have a sense of timeliness and are more suited to announcements, news, and updates.
Every Confluence space, including your personal space, allows you to create pages in it, and has its own blog in which you can create posts.
