Introduction to HTML Forms
HTML forms are used to collect user input on a website. They allow users to enter data that can be sent to a server for processing. Forms are a crucial part of web development as they enable interaction with the users. In HTML, forms are created using the <form> element and various input elements for gathering different types of data.
Structure of an HTML Form
An HTML form is defined using the <form> element. Within the form, different input elements such as text fields, checkboxes, radio buttons, and submit buttons can be added to gather specific types of information. Each input element is defined by its own HTML tag.

Common Input Types in HTML Forms
HTML forms support various input types such as text, password, radio buttons, checkboxes, select dropdowns, file uploads, and more. Each input type serves a different purpose and can be used depending on the data that needs to be collected.

Forms can be styled using CSS to improve their appearance and layout. Additionally, HTML5 introduced new attributes and form validation features that can be used to ensure the data entered by users meets specific criteria before submission.
