Captions
Keep them near the item
Each caption should say what the reader is looking at, where it came from, and why it is useful in the archive.
Colophon
How the site is assembled, credited, and kept in order.
This page records the practical details behind the pages, files, and credit lines.
File groups
HTML pages, styles, images, and support files sit together as one site set.
The archive uses ordinary web files, a shared stylesheet, and a set of curated image records. That keeps the pages consistent while leaving room for new entries to be added in the same pattern.
The file names are short on purpose. They make the source list easier to read and the page links easier to follow.
Image handling
Display size is controlled by the page, not by the source file name.
Images are shown at the size the layout asks for, while the stored file stays detailed enough for clean display.
| Item | Practice | Reason |
|---|---|---|
| Hero images | Used as wide banners with a fixed frame | They set the page tone without breaking the layout. |
| Grid images | Scaled to fit their card or frame | They stay readable on smaller screens. |
| Source files | Kept at a useful working size | The site can show detail without stretching the image. |
| Video clips | When used, they get a clear credit line and a short note | Readers should know where the clip came from and why it is here. |
Text style
Short captions, direct credit, and ordinary nouns.
The colophon keeps the writing practical and easy to scan.
Credits
Put the collection name in plain view
The credit line belongs with the record itself so the reader does not have to hunt for it later.
Updates
Write change notes in small steps
A short note about what changed is enough when the page family already carries the structure.
Update rhythm
A steady archive grows one record at a time.
Small additions keep the set coherent and easy to review.
When a new page is added, the caption, the credit line, and the source link should all be ready together. That prevents loose records from drifting away from the collection page.
When an existing page is revised, the change should improve clarity rather than pile on detail. The archive reads better when every edit has a clear purpose.
Media inventory
The main file groups and the pages where they matter most.
This list keeps the colophon practical: files, roles, and where a reader will meet them.
