What makes Mod different from other CSS frameworks like Tailwind or Bootstrap?

While frameworks like Tailwind provide low-level utility classes and Bootstrap offers generic components, Mod is specifically engineered for SaaS products. It provides high-level, complex components (like dashboards, settings panels, and data grids) with a cohesive aesthetic designed for business software. It’s more opinionated and complete out-of-the-box than Tailwind, and more modern and specialized than Bootstrap, offering a direct path to a professional SaaS UI without assembly required.

Is Mod compatible with my current React/Vue/Svelte project?

Absolutely. Mod is fundamentally CSS and HTML-based, making it completely agnostic to your JavaScript framework. You can use its CSS classes and copy its component HTML structures directly into your React components, Vue templates, or Svelte files. It does not require installing a specific React or Vue library, which avoids vendor lock-in and ensures compatibility with your existing build process and tooling.

How does the theming and dark mode support work?

Mod includes two fully realized themes: a light theme and a dark theme. Theming is controlled through CSS custom properties (variables). Applying the dark theme is as simple as adding a .mod-dark class to a parent element (like the <body> tag). All components, colors, and icons will automatically switch to their dark variant. This system is easy to implement and allows for user-controlled theme toggling with minimal JavaScript.
