Most Asked HTML Interview Questions & Answers 2022

Hypertext Mark-up Language or HTML is known, to all, as the “backbone of the world wide web”. Since the beginning of the command, it has been around governing what we see and how we see it on the internet. HTML is a foundation coding language used to create and structure web pages displayed on a browser. Websites are nothing but an aggregation of web pages, and most of these web pages are stored as HTML files. 

As a mark-up language, HTML differs from other programming languages such as Python or Java. HTML is a declarative language, meaning an HTML code is a statement ‘declaring’ what goes on a webpage. Most other programming languages are computational. However, nothing on the internet can exist without HTML, and it plays a crucial role in user experience. HTML’s versatility and universal importance have ensured its continuing relevance even in 2022. It is hands down the most popular mark-up language in the digital world. 

This is perhaps why most front-end developers begin their knowledge journey by learning how to code on HTML. And the language continues to enjoy a stronghold among most developers and programmers, especially those involved in UI-UX designing and software development. 

This article aims to provide an overview of the career prospects in HTML and software development and the most common HTML and HTML5 interview questions in 2022. Read on to find out.

Why Is HTML Important? 

HTML contains constitutional information that helps a browser load a page- like text, links, images, paragraphs, etc. On top of that, several features of HTML, and the recent HTML5, explains its continual popularity. First, it is a highly adaptable and versatile language and enjoys a kind of monopoly in the world of mark-up languages. Second, it is platform-independent, which means that the language can run on any browser or operating system. Finally, one of the best features of HTML is that it can run dynamic scripts via Java or JS, thus allowing the creation of dynamic elements. 

HTML developers are highly sought-after by most digital companies, big and small. Moreover, HTML skills find their utility in UI-UX design, app development, and many other sectors. Thus, we can say that HTML professionals provide the face of whatever we see on the internet.

HTML Interview Questions in 2022

Below are some of the most common HTML interview questions and HTML5 interview questions in 2022, along with the best answers.

1. How can we insert an image in HTML?

An image is added to a web page with the help of the <img> tag. In HTML, images are technically linked to a web page, and this tag creates a holding space for the linked image. The <img> tag only has attributes and does not have a closing tag. It is usually empty. There are two necessary parameters for the <img> tag – src – the path to the referenced image, and alt – an alternate text for said image.

2. What is CSS? How can it be linked to HTML?

CSS, or Cascading Style Sheets, is used to format the overall layout of the HTML web page. If HTML is the skeleton of the web page, then CSS determines the appearance of the body – the skin, hair, eyes, etc. CSS helps the developer decide such aspects as the color, font, text spacing, position of elements, background images, device-based display, etc. 

There are three ways to link a CSS file to HTML:

  • Inline style, which puts the style attribute inside the HTML elements. 
  • Internal style, which puts a <style> element in the <head> section.
  • External style, which adds a <link> element to an external CSS file. This is also the most commonly used way to link CSS to HTML.

3. What do you understand by doctype in HTML5?

Doctype refers to the HTML document type in use. It informs the browser of the type of HTML document that it is about to load. In HTML5, the <!DOCTYPE> syntax was simplified to <!DOCTYPE html>

4. How does HTML5 differ from HTML?

HTML5 was built to smoothen the web experience of developers and end-users. Hence, HTML5 differs from its earlier versions in functionality.

  • HTML5 supports SVG, canvas, and other vector graphics. Earlier, HTML did not directly support the use of vector graphics. The only way vector graphics could be linked is by using them in external formats like VML.
  • Unlike HTML, HTML5 is no longer based on SGML. This has improved compatibility with better parsing rules.
  • In HTML, Javascript could run only in the browser interface thread. But, HTML5 allows Javascript to run with a web browser. 
  • HTML5 allows the use of SQL databases to temporarily store data, whereas, in the earlier versions, data could be stored only in the browser cache.

5. What is meant by attribute?

Attributes are used to provide extra information about HTML elements. Every HTML element comes with attributes. Attributes always have a start tag. They are used in name-value pairs, represented as name= “value”.

6. What is the syntax to increase button size?

Button size can be increased by using 

<button type=“button”>Click Here!</button>

7. What is the process of connecting HTML to a database with MySQL? 

First, we need to filter our HTML form fields for the contact us web page. Then, we have to create a database and table in MySQL, followed by an HTML form. Finally, we have to create the PHP page to add the contact us HTML form data to the MySQL database. 

8. Explain the difference between HTML tags and elements.

Tags are represented by angle brackets < and >. They mark the beginning and end of an HTML element. HTML elements are the text written between tags and denote the content of the web page.

9. How can we deal with the Out of HTML5 Storage Space error?

This is the HTML5 offline storage mega error, and it can be cleared with a few simple steps. We go to Chrome settings and click on content settings. In the advanced settings pop-up, we need to choose the All Cookies and Data option. Here we need to clear the mega.nz cookie.

10. What is the drag and drop concept in HTML5?

The drag and drop functionality is one of the key upgrades that HTML5 comes with. It allows the user to drag an item from one place and drop it to another. The most commonly used drag and drop features are moves, copy, and link. To use this feature on an image, one has to make the image draggable. This is done by setting the image attribute to true:

type=<img draggable=“true”>.
