Terminal

Published on 2025-12-29 09:03:45

Terminal Style simulates the computer interfaces of the 1970s and early 80s—the pre-GUI era of DOS and Unix. In this world, the mouse didn't exist; everything depended on keyboard commands via a Command Line Interface (CLI). In pop culture, this aesthetic has become synonymous with Hackers, Geeks, and Cyberpunk (think the "Code Rain" in The Matrix). In modern web design, it is often used for cybersecurity, developer tools, or crypto projects to convey a sense of "hardcore," "low-level," and "absolute control." Visual Characteristics Monochrome Phosphor: To mimic vintage CRT (Cathode Ray Tube) monitors, the color palette is severely restricted. The background is Pitch Black, while the foreground features glowing Phosphor Green, Amber, or Signal White. Designs often include Glow, Scanlines, and Screen Flicker effects to enhance retro realism. Character-Based Aesthetics (ASCII): Typography is strictly Monospace. Images are not bitmaps but ASCII Art constructed from characters. Dividers are made of --- or ===, progress bars are [|||||...]—every design element is reduced to a glyph, emphasizing information over decoration. The Cursor & Interaction: The Blinking Block Cursor is the heartbeat of this style. Interactions often simulate a Typewriter Effect, where content is revealed character-by-character rather than loading instantly. This "slowness" adds a sense of realism and tension, simulating a live connection or task execution.

Style System

**Role:** You are a Senior Frontend Architect and Retro-Computing Enthusiast. You specialize in "Creative Coding" and have a deep understanding of browser rendering engines. You reject modern GUIs in favor of raw, text-based interfaces, simulating the experience of 1980s CRTs using modern, performant HTML5 and CSS3. **Task:** Develop a complete, single-file landing page for a Cybersecurity platform using the **Terminal / CLI / DOS** aesthetic. **[CONFIGURATION]** - **[STYLE_NAME]:** Terminal / CLI / DOS (Retro-Computing) - **[INDUSTRY]:** Cybersecurity & Ethical Hacking - **[PROJECT_NAME]:** ZERO_DAY - **[TECH_STACK]:** HTML5 + Modern CSS3 (No JavaScript frameworks. All visuals/animations must be pure CSS). - **[PAGE_STRUCTURE]:** 1. **Header:** System Status Bar (IP, Uptime, User: ROOT). 2. **Hero:** Command Line Interface with Typing Animation & ASCII Art Logo. 3. **Trust Bar:** "Authorized Protocols" (Partner Logos rendered as text/ASCII). 4. **Feature Grid:** "System Modules" (Directory listing style). 5. **Workflow:** "Execution Chain" (Step-by-step terminal logic). 6. **Metrics:** "System Diagnostics" (ASCII progress bars). 7. **Testimonials:** "Encrypted Transmission Logs". 8. **Pricing:** "Access Level Clearance". 9. **Footer:** Hex Dump & System Shutdown commands. **Technical Requirements:** 1. **Global Design Tokens (`:root`):** - **Phosphor Palette:** `--terminal-bg: #0d1117;` (Void Black), `--phosphor-main: #00ff00;` (Matrix Green) OR `--phosphor-amber: #ffb000;`. - **Typography:** `--font-stack: 'VT323', 'Courier Prime', monospace;`. Text must be uppercase where appropriate. - **CRT Effects:** `--glow-strength: 0 0 10px var(--phosphor-main);`, `--scanline-color: rgba(0,0,0,0.5);`. 2. **Advanced Visual Effects (Pure CSS):** - **CRT Scanlines:** Create a pointer-events-none overlay using a repeating linear gradient to simulate television scanlines. Add a subtle `@keyframes` flicker animation to the body opacity to mimic screen refresh rates. - **Text Glow:** Apply `text-shadow` to all text elements to simulate electron beam bleeding. - **Typing Animation:** In the Hero section, use CSS `steps()` and `overflow: hidden` to reveal text character by character, simulating a live keyboard input. - **Blinking Cursor:** Use a `::after` pseudo-element with `content: '█'` and a blink animation on active input fields or the hero tagline. - **Glitch Effect:** Apply a subtle CSS clip-path glitch animation on hover states for buttons/links. 3. **Layout Logic:** - **The "Table" Look:** Even though you are using CSS Grid/Flexbox, the layout should visually mimic old-school HTML tables or DOS GUI borders. - **ASCII Borders:** Use `border: 2px solid var(--phosphor-main)` or simulate ASCII borders (e.g., `+-----+`) using pseudo-elements for content boxes. - **Monospace Alignment:** Ensure content aligns perfectly to the character grid. 4. **Custom Scrollbar:** - **Target:** `::-webkit-scrollbar`. - **Style:** Brutalist and blocky. - **Track:** Dark background (`#000`). - **Thumb:** Solid block of the main phosphor color (`var(--phosphor-main)`). No border radius. 5. **Component Specifics:** - **Trust Bar:** Do not use image logos. Use text representations or simple CSS shapes to represent partner protocols. - **Metrics:** Create progress bars using nested divs or linear-gradients, looking like `[||||||||||.....] 75%`. - **Pricing:** Display as "License Keys" or "Permission Levels" (Read/Write/Execute).
