Quick Answer

Div-idy builds mobile-friendly layouts by default. To make mobile behavior intentional, include details in your prompt about mobile-first layout, touch-friendly controls, spacing, and performance. The clearer you are about mobile priorities, the better the result.

What Div-idy does automatically

  • Responsive layouts that adapt to screen size
  • Scalable text and images
  • Basic touch-friendly buttons and inputs
  • Mobile viewport configuration
Good to know

You don’t need to mention “responsive design” for it to work—but you can improve the outcome by being explicit.

How to prompt for intentional mobile design

  • Say “mobile-first”: Prioritize small screens before desktop
  • Ask for stacked layouts: Single-column layouts on phones
  • Specify touch targets: Large buttons and tap areas
  • Control spacing: Extra padding between interactive elements
  • Limit clutter: Hide or collapse non-essential content on mobile
  • Performance: Ask for lightweight animations and fast load
