The HTML <form> Tag is used to create an HTML form. A form is a crucial part of web development that allows users to input data, which can then be sent to a server for processing.

The <form> Tag serves the following purposes:

• Input Collection: It provides a container to collect user input, such as text, checkboxes, radio buttons, and more.
• User Interaction: Forms facilitate interactive elements like buttons and drop-down menus, enhancing user engagement.
• Data Submission: When a user submits a form, the data entered into the form fields is sent to the server for further processing.
• Action and Method Attributes: The ‘action’ attribute specifies the URL where the form data should be submitted, and the ‘method’ attribute defines the HTTP method (e.g., GET or POST) used for the submission.

Syntax

<form action="/submit" method="POST">
    <!-- Form fields go here -->
    <label for="username">Username:</label>
    <input type="text" id="username" name="username">
    <label for="password">Password:</label>
    <input type="password" id="password" name="password">
    <input type="submit" value="Submit">
</form>

Note: In this example, the form is set to submit data to “/submit” using the POST method when the user clicks the “Submit” button. The actual form fields can vary depending on the information you want to collect.
