These are a couple of demo pages that I use for testing different web technologies. I use these to hack together a proof-of-concept so I can share or reference them later.
These pages are mostly interesting for me instead of codepens because I can host them, reference them alongside blog posts or other links, and I have full control over HTTP headers and styles. Currently, they test CSS features and structured data, but I may add more in future.
If you’re confused or found a problem, get in touch with me on Bluesky or email me at [contact]@[this domain].
