HTML forms with the form element

A form groups controls so a user can enter data and submit it to a destination.

Minimal example

<form action="/signup" method="post"> <label for="email">Email</label> <input id="email" name="email" type="email"> <button type="submit">Send</button> </form>

The label identifies the input, and the form sends its named values when submitted.

Common mistakes

• Give every control a label and a name.
• Choose the method that matches how the server should receive data.
• Do not rely on client-side validation alone for sensitive data.
