Changelog

A display that orders events by time, using timestamps, markers and content to explain sequence. It works for activity logs, project journals or order history. Unlike a stepper, which emphasizes task stages to complete, a timeline tells an event story. Keep titles and times visible when details expand.

A vertical list of collapsible sections: clicking a header expands its content and clicking again collapses it, either exclusively (one open at a time) or independently. Packs grouped content into limited space for on-demand expansion.

A small status marker attached to an element's corner or inline: a dot, a count or a short label. It signals unread counts, status (new, deprecated) or category; non-interactive and visually subordinate to its host element.

Narrows a large list to whatever matches the current input: every keystroke filters the list in place, with hit counts and an empty-state hint. Finding becomes pruning — no submit, no page jump, feedback stays right in front of the user.

A long-lived, reading-first content page: a collapsible docs tree on one side, the article column carrying heading hierarchy, paragraphs, code blocks and callouts, and on wide screens a page TOC marking the current position. Permanent links and prev/next links chain pages into a site; search is the primary entry; the structure is stable enough to memorize.
