Radio input

Select only one

Remember, when working with forms, add the aria-describedby attribute, and some helpful text, to allow a seamless experience for everybody.

Keep your form on a white background to enable full contrast ratios for form validation messages.

While using input type="number" users could accidentally increase or decrease the number using the scroll wheel on the mouse or the scroll gesture on their trackpad. This feature can be useful when collecting countable data but bad if entering data such as passport numbers. We have switched to input type="text" inputmode="numeric" pattern="[0-9]*" because it allows for a degree of separation between how the user enters data (“input mode”), what the browser expects the user input to contain (type equals number), and potentially how it tries to validate it.

Use the radio component when the user must select only one option.
