How should a developer design for mobile screens?

A mobile design is not a smaller version of a desktop design. Each screen size needs its own specific layout plan. A developer must decide how elements change for different screen sizes.

The rule

A mobile design is not a smaller version of a desktop design.

Each screen size needs its own specific layout plan. A developer must decide how elements change for different screen sizes.

A developer must plan mobile layouts separately from desktop layouts. Decide which controls collapse or hide. Choose which items move into a menu. Ensure touch areas are large enough for fingers. Do not let the system automatically shrink a desktop view. This can cause many problems for the user.

A developer creates a website. The desktop version has a wide menu bar with many buttons. When viewed on a phone, these buttons wrap onto multiple lines. Some buttons are too big for the small screen. The developer should have designed a separate mobile menu, like a hamburger icon, to hold these buttons.

Questions people ask

More from the same record, pulled by shared topic — not written new for this page.

How can a developer ensure a user interface is not empty or sparse?

A developer must fill the screen with content. Large empty spaces at the top or bottom of pages are bad.

How should buttons be sized and arranged on a screen?

Buttons should only be as wide as the text they contain. Do not make buttons stretch to fill a space.

How many words should be in a text panel?

A text panel must have fewer than 60 words. Or, a text panel must have more than 95 words.

How many words should a content panel contain?

A content panel should be very short or long. It should not be a medium length.
