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> tag, and it acts as a container for various form elements like text fields, buttons, checkboxes, radio buttons, and more.

Key Uses of HTML Forms

  3. Online Purchases:
    • Allows users to input their shipping details, payment information, and other necessary data for e-commerce transactions.
  4. Search Functionality:

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.
