HTML Forms
HTML Forms are an essential feature of web development used to collect and process user input on a website. They provide a structured way for users to interact with web applications, enabling them to submit data, make selections, or perform actions. This data is then sent to a server for processing. The form itself is defined using the <form>

How HTML Forms Work
Data Entry: Users enter their information into the form fields (like text boxes, dropdowns, etc.).
Form Submission: The form is submitted using a button, typically a “Submit” button, which triggers the form to send the data to a server.
Data Processing: The server processes the submitted data, such as saving it to a database, sending a confirmation email, or displaying a response to the user.
