Hi,

You can theme Smart Kanban in a web project by overriding its built-in CSS variables and styles, without modifying the library’s core files.

Smart UI components, including Kanban, are built with CSS custom properties (variables), which makes theming straightforward.

For example:

--smart-primary: #3f51b5;
--smart-background: #ffffff;
--smart-surface: #f5f5f5;
--smart-border-color: #ddd;
--smart-border-radius: 4px;
--smart-font-size: 14px;
--smart-kanban-column-header-background: #f0f0f0;
--smart-kanban-task-background: #fff;

Best regards,
Markov
