HTML Form Elements

HTML form elements are essential for creating interactive and user-friendly web applications. They allow users to input and submit data, making them a cornerstone of dynamic web development. At The Coding College, we aim to simplify your understanding of these elements and how they enhance form functionality.

What Are HTML Form Elements?

HTML form elements are building blocks used within a <form> tag to collect user input. These elements include text fields, buttons, checkboxes, radio buttons, dropdown menus, and more.

Basic Form Structure

<form action="/submit" method="POST">
  <!-- Form elements go here -->
</form>

Common HTML Form Elements

The <input> element is versatile and supports different types of user input.

Example: Text Input

<label for="name">Name:</label>
<input type="text" id="name" name="name">

Common Input Types

<textarea id="message" name="message" rows="4" cols="50"></textarea>

3. <select> and <option> Elements
