Web forms are fundamental components of web development, facilitating user data input and submission through web pages. They encompass various input fields like text fields, checkboxes, radio buttons, and dropdown lists, serving diverse purposes such as contact forms, registration forms, surveys, etc.

A web form is a medium that allows your visitors to get in contact with you and to send information, such as an order, a query, etc. which is passed on to your database. The smallest error in the web form execution can lead to a huge loss of data or communication
