What is an HTML Form

HTML Forms are required to collect different kinds of user inputs, such as contact details like name, email address, phone numbers, or details like credit card information, etc. Forms contain special elements called controls like inputbox, checkboxes, radio-buttons, submit buttons, etc. Users generally complete a form by modifying its controls e.g. entering text, selecting items, etc. and submitting this form to a web server for processing. The <form> tag is used to create an HTML form. Here's a simple example of a login form:

<form method="POST" action="some_action>
    <fieldset>
        <legend>Log In</legend>
        <label>Username: <input type="text"></label>
        <label>Password: <input type="password"></label>
        <input type="submit" value="Submit">
    </fieldset>
</form>
