Fix CSS linting errors across project stylesheets

[Copilot]

Ran stylelint with stylelint-config-standard across project CSS files, resolving all 114 errors.

static/css/labman.css

• Fixed typo: padding-rightL → padding-right
• Renamed #btn__nav → #btn-nav (kebab-case; updated templates/base.html)
• Fixed unitless margin: margin: -12 0 0 -12 → margin: -12px 0 0 -12px
• Fixed deprecated @media (min-width: Npx) → @media (width >= Npx) range notation
• Modernised colour: rgba(0,0,0,.85) → rgb(0 0 0 / 85%)
• Fixed keyword case: optimizeLegibility → optimizelegibility
• Reordered selectors and split combined footer rule to fix no-descending-specificity

apps/autocomplete/static/autocomplete/css/autocomplete.css

• Renamed all class selectors to kebab-case (e.g. phac_aspc_form_autocomplete → phac-aspc-form-autocomplete, hasFocus → has-focus)
• Replaced deprecated word-wrap with overflow-wrap and clip: rect(...) with clip-path: inset(50%)
• Modernised rgba() → rgb() with / alpha notation; #eeeeee → #eee
• Fixed shorthand redundancies, currentColor → currentcolor, bare zero units
• Reordered selectors to resolve no-descending-specificity violations

Companion updates

All files referencing renamed identifiers updated for consistency:

• templates/base.html — btn__nav → btn-nav
• 4 autocomplete templates + autocomplete.js — updated CSS class references
• ac_container.html renamed → ac-container.html

Tooling

• Added .stylelintrc.json (stylelint-config-standard)
• Added package.json with npm run lint:css script
• Added node_modules/ to .gitignore

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• labman.leeds.ac.uk
  • Triggering command: /usr/bin/python3 python3 manage.py check (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
