HTML 5 Interview Questions and Answers 2024

In the world of markup languages, HTML 5 has gained repetition since its inception. HTML stands for "Hypertext Mark-up Language," and HTML 5 is the latest version of HTML.

HTML 5 is called the structural block or component of a website. HTML is quintessential to developing and constructing a website. In general, HTML is combined with two other scripts: Cascading Style Sheets (CSS) and JavaScript.

Programmers use HTML 5 to give structure to a website, and along with that, they use CSS to provide the website with a better presentation. They also use JavaScript, which helps the website work and perform normally.

Why Is HTML 5 So Popular?

HTML 5 provides such a platform to a programmer that he or she can again design any website without using browser plugins. It not only helps in delivering animation for applications, but it also searches well for music, videos, movies, and so on.

Apart from all these qualities, one can use HTML 5 to construct highly complex applications that can easily run in any browser.

HTML 5 also serves as a cross-platform standard. In other words, it is supported by a huge variety of devices. From smartphones to smart TVs, HTML 5 can run any webpage seamlessly without interruption.

As a result, HTML 5 is gaining popularity in the field of software development. 

Is HTML 5 Better Than Flash And Silverlight?

It is one of the most frequently asked HTML 5 questions in the field of programming. Well, to answer this question, it is important to look at some facts about HTML 5. Currently, HTML 5 has successfully outshined Flash as a markup language for many devices, browsers, and various online platforms.

Most of the content owners are hesitant to use HTML 5 as it does not prevent copying. However, most of the containers do not choose Flash over HTML 5, but they choose a silver site over HTML 5.

Adobe, on the other hand, recently announced that it will no longer develop the Flash Player for mobile devices. But in contrast, they still have their hold on most of the video content and web pages. So, there is no such report of Adobe dying due to the adoption of HTML 5.

So this concludes that even if HTML 5 is being adopted by most of the content owners and creators in the market.

There is still some space for flash and Silverlight in the market, and indeed, they must do something to become marketable enough in the market compared to HTML 5.

Now let us define each of them:

:  the content of any self-contained web page is demonstrated or represented by this element's help.

<>: When a web page is designed or developed, then one of the most important things to notice and work on at the beginning is to create a space for HTML data. And this is the element used to represent or demonstrate the data of HTML.

The metadata is not shown on any webpage, as it is designed for the machine to read it. This is a piece of information that helps a browser learn about displaying certain contents and reloading pages.

In search engines, the metadata helps the search engine learn about the keywords and search-related topics and links.

9) Describe the best way to group form elements?

12) What do you mean by hyperlink?

Hyperlinks are those links that allow a person or user to jump from one web page to another page just by one click.

When the mouse's cursor is brought near any hyperlink, it turns into a hand symbol, which allows the user to click on the link to reach a specific page.

The math ML element is such an element that it is very helpful to encode every type of mathematical representation and mathematical notion in a high-quality visual display.

Using mathematical and scientific content is a tough job when it comes to a web page. But HTML 5 provides its users with various types of elements that will be helpful for them to create any type of content on the web.

No workers work dependently, and they do not rely upon any type of script further. They also make sure that the HTML page that is being scripted should not be interrupted performance-wise. After initiating the web worker, one can continue to do whatever they want to; they can click on something, select things they can click on, and they can take any action according to their requirements.
