Custom CSS: Add CSS directly inside the Section Block using this Block Setting. Click on the Edit in Modal button above the Selector to view the CSS in a larger popup modal. Use the Selector rule to change the Section Block Styles when using Custom CSS.
For example:
selector {
color: #ffff;
}
color: #ffff;
}
Third Method:

What is CSS Border Radius?
CSS Border Radius is a fundamental web design property that creates rounded corners on HTML elements, transforming sharp rectangular edges into smooth, curved shapes. The border-radius CSS property is essential for modern web design, enabling designers to create everything from subtle rounded corners to perfect circles and complex organic shapes. This versatile property has revolutionized web aesthetics, moving away from rigid rectangular layouts toward more natural, user-friendly interfaces.
How Does CSS Border Radius Work?
The border-radius property offers flexible syntax options for different design needs:
- Single value: Creates uniform rounded corners on all four corners
- Two values: Horizontal and vertical radius for elliptical corners
- Four values: Individual control for each corner (top-left, top-right, bottom-right, bottom-left)
- Eight values: Complete control over horizontal and vertical radius for each corner
- Percentage values: Responsive rounded corners that scale with element size
This flexibility allows for precise control over corner curvature, enabling both simple rounded rectangles and complex asymmetrical shapes.
Benefits of Rounded Corners
CSS border radius offers significant advantages for web design:
- Modern aesthetics: Creates contemporary, polished visual appearance
- Improved user experience: Softer edges feel more approachable and friendly
- Visual hierarchy: Helps distinguish different content sections
- Brand consistency: Maintains design language across interface elements
- Cross-platform compatibility: Works seamlessly across all devices and browsers
- Performance optimization: Pure CSS solution without image dependencies
Essential Border Radius Techniques
Master these core border radius approaches:
- Uniform radius: Equal curves on all corners for consistent appearance
- Asymmetric corners: Different radius values for unique visual effects
- Pill shapes: Maximum radius for button and badge designs
- Circular elements: 50% radius for perfect circles and avatars
- Organic shapes: Complex radius combinations for natural-looking elements
Popular Border Radius Applications
Rounded corners are particularly effective for:
- Buttons and interactive elements
- Cards and content containers
- Images and profile avatars
- Form inputs and text fields
- Navigation elements and tabs
- Modal windows and popups
- Progress bars and indicators
- Badge and label components
Design Best Practices
To create effective border radius effects:
- Use consistent radius values throughout your design system
- Consider element size when choosing radius values
- Apply subtle radius (2-8px) for small elements
- Use larger radius (12-24px) for cards and containers
- Maintain proportion between element size and corner radius
- Test responsiveness across different screen sizes
- Ensure accessibility with proper contrast and focus states
Creative Border Radius Ideas
Explore these popular rounded corner effects:
- Subtle corners: 4-8px radius for modern, clean appearance
- Soft cards: 12-16px radius for friendly, approachable containers
- Pill buttons: Maximum radius for modern CTA elements
- Organic shapes: Asymmetric radius for natural, flowing designs
- Responsive circles: Percentage-based radius for scalable circular elements
- Complex curves: Eight-value syntax for unique, artistic shapes
Advanced Border Radius Techniques
Take your designs further with advanced techniques:
- Responsive radius: Using viewport units (vw, vh) for scalable corners
- CSS custom properties: Creating reusable radius variables
- Animation effects: Smooth transitions between different radius values
- Pseudo-element combinations: Complex shapes using multiple elements
- Clipping paths: Combining border-radius with clip-path for advanced shapes
Browser Support and Performance
The border-radius property enjoys universal browser support, making it one of the most reliable CSS properties for modern web design. It’s hardware-accelerated on most devices, ensuring smooth performance even with complex radius combinations and animations.
CSS Border Radius generators streamline the design process, allowing designers to experiment with different corner configurations and instantly visualize results. This technology makes advanced shape creation accessible to designers of all experience levels, promoting creative exploration and efficient workflow optimization.
