About this glossary
I’m building this glossary to become a better developer and website strategist, in my ongoing quest to build clearer, better websites. It maps how terms relate, adds practical examples, and highlights best practices so I can communicate more clearly with clients. If it helps others too, great.
It’s a living resource, I aim to cite sources clearly. If you spot errors or omissions, please contact me so I can update it. Drafts may be assisted by AI, I review and fact check before publishing. For details on how I use AI, see AI Use at Webmarks.
