HTML Forms and Input Elements – A Beginner’s Guide

Forms are an essential part of any website, allowing users to enter and submit information. Whether it’s a login form, search bar, or contact form, HTML forms and input elements make user interaction possible.

In this guide, we’ll explore how to create HTML forms, different input types, and how to handle form data.

What is an HTML Form?

An HTML form collects user input and sends it to a server for processing. It is created using the <form> element.

Basic Form Structure

<form action="submit.php" method="post">
    <label for="name">Name:</label>
    <input type="text" id="name" name="name">
    <button type="submit">Submit</button>
</form>

📌 Explanation:
✔ <form> – Defines the form
✔ action="submit.php" – The URL where the form data will be sent
✔ method="post" – Defines how data is sent (GET or POST)
✔ <label> – Describes an input field
✔ <input type="text"> – A text field for user input
✔ <button type="submit"> – A submit button
