Mod FAQ

Is Mod a JavaScript library or a CSS framework?

Mod is primarily a CSS framework with accompanying HTML/component structures. It is designed to provide the styling and building blocks for your UI. Its framework-agnostic nature means it delivers styles and markup patterns that you can integrate using the JavaScript framework of your choice (like React or Vue) or use with plain HTML, making it incredibly versatile.

How does Mod handle customization and branding?

While Mod provides a complete, opinionated design system, it is built with customization in mind. The core CSS utilizes modern techniques like CSS custom properties (variables) for colors, spacing, and typography, allowing you to easily override and tailor the theme to match your specific brand identity. You can start with the polished defaults and adapt them as needed.

What does "framework-agnostic" actually mean for integration?

It means Mod does not require you to install a specific React or Vue plugin. Instead, you get clean, semantic HTML structures and CSS classes. You can copy the provided HTML snippets directly into your Svelte components, JSX in Next.js, or templates in Rails ERB files. The CSS you import handles all the styling, making it compatible with virtually any web technology that can output HTML.

Are updates and new components included?

Yes. Mod is committed to continuous evolution alongside web standards. A purchase includes access to yearly systemic updates, which encompass not only maintenance and bug fixes but also new components, style variants, and enhancements to the existing system. This ensures your UI toolkit remains modern and competitive without requiring a new purchase every cycle.
