Inputs enable a user to enter or edit data to influence or change their experience.
- Field: The area or box that holds the input.
- Label: The text above the field that describes the information needed.
- Placeholder (optional): The pre-populated, gray text in the field that hints at the format of the information required.
- Help message (optional): The text below the field that helps a user understand the input and successfully enter a correct value.

Design guidelines
Always include a label
- Placeholder text is not a replacement for labels .
- Place the label above the container.
- Choose short, descriptive words.
- Use sentence case without punctuation.
- Keep length to one line.
- Refer to Foundational Page for more details.
Use the label to indicate optional inputs
- Use “(optional)” to indicate if the input is optional.
- Required inputs do not need extra labels or copy.
Adjust the size of the field to the expected amount of input
- Field size should set expectations to how much input is required.
- Inputs for shorter values, like a phone number, should be smaller, and inputs for longer values, like a message, should be larger.
Help message, placeholder, and tooltip
The help message, placeholder, and tooltips help the user understand the input and any additional context.
Purpose | Limitation | |
|---|---|---|
| Help message | Information to clarify the label, always available in the default state. | Limit the help message to one line. |
| Placeholder | Hints at the format of the input; not crucial information. | Limited length depending on the width of the field; disappears when the user begins typing. |
| Tooltip | Elaborates on non-essential but helpful information about the input. The user should be able to understand the input field without the tooltip. | Users might not look at the contents of the tooltip. |
Field validation
Show error when the input is no longer in focus. Use animated transition delay of .4 milliseconds.
Swap help message with an error message when validation fails
