BlackHacker is a custom-designed theme for personal blogs and content-focused websites, built on a popular open-source CMS. It is intended for individual creators who want a distinctive, atmospheric design for their site. The theme features a dark, science-fiction inspired aesthetic that provides a focused reading environment.

• Page Expand Feature: The core visual element is an interactive 'page expand' function. The main content area initially appears condensed; clicking a designated button triggers a full-screen animation to reveal the complete post and sidebar.
• Integrated Audio Player: The theme includes integration for the MetingJS audio player, allowing for direct embedding and control of music or podcast episodes within posts or site pages.
• Custom Plugin Styling: It comes with pre-configured style support for several common user management and navigation plugins, such as ProfilePress and Page Navi, ensuring visual consistency.
• Optional Social Media Display: The code includes optional functionality for displaying a feed from a major Chinese microblogging platform, though this requires separate API key configuration by the user.
• Technical Requirements: The theme requires PHP version 7.0 or higher to function correctly, and users should be comfortable with basic file editing to configure optional features or remove unused elements.
