HTML Studio: Auto Fixer & Validator

About

Stop wasting time hunting for missing closing tags, broken CSS, or unclosed attributes. HTML Studio is a powerful "Mini-IDE" directly in your browser that detects, validates, and automatically repairs broken code with a single click.

Unlike simple find-and-replace tools, HTML Studio uses a smart "Stack-Based Parsing" algorithm. It understands the hierarchy of your code, fixing errors without breaking your layout logic.

🚀 KEY FEATURES:

✅ Smart HTML Auto-Close: Automatically closes unclosed tags (div, table, lists) while preserving the correct parent-child hierarchy.
✅ CSS Repair Module: Fixes missing semicolons, cleans up empty properties, and organizes inline styles automatically.
✅ Attribute Intelligence: Instantly fixes missing quotes on attributes while smart-ignoring boolean attributes (like 'checked' or 'disabled').
✅ Code Safety & Entities: Intelligently handles non-HTML content (like C++ generics `Vector<String>`) by converting them to HTML entities instead of breaking the DOM.
✅ Real-Time Diagnosis: See errors line-by-line with detailed "Expected vs. Found" reports.
✅ Instant Preview: Test your fixed code immediately in a secure, isolated new tab.
✅ Clean UI: Dark mode interface designed for developer focus.

Perfect for web scrapers, legacy code maintainers, students, and developers who want clean code fast.
