Fragment "container": add 'gap' configuration and responsive behaviour

[Priyank_Gajera]

1. Gap Configuration Alternative

• Current Limitation: Direct configuration for a gap property is not available.

• Alternative Solution: Use the “Advanced tabs” feature.

• Implementation: Apply the Clay utility class c-gap-2 (or any c-gap-* variation) via the cssClasses field.

• Benefit: Leveraging c-gap-* classes avoids the need to write custom CSS.

2. Breakpoint-Specific Styling

• Ability to Change Behavior: You can already modify properties like text color and margins for an element based on the viewing breakpoint (e.g., desktop, tablet, mobile).
