What is a .css file?
CSS (.css) is a plain-text stylesheet describing how HTML elements are presented — colors, layout, typography, and responsive behaviour. It uses selectors paired with declaration blocks, and modern CSS adds custom properties (variables), flexbox and grid layout, and media queries.
How to use this file
Use an example .css file to test syntax highlighters, CSS parsers and minifiers, linters (stylelint), and pipelines that process or bundle stylesheets.
How to use this file for testing
“PWA — app-shell.css SAMPLE” is a deterministic Novus Examples fixture for Web assets. Favicons, web app manifests, service workers, robots and sitemap files, Open Graph images, and .well-known resources — for testing web tooling, crawlers, PWA installers, and asset pipelines.
Documented properties for this file: pwa-shell. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Web-platform fixtures are standards-compliant samples against fictional example.com data. Test crawlers, PWA installers and manifest validators, favicon/icon pipelines, service-worker registration, or .well-known parsers against the documented structure.
