Diff Component

A visual diff component built with semantic HTML and Tailwind CSS for comparing two content versions side by side. Perfect for code reviews, document revisions, and before/after comparisons. Supports horizontal, vertical, and resizable layouts with color-coded change tracking.

Diff components display differences between two versions of content, ideal for showing code changes, document revisions, or comparison views. Built with semantic HTML and color-coded styling, diffs help users understand what changed. The Frutjam diff system supports multiple types and styles—perfect for version control interfaces, revision history, and change tracking.
