Lesson 5 - HTML Forms for Beginners: How to Collect User Input Like a Pro

👋 Introduction

If you’ve followed the last lessons, you now know how to build static content using HTML. But what if you want to let users interact with your site—like sending a message, filling out a survey, or logging in?

That’s where HTML forms come in. Forms are essential for collecting data from users and are used everywhere—from search bars to payment gateways.

🧱 Basic Form Structure

Here’s what a minimal form looks like in HTML:

<form action="/submit" method="POST">

<label for="username">Username:</label>

<input type="text" id="username" name="username">

<input type="submit" value="Submit">

</form>

Explanation:

• <form>: Wraps all form elements.
  
  

• action: Defines where the form sends its data.
  
  

• method: GET (for reading data) or POST (for sending data).
  
  

• <label>: Improves usability and accessibility.
  
  

• <input>: The actual field where users type.
  
  

🧰 Common Form Elements and How to Use Them

🔤 Text Input

<input type="text" name="fullname" placeholder="Enter your full name">

📧 Email Input

<input type="email" name="email" required>

🔒 Password Input

<input type="password" name="password">

☑️ Checkbox

<label><input type="checkbox" name="subscribe"> Subscribe to newsletter</label>

🔘 Radio Button

<label><input type="radio" name="gender" value="male"> Male</label>

<label><input type="radio" name="gender" value="female"> Female</label>

🔽 Select Dropdown

<select name="country">

<option value="us">United States</option>

<option value="br">Brazil</option>

</select>

📝 Textarea (Multiline Text)

<textarea name="message" rows="4" cols="40" placeholder="Type your message..."></textarea>

▶️ Submit Button

<input type="submit" value="Send">

You can also use:

<button type="submit">Send Message</button>

🔐 Understanding Form Attributes

action - URL to send the form data

method - HTTP method: GET or POST

name - Identifier for the form field (used on the backend)

placeholder - Guide text inside the input

required - Makes the field mandatory

disabled - Makes the field uneditable

value - Default value for the input

🧪 Example: Contact Form

<form action="/contact" method="POST">

<label for="name">Name:</label><br>

<input type="text" id="name" name="name" required><br>

<label for="email">Email:</label><br>

<input type="email" id="email" name="email" required><br>

<label for="message">Message:</label><br>

<textarea id="message" name="message" rows="4"></textarea><br>

<button type="submit">Send</button>

</form>

💡 Best Practices

• Always include <label> elements linked to inputs using for and id.
  
  

• Use required to ensure essential data is collected.
  
  

• Validate on both the client side (HTML/JS) and server side (Python, PHP, etc).
  
  

• Keep forms accessible (use semantic elements and consider screen readers).
