Orderly Network: SDK Theming
Customize the look and feel of your DEX using CSS variables, the theme provider, and component overrides.
When to Use
- Rebranding your DEX
- Changing color schemes
- Adding custom fonts
- Styling TradingView charts
- Creating PnL share cards
Prerequisites
- Orderly SDK packages installed
- Tailwind CSS configured
- Basic CSS knowledge
Overview
Orderly UI uses a CSS variable-based theming system with Tailwind CSS integration:
- CSS Variables - Define colors, spacing, border radius
- Tailwind Preset - Orderly's custom Tailwind configuration
- OrderlyThemeProvider - Component-level overrides
- Assets - Logo, favicon, PnL backgrounds
1. CSS Variables
All UI components use CSS variables prefixed with --oui-. Override them in your CSS to customize the theme.

}Best Practices
- Use RGB values - CSS variables use space-separated RGB (e.g.,
99 102 241) - Import order matters - Import Orderly styles first, then your overrides
- Test all states - Verify hover, active, disabled states look correct
- Check accessibility - Ensure sufficient color contrast (WCAG 2.1)
- Test on mobile - Some components have different mobile styling
- Match TradingView - Keep chart colors consistent with your theme
