Forms and User Input

Manual: General · Subject: Web Design & Development

Build forms that collect information and improve usability with labels and validation.

Why Forms Matter

Forms as a bridge

Forms let users send information to a website, such as contact details, search terms, checkout information, or feedback.

Accessibility and clarity

Every form field should have a clear label. Helpful placeholder text is fine, but it should not replace labels.

Common form elements

ElementPurpose
formWraps input controls
labelDescribes a field
inputAccepts user text or other data
textareaMulti-line text entry
buttonSubmits or triggers an action
⚠️

Do not hide important instructions

If users need a format such as a date, password rule, or phone number, make the requirement visible before submission.

Validation

Validation checks whether input is complete or correctly formatted. Some validation can happen in the browser, and some can happen on the server.
