Best Practices​

Content Guidelines​

  • Title: Keep titles concise and impactful (5-8 words typically work best)
  • Description: Limit descriptions to 1-2 sentences for optimal readability
  • Contrast: Ensure text remains readable against your background image

Image Selection​

  • Quality: Use high-resolution images (at least 1920px wide for full-width jumbotrons)
  • Subject: Choose images that don't compete with text for attention
  • Format: Optimize images for web (use appropriate compression)
  • Fallback: Consider how the component looks without an image during loading

Responsive Design​

  • Height: Use relative units (vh, %) for better mobile responsiveness
  • Width: Consider how your jumbotron adapts to different screen sizes
  • Text: Ensure text remains readable on mobile devices

Performance Considerations​

  • Image Size: Optimize background images to balance quality and load time
  • Loading: Consider lazy loading for jumbotrons below the fold
  • Caching: Utilize proper caching strategies for background images

Integration Tips​

Variable Binding​

  • Connect the jumbotron to data models when content needs to be dynamic
  • Use the Variable/Model field to bind to data sources
  • Access dynamic content through the model system

Conditional Display​

  • Use validation rules to show/hide jumbotrons based on user roles
  • Implement screen-specific visibility for different device types
  • Create dynamic content based on user preferences or application state

Accessibility​

  • Ensure sufficient color contrast between text and background
  • Provide alternative text context through proper heading structure
  • Consider users with motion sensitivity when using animated backgrounds
