The Device in Their Hand

Someone opens a greeting card in a moment of privacy — standing in a parking lot, sitting in a waiting room, during a quiet afternoon. The device in their hand might be a phone. It might be a tablet they grabbed on the way out. It's almost never the screen where the sender carefully composed the message.

That gap between authoring and opening is the real design constraint. A layout that assumes the screen where the card was made will fall apart the moment it arrives elsewhere. Text that fit perfectly in the margin now collides with a photo's edge. An image that breathed in 16:9 becomes cramped in 9:16.

Flexible design — mobile-first, responsive, adapting to the actual screen in use — isn't about making something look "good" on every size. It's about protecting the emotional intention of the message, whatever screen it lands on. It's about honoring the private moment where it's actually being received.

Because your message deserves to arrive intact.
