Mobile/App and Responsive Design Guidelines
Forms and Input Fields Forms and input fields are commonly used for capturing user input using on-screen keyboards. Follow the guidelines below when using form elements:
- Use placeholder text for input fields where necessary. Apply left justification to the placeholder text.
- Use sufficient contrasting colors to distinguish the foreground text color from the background color.
- Include an action element to complete processing the form information if applicable.
Gestures Gestures—such as tap, drag, and pinch—are commonly used to interact with apps in place of mouse and keyboard actions. People generally expect gestures to work the same in all the apps they use.
