💡 Why This Matters

🌍 Real World

Forms are everywhere on the web for collecting user information like sign-ups, contact details, and surveys.

💼 Career

Knowing how to create accessible and correct input fields is essential for front-end web development jobs.

1

Create the HTML form skeleton

Write the opening <form> tag and the closing </form> tag to create a form container.

HTML

Hint

The form tag wraps all the input fields.

2

Add a text input for the user's name

Inside the <form>, add a <label> with the text Name: and an <input> with type="text" and id="name".

HTML

Hint

Use type="text" for the name input and link the label with for="name".

3

Add email and password inputs

Below the name input, add a <label> with text Email: and an <input> with type="email" and id="email". Then add a <label> with text Password: and an <input> with type="password" and id="password".

HTML

  Name:
  
  
  

Hint

Use type="email" for the email input and type="password" for the password input.

4

Add a number input for age

Below the password input, add a <label> with text Age: and an <input> with type="number" and id="age". Then close the form with a submit button: <button type="submit">Submit</button>.

HTML

  Name:
  
  Email:
  
  Password:
  
  
  

Hint

Use type="number" for the age input and add a submit button to send the form.

Practice

1. Which input type should you use to let users enter their email address?

easy

A. password

B. text

C. email

D. number

Solution

1. Step 1: Understand the purpose of input types

   The email input type is designed specifically to accept email addresses and validate their format.

2. Step 2: Match input type to data

   Since the question asks for an input type for email addresses, email is the correct choice.

3. Final Answer:

   email -> Option C

4. Quick Check:

   Email input type = email [OK]

Hint: Use email type for email inputs to get validation [OK]

Common Mistakes:

• Using text instead of email loses validation
• Choosing password hides input unnecessarily
• Using number for emails is invalid

2. Which of the following is the correct syntax for a password input field in HTML?

easy

A. <input type='password'>

B. <input password>

C. <input type='pass'>

D. <input type='text-password'>

Solution

1. Step 1: Recall correct input type attribute

   The correct attribute for password fields is type='password'.

2. Step 2: Check each option's syntax

   Only <input type='password'> uses the correct attribute and syntax for a password input.

3. Final Answer:

   <input type='password'> -> Option A

4. Quick Check:

   Password input syntax = <input type='password'> [OK]

Hint: Password inputs use type='password' exactly [OK]

Common Mistakes:

• Omitting type attribute
• Using incorrect type names like 'pass' or 'text-password'
• Writing without type

3. What will the browser do when a user enters letters into this input field?

<input type='number' id='age' name='age'>

medium

A. Accept letters and submit as is

B. Show an error and prevent form submission

C. Automatically convert letters to numbers

D. Ignore the input and submit empty

Solution

1. Step 1: Understand number input behavior

   The number input only accepts numeric values and shows an error if invalid input is entered.

2. Step 2: Predict browser validation

   If letters are typed, the browser will prevent form submission and show a validation error.

3. Final Answer:

   Show an error and prevent form submission -> Option B

4. Quick Check:

   Number input blocks letters = error shown [OK]

Hint: Number inputs block letters and show errors [OK]

Common Mistakes:

• Thinking letters are accepted silently
• Assuming automatic conversion to numbers
• Believing input is ignored without error

4. Identify the error in this HTML snippet:

<input type='email' name='user_email' placeholder='Enter email'>
<input type='number' name='age' min='0' max='100'>
<input type='password' name='pass'>
<input type='text' name='username' required='false'>

medium

A. The required attribute cannot have a value

B. The min and max attributes are invalid on number inputs

C. The placeholder attribute is not allowed on email inputs

D. The type attribute is missing on the password input

Solution

1. Step 1: Review the required attribute usage

   The required attribute is a boolean attribute and should not have a value like 'false'. It is either present or absent.

2. Step 2: Check other attributes

   min and max are valid for number inputs, placeholder is valid for email, and type='password' is present.

3. Final Answer:

   The required attribute cannot have a value -> Option A

4. Quick Check:

   Boolean attributes have no value = The required attribute cannot have a value [OK]

Hint: Boolean attributes like required have no value [OK]

Common Mistakes:

• Setting required='false' instead of removing attribute
• Thinking min/max are invalid on number inputs
• Confusing placeholder usage on email inputs

5. You want to create a form input that:
- Accepts only numbers between 1 and 10
- Shows a placeholder "Enter a number"
- Is required to submit the form
Which is the correct HTML code?

hard

A. <input type='text' min='1' max='10' placeholder='Enter a number' required>

B. <input type='number' placeholder='Enter a number'>

C. <input type='number' min='1' max='10' placeholder='Enter a number' required='false'>

D. <input type='number' min='1' max='10' placeholder='Enter a number' required>

Solution

1. Step 1: Choose input type for numbers

   Use type='number' to accept only numeric input.

2. Step 2: Set min, max, placeholder, and required correctly

   Set min='1' and max='10' to limit range, add placeholder text, and use required as a boolean attribute without value.

3. Step 3: Verify options

   <input type='number' min='1' max='10' placeholder='Enter a number' required> matches all requirements correctly. The version using type='text' allows non-numeric input, the one with required='false' misuses the required attribute, and the simplest version lacks range limits and the required attribute.

4. Final Answer:

   <input type='number' min='1' max='10' placeholder='Enter a number' required> -> Option D

5. Quick Check:

   Number input with min, max, placeholder, required = <input type='number' min='1' max='10' placeholder='Enter a number' required> [OK]

Hint: Use type='number' with min, max, and required (no value) [OK]

Common Mistakes:

• Using type='text' for numbers
• Setting required='false' instead of removing attribute
• Omitting min and max for number limits
