Top HTML Interview Questions and Answers for Freshers and Experts
HTML (HyperText Markup Language) is the fundamental building block of web development. Whether you’re a fresher stepping into the tech world or an experienced developer looking to refresh your basics, mastering HTML is essential. It is often the first topic covered in web development interviews, making preparation in this area crucial for any frontend or full-stack role.
This blog on Top HTML Interview Questions and Answers for Freshers and Experts is designed to help candidates at all levels confidently prepare for job interviews. From simple questions about tags and attributes to complex concepts like semantic HTML, accessibility, and new features in HTML5, this guide will walk you through the most frequently asked and impactful questions that hiring managers love to ask.
Why Learn HTML for Interviews?
HTML is not just a markup language. It is the foundation of every webpage. Even modern frameworks like React, Angular, or Vue render HTML at the core. Interviewers want to see if you understand how web pages are structured, how elements behave, and how HTML works in harmony with CSS and JavaScript.
Whether you're applying for a position as a front-end developer, UI/UX designer, WordPress developer, or full-stack engineer, HTML questions are almost always a part of the technical screening process.
HTML Interview Questions for Freshers
1. What is HTML?
Answer: HTML stands for HyperText Markup Language. It is used to create the structure of web pages using elements like headings, paragraphs, images, links, and more.
2. What is the difference between HTML and HTML5?
Answer: HTML5 is the latest version of HTML. It includes new semantic elements (<header>, <footer>, <article>), multimedia support (<audio>, <video>), and improved APIs like canvas, local storage, and geolocation.
3. What is a tag in HTML?
Answer: A tag is a keyword enclosed in angle brackets that defines the beginning and end of an HTML element (e.g., <p>Paragraph</p>).
4. What is the purpose of the <DOCTYPE html> declaration?
Answer: It defines the HTML version and helps the browser render the page correctly. For HTML5, it is written as <!DOCTYPE html>.
5. What is the difference between <div> and <span>?
Answer: <div> is a block-level element used for grouping sections, while <span> is an inline element used for styling a part of text or inline elements.
Intermediate to Advanced HTML Interview Questions
6. What is semantic HTML?
Answer: Semantic HTML uses meaningful tags (like <article>, <section>, <nav>) to describe the content, making it more readable for developers and accessible for screen readers and search engines.
7. What are void (self-closing) elements in HTML?
Answer: Void elements do not have a closing tag. Examples include <img>, <input>, <br>, and <hr>.
8. How is HTML different from XML?
Answer: HTML is designed for web page layout, while XML is used for storing and transporting data. HTML is more lenient with errors, whereas XML is strict and case-sensitive.
9. What is the difference between id and class attributes?
Answer: An id is unique for a single element, while a class can be applied to multiple elements. IDs are used for single-item styling or DOM targeting, whereas classes help in grouping and styling multiple elements.
10. What is the use of the alt attribute in images?
Answer: The alt attribute provides alternative text for images when they cannot be displayed. It also helps screen readers understand the image content, enhancing accessibility.
HTML5-Specific Interview Questions
11. Explain the difference between <section> and <article>.
Answer: <section> defines a thematic grouping of content, while <article> represents independent, self-contained content like blog posts or news articles.
12. What is the purpose of the <canvas> element?
Answer: The <canvas> element in HTML5 allows drawing graphics, animations, and visualizations using JavaScript.
13. How does local storage work in HTML5?
Answer: HTML5 introduces localStorage, allowing you to store data in the browser with no expiration time. It helps in storing user preferences or app data even after the browser is closed.
Why Interviewers Ask HTML Questions
