Basic HTML Interview Questions
Here is a list of basic HTML questions for interview and their answers explained in simple.
- What is the difference between HTML and HTML5?
HTML5 is the latest version of HTML. It supports new features like audio, video, canvas, and better error handling. It also supports semantic tags and works better on mobile devices.
- What are semantic tags in HTML?
Semantic tags describe the meaning of content. Examples include <header>, <footer>, <article>, and <section>. These tags make the code easier to read and help search engines understand the layout.
- How does the ‘div’ tag differ from the ‘span’ tag?
<div> is a block-level tag used to group large sections of content. <span> is inline and is used to style small parts of text within a line.
- What is the purpose of the ‘alt’ attribute in images?
The alt attribute provides alternate text if the image doesn’t load. It also helps visually impaired users by describing the image through screen readers.
- How do you create a hyperlink in HTML?
Use the <a> tag with an href attribute.
Example:
<a href=”https://example.com”>Click Here</a>. It links to another webpage or resource.
- What are void (self-closing) elements in HTML?
Void elements don’t have closing tags. Common examples include <br>, <img>, <input>, and <hr>. They are used when no content is needed inside the tag.
Note – HTML basic questions for interview often cover tags, elements, attributes, forms, and structure.
HTML Fresher Interview Questions
Here are some commonly asked HTML interview questions and answers for freshers and beginners.
- What is HTML and why is it used?
HTML stands for HyperText Markup Language. It is used to create and structure web pages. I use it to add text, images, links, and layout elements to websites.
- How do you structure a basic HTML document?
This is one of the most common HTML basic interview questions for freshers. Here’s how you should answer it.
Start with <!DOCTYPE html>. Then use <html>, with <head> for metadata and <body> for content. Inside <head>, include the title and links to stylesheets or scripts.
- What is the function of the ‘head’ and ‘body’ tags?
The <head> tag holds metadata, title, and links to CSS or JS files. The <body> tag contains everything that appears on the page—text, images, forms, and more.
- What is the use of the ‘title’ tag in HTML?
The <title> tag sets the name shown in the browser tab. It also helps search engines identify the page content.
- How do you insert an image in HTML?
Use the <img> tag with src and alt.
For example:
<img src=”photo.jpg” alt=”A red flower”>. It shows an image and describes it if it fails to load.
- What is the difference between ordered and unordered lists?
Ordered lists use numbers (<ol>), and unordered lists use bullets (<ul>). I choose based on whether the sequence matters.

I have used HTML to create structured pages with headers, footers, forms, and reusable components. I worked closely with CSS and JavaScript for building user interfaces.
- Describe a time you solved a layout issue using HTML.
Once, an image was overlapping text on mobile. I fixed it by wrapping the content in a <div> and adjusting structure. It worked after I rearranged the HTML blocks.
- How would you design a form that adapts to mobile screens?
I would use simple, stacked fields and label every input clearly. I wrap the form in a container and use media queries in CSS. I also use <input type=”tel”> for phone fields.

One project needed a custom table layout that looked like Excel. I had to work with many nested tables. I used clean HTML and split content wisely to avoid confusion.

I keep it simple. I explain what can be done in HTML and what needs CSS or JavaScript. If something isn’t practical, I suggest alternatives that still match the design goal.
- How would you approach refactoring old HTML code for a redesign?
First, I review the structure and remove unused tags. I replace outdated elements like <font> with CSS. Then I use semantic tags and clean indentation. I test on all screens.
HTML Interview Questions for 10 Year Experienced
If you are a senior-level professional, you might come across these HTML interview questions for experienced.
- How has HTML evolved during your career?
HTML was more static when I started. Over time, HTML5 added semantic elements, built-in form controls, and media support. Now, we can build more with less code and better accessibility.
- Describe your approach to reviewing or mentoring others on HTML code.
I check for clean structure, proper tags, and accessibility. I don’t just fix issues – I explain why something works or doesn’t. My goal is to help them think about maintainability.
- Tell me about a time you made a tough HTML-related decision on a project.
Once, I had to remove inline styles used heavily across old pages. It broke some layouts. I decided to move all styles to a CSS file and worked with QA to test everything.
- How would you lead a team in adopting new HTML5 features?
I start by showing how the new tags improve code. Then I update our templates and give short sessions to the team. I also review code regularly to support the shift.
Advanced HTML Interview Questions
Here are some advanced level HTML interview questions and answers to help you prepare.
- What are custom data attributes and how are they used?
Custom data attributes store extra information in HTML elements. They start with data-, like data-id=”123″. JavaScript can read them using element.dataset. I use them when I need to store data without showing it.
- How does the HTML parsing model work in browsers?
The browser reads HTML from top to bottom. It builds the DOM as it parses. If it finds CSS or JS, it may stop to process them. Malformed tags are corrected based on parsing rules.
- What are ARIA roles and why are they important?
ARIA roles help screen readers understand the purpose of elements. For example, role=”button” tells assistive tech this element works like a button. They improve accessibility, especially for custom components.
- How do you deal with cross-browser HTML compatibility issues?
I test early on Chrome, Firefox, Safari, and Edge. I avoid deprecated tags. I also use valid, clean HTML and check the layout in multiple viewports. For tricky parts, I add fallback solutions.
HTML Technical Interview Questions
HTML important interview questions are often technical. So, here are some common questions and their answers.
- What is the purpose of the ‘meta’ tag in HTML?
The meta tag provides metadata about the page. It is placed inside the <head> tag. Common uses include setting the character set, author info, or SEO-related content like description.
- How does the ‘viewport’ meta tag affect mobile responsiveness?
The viewport tag controls how a page appears on mobile devices. It helps scale content to match the screen size. Without it, pages may appear zoomed out or poorly formatted.
- How do you include external scripts and styles in HTML?
Use <link> to add external CSS files. For JavaScript, use the <script> tag with the src attribute. Place scripts at the bottom or use defer for better load performance.
- What’s the difference between ‘defer’ and ‘async’ in script loading?
defer waits for HTML to load before running the script. Scripts load in order. async loads scripts in parallel and runs them as soon as they’re ready. I prefer defer for predictable behavior.

