What makes it different

Dark full-bleed header, hero and footer with a grid texture and soft glow. Command-palette style search with a "/" key hint. Bento grid of topics with a featured first card. Terminal-arrow popular articles list. Dark code blocks and mono labels in articles.

Included

Fully responsive, verified without horizontal overflow at 390px on home, category, section, article and search pages.

All Help Center templates are included: home, category, section, article, search, requests, new request, community, profile, service catalog and approvals. Colours, logo and favicon are editable in the Theming Center. Fonts are self-hosted (no Google Fonts request). Translated for English, Portuguese and Spanish; other locales fall back to English.
