What does the Method Attribute define in a form tag?

The Method Attribute in a form tag is crucial as it defines how data is transmitted from the client to the server when the form is submitted. There are primarily two types of methods specified: GET and POST.

When the GET method is used, the form data is appended to the URL in the form of a query string. This method is suitable for searching or retrieving data, as it makes the data visible in the URL and is limited in size. Conversely, the POST method sends the data in the body of the HTTP request, making it more suitable for actions that change data on the server, such as submitting information or uploading files. Using the correct method ensures that data is sent in the appropriate format and manner according to the needs of the web application.

Understanding this differentiates it from other attributes that might concern user interface elements, the specific destination of the form action, or stylistic choices for the form, which do not pertain to how data is transmitted.
