Technical Specification: Free Online HTML Tag Stripper

Overview

A clean, efficient, single-file browser utility designed to transform messy HTML code into structured plain text. This tool serves developers, content managers, and students who need to extract readable content from raw source code or web scraps.

Core Features

• Live Processing: Instant conversion as the user types or pastes into the input field.
• Customizable Stripping: Toggleable options to include/exclude specific elements (e.g., <script>, <style>, <iframe>, <div>).
• Whitespace Optimization: Automatic detection and reduction of redundant whitespace and empty line breaks.
• Format Preservation: Optional setting to preserve line breaks (<br> and <p> tags) or convert them to standard newline characters.
• Utility Controls: 'Copy to Clipboard', 'Clear Input', and 'Copy Results' buttons with intuitive feedback animations.
• Statistics Module: Real-time character and word count tracking for both input and output.

UI/UX Design

• Layout: A dual-pane split view on desktop (Input on left, Output on right) that stacks vertically on mobile devices.
• Aesthetic:
  • Color Palette: Off-white background (#f9fafb), slate text (#1f2937), and a primary action color of vibrant blue (#2563eb).
  • Components: High-contrast, borderless text areas with subtle rounded corners and soft drop shadows on focus.
  • Transitions: Smooth fade-in animations for results and button interactions.
• Responsiveness: Fluid layout using CSS Flexbox/Grid to handle window resizing seamlessly.

Technical Directives & Constraints

• Architecture: Single HTML file containing CSS, HTML, and Vanilla JavaScript.
• State Management: Strictly NO LocalStorage/Cookies/IndexedDB. All state (input text, current configuration) must be handled in-memory.
• Browser Environment: Designed for sandboxed iframe compatibility.
• External Assets: CSS via Tailwind CSS (via CDN), Google Fonts (Inter font), and lightweight vector icons (e.g., Phosphor Icons).
• Performance: Use efficient Regex or DOMParser for stripping to ensure near-instant updates on large HTML pastes.
• Interactions: Use event listeners (input) for real-time reactivity. Replace standard browser alerts with custom, elegant toast notifications.

Implementation Steps

1. Setup: Create a single index.html structure with meta tags for responsive mobile design.
2. Styling: Inject Tailwind CSS and set global font to 'Inter'. Define CSS classes for the clean, light-mode look.
3. Logic:
   • Implement the stripper function using DOMParser. Input the HTML string into a temporary DOM node to sanitize it effectively without regex vulnerabilities.
   • Build the control panel as a side/top bar to toggle extraction options.
   • Implement the 'Copy' function using the Clipboard API.
4. Accessibility: Ensure all buttons have aria-label attributes and the contrast ratio meets WCAG 2.1 standards.