Fun Fact – According to a 2024 Stack Overflow survey, over 53% of professional developers use HTML. This makes it one of the most-used languages worldwide.

I mostly use Visual Studio Code. It has great extensions for HTML, Emmet shortcuts, and live server preview. For testing, I rely on browser dev tools, Lighthouse, and screen readers for accessibility checks.
- How do you keep your HTML code clean and maintainable?
I write semantic HTML. I avoid deep nesting. I use meaningful class names and always close my tags. I also break large sections into reusable components when needed. Clean code is easier to read and debug later.

I follow proper indentation and use lowercase tags. I include the correct doctype at the top. I avoid inline styles and use external stylesheets. I also use alt attributes for images and test my layout across screen sizes.
- How do you ensure accessibility while developing in HTML?
I use semantic tags like <nav>, <main>, and <button>. I label form inputs clearly using <label>. I add alt text to every image. For dynamic elements, I sometimes add ARIA roles to describe the behavior. I also test using keyboard navigation.
HTML 5 Interview Questions
You might also come across HTML5 interview questions like these during technical rounds or web development interviews.
- What are some new input types introduced in HTML5?
HTML5 added input types like email, tel, date, url, range, and color. These help browsers show the right keyboards or widgets and catch errors early.
- What is the purpose of the ‘canvas’ element?
The <canvas> tag lets you draw graphics with JavaScript. It’s used for charts, animations, and games. The tag itself is just a container—drawing is done using JS code.
- How does the ‘section’ tag differ from ‘div’?

Tips to Prepare for Your HTML Interview
Before your HTML interview, don’t just memorize tags. Understand how HTML is used in real projects and be ready to explain your choices.
- Rebuild a real website layout. Pick any popular site (like a blog or news page) and recreate its layout using only HTML. Skip the styling – focus on structure. This helps you think in terms of content sections and semantics.
- Practice without using CSS or JavaScript. Can you build a working form, a navigation menu, or a data table using HTML only? This reveals your true grasp of markup.
- Explain your HTML out loud. Take any code you have written and talk through why you used each tag. In interviews, you will often need to justify your choices clearly.
- Know accessibility tags and patterns. Interviewers value developers who understand real user needs. Study aria-label, role, tabindex, and how screen readers interpret structure.
- Debug using browser dev tools. Learn to inspect elements, check nesting, and view applied styles. Interviewers may ask you to fix something in real time.
- Use HTML validators. Test your code at validator.w3.org. It shows structural issues you might miss and helps form better habits.
- Practice common interview questions and answers. Go through frequently asked HTML questions. Focus on basics, advanced topics, and how HTML is used in actual projects.

How to Answer HTML Interview Questions?
How you answer matters as much as what you know. Even if you understand HTML well, struggling to explain it clearly can hurt your chances. Here are a few tips to answer HTML interview questions.
- Start with a clear definition. If asked “What is semantic HTML?”, begin with a short explanation before getting into examples.
- Give a real example. Interviewers love it when you say, “In my last project, I used <section> to group related content.” It shows experience, not theory.
- Explain your reasoning. Don’t just say, “I used a <div>.” Say why you didn’t use a semantic tag and what problem it solved.
- Speak in plain terms. Keep it simple and accurate. Avoid buzzwords. You are being judged on clarity, not jargon.
- Be honest about what you don’t know. If you are unsure, say, “I haven’t used that much, but I’d look it up and test it.” That’s better than guessing.
