HTML Forms

HTML forms enable user interaction by collecting input data and submitting it to servers. Learn to create accessible, well-structured forms with proper validation and user experience patterns.

HTML forms are essential components for creating interactive websites that collect user input. They enable everything from simple contact forms to complex registration systems, search functionality, and e-commerce checkouts.

What are HTML Forms?

HTML forms are interactive elements that collect user input and submit data to web servers for processing. They consist of form controls like text fields, buttons, checkboxes, and dropdown menus enclosed within a form element.

📝 Common Form Uses

  • Contact Forms: Collect user messages and inquiries
  • Registration Forms: Create user accounts and profiles
  • Login Forms: Authenticate existing users
  • Search Forms: Allow users to search content
  • Survey Forms: Gather feedback and opinions
  • Checkout Forms: Process orders and payments

Basic Form Structure

Every HTML form begins with the <form> element, which acts as a container for form controls and defines how data will be submitted.
