38. Top 3 Interview Questions and Study Plan (Interview Q&A)

The top questions asked in job interviews and their precise answers

Real-life analogy

An interviewer doesn't check how many tags you have memorised; they check whether or not you know how to write clean, modern and secure code.

Explanation

The top 3 most frequently asked questions:

Q. 1: What is the main difference between HTML and HTML5? Answer: HTML5 added new semantic tags (header, article), video/audio support, local storage and new inputs, all without any third-party software.

Q. 2: What are Empty Tags (Void Elements)? Answer: Tags that have no closing tag and have no text placed inside them, such as <br>, <hr>, <img>, <input>.

Q. 3: What is the difference between HTML and XHTML? Answer: XHTML has the strict rules of XML (every tag must be closed). HTML5 is more flexible and modern.

Golden rules

Always keep proper indentation in your code.

Common mistake

Saying in an interview that 'HTML is a programming language'. Always say that it is a markup language.

Example code

<!DOCTYPE html>
<html>
<body style="font-family: sans-serif; padding: 20px;">
  <div style="border-left: 4px solid #10b981; padding-left: 12px;">
    <h3 style="color: #065f46; margin: 0;">Congratulations! The entire HTML course is complete! 🎉</h3>
    <p style="font-size: 13px; color: #334155; margin-top: 4px;">
      Now you can build a complete, responsive and semantic web page on your own.
    </p>
  </div>
</body>
</html>
