Three Columns, a website format that shows its sources
A self-demonstrating publishing format that separates plain answers, previewed sources, and technical detail into three columns.
Field notes
The page organizes one subject into three reading depths: an introductory answer, a source card, and technical detail. Numbered references move readers to source cards that identify the source and explain its role before presenting the external link. The author also documents failure handling: a dead link is disabled rather than erased, with its destination and a dated notice retained. The implementation is presented as a single file with responsive buttons, dark mode, and PDF output.
