Guidance

When to use

  • If you can’t reasonably predict a user’s answer to a prompt and there might be wide variability in users’ answers.
  • When using another type of input will make answering more difficult. For example, birthdays and other known dates are easier to type in than they are to select from a calendar picker.
  • When users want to paste in a response.

When to consider alternatives

Usage

  • Don't use placeholder text in form fields. Use hint text instead, if you need to provide contextual information. Placeholder text disappears after a user types a value, therefore users will no longer have that text available when they need to review their entries. People who have cognitive or visual disabilities have additional problems with placeholder text.
  • The length of the text field provides a hint to users as to how much text to write. Do not require users to write paragraphs of text into a single-line input box; use a textarea instead.
  • Text fields are among the easiest type of input for desktop users but are more difficult for mobile users.
  • Only show error messages or styling after a user has interacted with a particular field.

View the "Forms" guidelines for additional guidance and best practices.

Accessibility

  • Group each set of thematically related controls in a fieldset element. Use the legend element to offer a label within each fieldset. The fieldset and legend elements make it easier for screen reader users to navigate the form.
  • Keep your form blocks in a vertical pattern. This approach is ideal, from an accessibility standpoint, because of limited vision that makes it hard to scan from left to right.
