To help you master your interviews, here are some of the most often asked HTML interview questions. So hurry ahead and get started on your studies!

1.What is the purpose of HTML encoding a URL?

ANS:Because URLs are only conveyed over the Internet using the ASCII character set, they must be encoded to transform non-ASCII characters into a format that can be used on the Internet. If a URL contains characters that are not part of the ASCII character set, it must be transformed. Non-ASCII characters are replaced with " percent " and hexadecimal digits.

2.In HTML, what are entities?

ANS:HTML character entities are used to replace reserved characters in the document. Entities can also be used to substitute characters that aren't on your keyboard. Because some HTML characters are reserved, some characters are replaced.

5.What is the benefit of reducing white space?

ANS:In HTML, white spaces are a blank sequence of space characters that are processed as if they were a single space character. You can indent lines of text without worrying about numerous spaces because the browser combines several spaces into a single space. This allows you to better structure the HTML code and make it more readable.

6.Is there a way to keep list components in an HTML file straight?

ANS:You may keep the list elements straight by using indents. You can easily discern the various lists and the components they contain if you indent each sub nested list in further than the parent list.

7.Describe the main differences between the LocalStorage and SessionStorage objects.

ANS:The following are the main distinctions between localStorage and sessionStorage objects: The data is stored in the localStorage object with no expiration date. The sessionStorage object, on the other hand, only keeps data for one session. When a browser window is closed, data in a localStorage object is not deleted. In the case of sessionStorage objects, however, the data is destroyed when the browser window is closed. SessionStorage data is only visible in the browser's current window. The data in the localStorage, on the other hand, can be shared across several browser windows.

8.What is the point of incorporating alternate text into images?

ANS:Using alternate texts serves to clarify what the image is about. It can be complicated and difficult to figure out which hotspots connect to which links during an image mapping. These alternative texts are used here to provide a description for each link, making it simple for readers to grasp the hotspot links.

9.What exactly is a marquee?

ANS:The scrolling lettering on a web page is called marquee. It automatically scrolls the image or text up, down, left, and right. Within the  tag, you should add the text you want to scroll.

ANS:You can add code comments to your HTML document to make the code easier to read. These aren't visible in the browser, but they can be useful for noting what a portion of HTML is for yourself and other developers. !– denotes the beginning of the comment, and — > denotes the end. Even if it contains proper HTML, everything in the middle will be ignored.

16.Are HTML tags and elements interchangeable?

ANS:No. A opening tag, which may or may not contain text, and a closing tag define HTML elements. < h1>Heading 1

17.What is the benefit of reducing white space?
