#Understanding the Five Core Colors
Each widget theme is built around five essential colors that control different aspects of the appearance:
Primary Color
Purpose: Main action elements, highlights, and branding accents
Used for: Buttons, active states, important highlights, selection indicators
Example: #FF0000 (red) for call-to-action elements
Home Color
Purpose: Home team representation in sports widgets
Used for: Home team scores, names, and related elements
Example: #00003c (dark blue) for home team styling
Away Color
Purpose: Away/visiting team representation in sports widgets
Used for: Away team scores, names, and related elements
Example: #ff0000 (red) for away team styling
Background Color
Purpose: Main widget background and container areas

#Fine Tuning Your Theme
After downloading your theme, you can make detailed adjustments by editing the theme.css file. The theming system uses a specific CSS class naming convention to avoid conflicts with your website styles.
#CSS Class Naming Convention
Recommended: Use .srt- prefixed classes
These classes are designed for customization and are safe to modify:
/* Background colors */
.sr-bb .srt-base-1 {
background-color: #f5f5f5;
}
/* Text colors */
.sr-bb .srt-text-primary {
color: #333333;
}
/* Border styles */
.sr-bb .srt-border-1 {
border-color: #e0e0e0;
}If you need more fine grained control over styling, you can write your own styles, but we encourage you to only style classes with prefix, which are meant for branding. We offer no guarantee that any other classes or internal widget structure won't change in the future. You also need to use at least 2 class selectors for every rule (.sr-bb is always available on every widget), so they are not overridden with our css normalization rules.
#CSS Isolation Rules
Important for CSS Isolation
All widget styles are scoped within .sr-bb containers. For proper isolation:
- Don't use
sr-orsrt-prefixes in your site's CSS - Avoid bare element selectors like
div,span,pin global styles and using spacing properties likeradius|top|padding|marginmight cause issues with future updates to your setup. - Test thoroughly after theme changes to ensure no style conflicts
#Showcase
As mentioned earlier, we have predefined themes on our demo page. Here are two showcases, light and dark theme, for our Match preview widget.
