Customization of design and user interface
Introduction
Each operator wants a unique look for their casino, while maintaining the basic logic of the platform. UI design customization is based on theme engines, CSS variables, component systems and visual editors, minimizing code edits and ensuring consistency.
1. Engine Theme and CSS Variables
CSS Custom Properties
```css
: root {
--brand-primary: 1a73e8;
--brand-accent: fbbc05;
--font-family: 'Inter', sans-serif;
}
```
- in components are used via 'color: var (--brand-primary)'.
Dynamic loading of themes
Loading JSON config with palette and fonts in runtime.
Changing the attribute'data-theme = "brandA"' to '' → an automatic update of all styles.
2. Component libraries and design systems
UI libraries (Shadcn/ui, Ant Design, Material-UI)
Ready-made game cards, buttons, modals, tables, inputs.
Ability to override theme tokens through config.
Creating your own design system
Atomic Design: atoms (buttons, colors), molecules (game cards), organizations (lobby).
Storybook for visual documentation and testing.
3. Low-code and WYSIWYG editors
Theme Editor
Drag-and-drop change of logo, background images and color schemes without deploy.
Layout Builder
Drag and drop blocks (banners, tournament tape) to quickly assemble landing pages and promotions.
CMS integration
Visual configuration of promo banners and text blocks through the admin panel.
4. Adaptability and PWA
Mobile-first
Flexbox/Grid, media queries for breakpoints (320, 480, 768, 1024, 1440 px).
PWA functions
The colors of the theme in the manifest, icons, light/dark mode are synchronized with the OS settings.
Dark mode
Additional set of CSS variables ('--brand-primary-dark'), switching via 'prefers-color-scheme' or UI button.
5. Performance and optimization
Code-splitting и lazy-loading
Dividing bundles into core-UI and theme-assets, loading a theme on demand.
Caching
CSS files and JSON theme configs are cached with versioned URLs.
Critical CSS
Embed main UI styles in '' for quick above-the-fold rendering.
6. Multi-brand and white-label
Tenant-aware UI
Each tenant has its own themeId, which is used for authentication.
Runtime overrides
Entered in'localStorage 'or through the URL parameter'? theme = brandX '.
CI/CD
Automatic static assembly for each brand and depla in CDN.
Conclusion
Competent customization of UI on the online casino platform is based on theme engines, CSS variables, design systems and visual editors, providing flexibility, consistency and speed of launching new brands without deep code edits.
