Basic HTML Interview Questions for Freshers (With Answers)
The following are some commonly asked HTML interview questions and answers for freshers. These questions also cover basic HTML and CSS concepts to help you build a strong foundation in web development:
1. What is HTML?
This is one of the most commonly asked HTML interview questions for both freshers and experienced professionals. Having a clear understanding of the basics is very important.
HTML, which stands for HyperText Markup Language, is the standard language used to create and structure web pages on the World Wide Web. It helps browsers display content such as text, images, tables, links, and multimedia in a proper format.
HTML makes web pages interactive and organized by using different tags and elements. Web pages created using HTML are usually saved with the .html extension.
2. What are the main features of HTML?
HTML has several important features that make it widely used for web development:
- HTML is a markup language used to create and structure web pages.
- It is simple, beginner-friendly, and easy to understand.
- HTML allows developers to add images, videos, audio, tables, and links to web pages.
- It is platform-independent and works on operating systems like Windows, Linux, and macOS.
- HTML is not case-sensitive, so tags can be written in uppercase or lowercase.
- It helps create interactive web pages by connecting different pages through hyperlinks.
3. What are HTML tags, and how to use them?
HTML tags are special keywords used to create and structure web pages. They define how content should appear in a web browser. Most HTML tags consist of an opening tag, content, and a closing tag, while some tags are self-closing.
HTML documents mainly contain tags and content. A web browser reads the HTML code from top to bottom and left to right to display the page correctly. Tags can also include attributes that provide additional information or functionality.
<tag> content </tag>Content is placed between HTML tags to display text, images, links, tables, and other elements on a web page.
4. What is the difference between HTML elements & HTML tags?
Here is a tabular comparison of HTML elements vs HTML tags to understand the differences between the two easily:
| HTML Elements | HTML Tags |
| An HTML element is a complete component of a web page that includes a start tag, attributes, content, and an end tag. | HTML tags are used to define the beginning or end of an HTML element. |
| Elements contain a start tag, content, and an end tag. | HTML tags begin with < and end with >. Anything written between them is called a tag. |
| HTML elements hold the content displayed on a web page. | HTML tags hold and define HTML elements. |
| HTML elements define the overall structure and content of the page. | HTML tags work like keywords, where each tag has a specific meaning. |
| Example: <p>This is a paragraph.</p> | Example: <a> represents the opening anchor tag and </a> represents the closing anchor tag. |
5. What is HTML formatting?
HTML formatting is used to improve the appearance and presentation of text on a web page. It helps make content more attractive, readable, and meaningful for users.
HTML provides different formatting tags to style text in various ways, such as bold, italic, underlined, highlighted, or smaller text. These tags help organize content and improve the user experience.
Some commonly used HTML formatting tags are:
- <b> – Makes text bold
- <i> – Makes text italic
- <u> – Underlines text
- <mark> – Highlights text
- <small> – Displays smaller text
Example:
<b>Bold Text</b>
<i>Italic Text</i>6. Do all HTML tags have an end tag?
No, not all HTML tags have an end tag. Some HTML tags are self-closing tags, which means they do not require a closing tag.
For example, the <br> tag is used to insert a line break, and the <img> tag is used to add an image to a web page.
7. Which HTML tags are used to display the data in tabular format?
To display the data in tabular form, the following HTML tags are used:
| <table> | Represents a table |
| <tr> | Defines a row in a table |
| <th> | Used for a header cell in a table |
| <td> | Defines a cell in the table |
| <caption> | Represents the table caption |
| <col> | Used with <colgroup> element to specify each column property |
| <tbody> | Group the body content in the table |
| <thead> | Groups the header content in the table |
| <tfootr> | Groups the footer content in a table |
This is one of the most common HTML interview questions for freshers, as they should know about all types of tags used.
8. What are HTML attributes & how to use them?
Each HTML tag can contain attributes that affect how the tag behaves or appears on a web page. Attributes provide additional information about HTML elements.
For example, the type attribute in the <input> tag is used to specify whether the input field is a text box, checkbox, radio button, and more.
Attributes are written inside the opening tag, directly after the tag name. They are used only in opening or self-closing tags and never in closing tags.
Using Attributes:
<!-- Text field --><input type="text" />
<!-- Checkbox --><input type="checkbox" />
<!-- Radio button --><input type="radio" value="on" />9. What is the basic structure of an HTML template?

<html>
<head>
<title>Page Title</title>
</head>
<body>Page content</body>
</html>10. How many heading tags are there in HTML?

<h1>Heading no. 1</h1>
<h2>Heading no. 2</h2>
<h3>Heading no. 3</h3>
<h4>Heading no. 4</h4>
<h5>Heading no. 5</h5>
<h6>Heading no. 6</h6>11. How to create an HTML hyperlink?

Links in HTML can appear in different states:
- Unvisited Link – Displayed as blue and underlined
- Visited Link – Displayed as purple and underlined
- Active Link – Displayed as red and underlined
Syntax:
<a href="URL">Link Text</a>12. What is the difference between Block Level Elements & Inline Elements in HTML?

Here is a tabular comparison of block-level elements and inline elements to understand the differences easily:
| Block-Level Elements | Inline Elements |
| A block-level element occupies the full width available and always starts on a new line. | Inline elements only take up the space required by their content. |
| These elements create a new block or section on the web page. | These elements flow within the same line without starting a new line. |
| Examples: <div>, <section>, <form>, <nav> | Examples: <span>, <b>, <img>, <strong>, <a>, <input> |
13. What are HTML comments?
HTML comments are used to add notes or explanations inside an HTML document to make the code easier to understand. These comments are not displayed in the browser, but they help developers understand the purpose of a specific section of code.
An HTML comment starts with <!-- and ends with -->. Anything written between these symbols is ignored by the browser, even if it contains valid HTML code.
For Example:
<!-- This is a comment! -->
<!-- Comments spanning multiple lines -->
<!-- This part is ignored in the browser -->14. What is HTML5? What are new features in it that are not available with HTML?
HTML5 is the most recent version of the HyperText Markup Language (HTML). It is used to create and structure modern web pages and web applications.
HTML5's new features include the following:
- SVG, canvas, and other vector graphics are supported in HTML5. In older HTML versions, vector graphics required plugins like Flash, VML, or Silverlight.
- HTML5 supports multimedia elements like <audio> and <video> without requiring external plugins.
- HTML5 provides better support for modern JavaScript APIs and interactive web applications.
- HTML5 introduces semantic elements such as <header>, <section>, <article>, and <footer> for better webpage structure.
- HTML5 does not use SGML and has improved parsing rules for better compatibility across browsers.

For Example:
