HTML forms are used to collect data from users on a web page. They allow users to input information such as text, numbers, and files, and then send that information to a server for processing.
An HTML form is created using the <form> element, and contains a variety of different form controls such as text fields, checkboxes, radio buttons, select lists, and more. These form controls are used to create the different fields in the form that the user will interact with.
Here is an example of a simple HTML form that contains a text field, a radio button, and a submit button:
<form> <label for="name">Name:</label> <input type="text" id="name" name="name"> <br> <label for="gender">Gender:</label> <input type="radio" id="male" name="gender" value="male"> <label for="male">Male</label> <input type="radio" id="female" name="gender" value="female"> <label for="female">Female</label> <br> <input type="submit" value="Submit"> </form>
When the user fills out the form and clicks the submit button, the form data is sent to a specified server-side script for processing, usually via HTTP protocol, specially HTTP post method.
It's important to mention that forms can also be styled and customized using CSS, and can be enhanced using JavaScript.
