Programming in HTML5 with JavaScript and CSS3 — Question 28

You are developing a customer contact form that will be displayed on a page of a company's website. The page collects information about the customer.
If a customer enters a value before submitting the form, it must be a valid email address.
You need to ensure that the data validation requirement is met.
What should you use?

Answer options

• A. <input name="email" type="input" required="required"/>
• B. <input name=email" type="url" required="email"/>
• C. <input name="email" class" email"/>
• D. <input name="email" type="email"/>

Correct answer: D

Explanation

The correct answer is D because using type="email" ensures that the browser will validate the input as a proper email format before submission. Option A uses type="input" which does not enforce any specific format, B uses type="url" incorrectly for email validation, and C has a syntax error with class" email" that prevents it from functioning correctly.
