Breakpoints

Specification reference for Web breakpoints: widths, inheritance, overridable fields, and hide rules. Concepts: Layout System. Setup: Page & Component Basics.

Built-in Widths

BreakpointRangeNotes
Desktop1280px – 1920pxPrimary breakpoint — build structure here first
Tablet768px – 1279pxInherits Desktop unless overridden
Phone0px – 767pxInherits Desktop unless overridden

Inheritance and Overrides

RuleDescription
ScopeWeb client only
PrimaryDesktop (fixed)
InheritanceTablet and Phone inherit Desktop; Tablet and Phone do not inherit each other
Desktop editSyncs to Tablet/Phone until those breakpoints override a field
OverrideOnce edited on Tablet or Phone, that field stops following Desktop
ResetUse Reset on a field to inherit from the parent breakpoint again

Recommended workflow

  1. Complete layout on Desktop.
  2. Switch to Tablet — change only what differs.
  3. Switch to Phone — stack, scroll, hide.
  4. Re-check Desktop so phone-only tweaks were not applied there.

Overridable Design Fields

SectionExamples
PositionType, offsets, z-index
SizeWidth, height, min/max, margin, padding
LayoutDirection, alignment, gap, wrap, overflow
StyleVisibility, opacity, background, border, shadow
💡

Custom configuration, Data, and Action tabs are generally not split by breakpoint.

Hide at a Breakpoint

💡

To hide on one breakpoint only, use visibility — do not delete the component from the tree.

Hide at breakpoint

ActionResult
Delete on DesktopRemoved everywhere
Hide on PhoneStill in tree; hidden on Phone only
Hide on TabletAffects Tablet only

Relation to Native App

Native App is a separate client. It does not participate in Web breakpoint inheritance.
