4 = Submitting the Form: When a user clicks a submit button within a form, the form data is typically sent to a server-side script for processing. The server-side script can be written in languages like PHP, Python, or JavaScript, which receive the form data and perform actions based on the input.
5 = Form Validation: HTML forms can be validated to ensure that the entered data meets specific requirements. Validation can be done using HTML5 attributes like required
, pattern
, and min/max
attributes, or through JavaScript validation functions.
