Case Zero

Case Zero is a dark-themed detective investigation dashboard built with plain HTML, CSS, and vanilla JavaScript. The app presents a fictional missing-artwork investigation with a top navigation, case overview, suspect details, evidence archive, timeline reconstruction, and accusation workflow.

Overview

This project is designed as a polished bug-hunt challenge app where contributors investigate a fictional case board, browse files, search evidence, and identify the culprit in a realistic detective UI.

Features

• Top navigation with Overview, Cases, Suspects, Evidence, and Timeline
• Investigation overview dashboard
• Search and filtering for case files
• Suspect profiles with personal alibi and evidence references
• Evidence archive with review status
• Chronological reconstruction timeline
• Case detail and accusation flow
• Local browser persistence for notes and review state

Run the app

For the simplest setup, open the project in a browser directly:

If you want to serve it locally instead, run:
