Argon is a free, open-source Bootstrap 4 design system and UI kit from Creative Tim that ships with over 100 components and five pre-built HTML pages for landing pages, authentication screens, and marketing websites.

What is Argon?

Argon is a free, open-source Bootstrap 4 design system and UI kit created by Creative Tim, distributed through ThemeWagon. It provides a collection of ready-to-use HTML, CSS, and JavaScript components — buttons, forms, navigation, typography, alerts, and more — that developers can copy directly into their own projects. The kit outputs static HTML pages and runs on Bootstrap 4 with jQuery, FontAwesome icons, and SCSS source files for customization. It also includes example pages for landing, profile, login, and registration, so you can see how the components fit together in a real layout.

What makes Argon stand out?

Argon stands out for its breadth of components and its emphasis on production-ready, gradient-styled UI elements.

• Over 100 components — includes buttons with icons and multiple sizes, form controls, checkboxes, radios, toggle buttons, sliders, navigation pills, labels, alerts, tooltips, and popovers.
• Pre-built pages — ships with 5 HTML files covering landing, profile, login, and registration layouts, useful for seeing the kit in context.
• Bootstrap 4 integrated — built on Bootstrap v4.0.0 with jQuery v3.2.1, so it inherits the Bootstrap grid and utility classes.
• JavaScript components — includes interactive elements such as carousel sliders, a Bootstrap Datepicker, and noUiSlider for range sliders.
• SCSS source files — includes SCSS files so you can recompile and customize the design system to match your brand.
• Gradient effects and clean typography — uses gradient backgrounds, full-screen banners, and a typography system with heading, display, and paragraph styles.
• Icons and image avatars — uses FontAwesome icons and provides avatar variations (square, circle) for team sections and social media icons.
