A form is a part of a website that gathers information and sends it when someone is ready. It is like filling out a paper application: you answer questions, then hand it in. A web form may contain fields, choices, and a button to send the answers.
For example, a contact form might ask for a name, email address, and message. The page can check that required answers are present before it sends them.
Group related questions together and label each one clearly. Before sending, tell people what will happen to their information so they know why the form is asking for it.
