A free Bootstrap 5 template by Kontent (Ron Severdia): 24 Bootswatch themes, light, dark and auto colour modes, and a Cassiopeia compatibility mode for module positions. Joomla 4, 5 and 6.
Atomic is a free template by Ron Severdia (Kontent), written in its own code on Bootstrap 5 with no third-party template framework. It suits simple sites and serves as a base for custom builds.
Features
- Bootstrap 5 from Joomla core, a CDN, a custom URL, or any of 24 Bootswatch themes.
- Light, dark and auto colour-mode switcher that follows the OS preference.
- Cassiopeia compatibility option with mapped module positions for switching from Cassiopeia.
- One-, two- or three-column header, body and footer layouts; sticky header; off-canvas mobile menu.
- Google Fonts, Font Awesome (including FA 7 via CDN) and Bootstrap Icons, loaded without render blocking.
- Assets managed through the Web Asset Manager, with preconnect hints.
- OpenGraph, Twitter and Schema.org image meta tags, a GA4 ID field and four custom code injection points.
- Sample data plugin included in the package (System → Sample Data).
- 30 module positions and child template support.
- Joomla update server with an optional beta channel.
Installation
Install the package from the GitHub releases (template plus sample data plugin), not the repository archive: the repository also contains a folder with an older Atomic.
