💼 Career

Knowing how to build accessible forms is essential for web developers and front-end engineers.

1

Create the form skeleton

Write the basic HTML form structure with a <form> element containing two input fields: one with id="name" and one with id="email". Do not add labels or placeholders yet.

HTML

Hint

Start by writing a <form> tag. Inside it, add two <input> tags with the exact id attributes name and email.

2

Add labels for inputs

Add a <label> for each input. The label for the name input should have for="name" and the text "Name:". The label for the email input should have for="email" and the text "Email:".

HTML

Hint

Use the <label> tag with the for attribute matching the input's id. Write the label text exactly as "Name:" and "Email:".

3

Add placeholder text inside inputs

Add a placeholder attribute to the name input with the value "Enter your full name" and to the email input with the value "Enter your email address".

HTML

  Name:
  
  Email:
  
  

Hint

Add the placeholder attribute inside each <input> tag with the exact text given.

4

Complete the form with a submit button

Add a <button> inside the form with type="submit" and the text "Send".

HTML

  Name:
  
  Email:
  
  

Hint

Add a <button> tag with type="submit" and the text "Send" inside the form.

Practice

1. What is the main purpose of a <label> element in an HTML form?

easy

A. To describe what the input field is for and improve accessibility

B. To provide example text inside the input field

C. To style the input field with colors

D. To submit the form data to the server

Solution

1. Step 1: Understand the role of <label>

   The <label> element connects text to an input field, helping users know what to enter.

2. Step 2: Recognize accessibility benefits

   Labels also help screen readers announce the input purpose, making forms accessible.

3. Final Answer:

   To describe what the input field is for and improve accessibility -> Option A

4. Quick Check:

   Label = Describe input + accessibility [OK]

Hint: Labels describe inputs clearly and help screen readers [OK]

Common Mistakes:

• Confusing labels with placeholders
• Thinking labels style inputs
• Assuming labels submit forms

2. Which of the following is the correct way to associate a label with an input field using the for attribute?

easy

A. Email

B. Email

C. Email

D. Email

Solution

1. Step 1: Check label's for attribute and input's id

   The label's for attribute must match the input's id to link them.

2. Step 2: Verify correct syntax

   <label for="email">Email</label><input id="email" type="text"> uses for="email" in label and id="email" in input, which is correct.

3. Final Answer:

   <label for="email">Email</label><input id="email" type="text"> -> Option D

4. Quick Check:

   Label for = Input id [OK]

Hint: Label's for must match input's id exactly [OK]

Common Mistakes:

• Using for on input instead of id
• Mismatching for and id values
• Using id on label instead of for

3. What will the following HTML code display inside the input box when the page loads?

<label for="username">Username</label>
<input id="username" type="text" placeholder="Enter your username">

medium

A. The text 'Username' inside the input box

B. The text 'Enter your username' inside the input box as a hint

C. An empty input box with no text

D. The label 'Username' inside the input box

Solution

1. Step 1: Understand placeholder attribute

   The placeholder attribute shows example text inside the input as a hint, not actual value.

2. Step 2: Check label vs placeholder roles

   The label text appears outside the input box; placeholder text appears inside as a hint.

3. Final Answer:

   The text 'Enter your username' inside the input box as a hint -> Option B

4. Quick Check:

   Placeholder = hint text inside input [OK]

Hint: Placeholder shows hint inside input, label is outside [OK]

Common Mistakes:

• Thinking label text appears inside input
• Confusing placeholder with input value
• Expecting input to be pre-filled

4. Identify the error in this HTML snippet:

<label for="phone">Phone Number</label>
<input placeholder="Enter phone number">

medium

A. The label's for attribute does not match input's id

B. Label element should be inside the input element

C. Placeholder attribute is not allowed on input

D. The input is missing a type attribute

Solution

1. Step 1: Check label's for attribute and input's id

   The label's for attribute value "phone" does not match any id on the input (input has no id).

2. Step 2: Verify other attributes

   Placeholder is valid on input; type defaults to text.

3. Final Answer:

   The label's for attribute does not match input's id -> Option A

4. Quick Check:

   Label for = Input id [OK]

Hint: Label's for must match input's id exactly [OK]

Common Mistakes:

• Omitting id on input
• Mismatching for and id values
• Using id on label instead of for

5. You want to create a form input for "Email" that is accessible and user-friendly. Which of the following is the best practice?

hard

A. Email

B. Email

C. Email

D. Email

Solution

1. Step 1: Ensure label is linked to input

   Using for="email" in label and matching id="email" in input links them for accessibility.

2. Step 2: Use placeholder as helpful hint

   The placeholder gives a clear example inside the input without replacing the label.

3. Step 3: Confirm input type is correct

   Using type="email" helps browsers validate and show correct keyboard on mobile.

4. Final Answer:

   <label for="email">Email</label><input id="email" type="email" placeholder="Enter your email address"> -> Option C

5. Quick Check:

   Label linked + placeholder hint + correct type = best practice [OK]

Hint: Link label with for/id and add placeholder for hints [OK]

Common Mistakes:

• Not linking label and input properly
• Placing label after input without for/id
• Omitting input type or placeholder
