Simple HTML Interview Questions
The top basic HTML interview questions for new hires are listed below:
What exactly is HTML?
Hypertext Markup Language, or HTML, was developed in 1991 by Berners-Lee. It is a markup language for building website templates or web pages that display material on the World Wide Web. There are several elements in it, and the HTML elements instruct the browser on how to display the content. With the use of HTML, text may be more dynamic and interactive. Add.html or.html to the end of the web page name to save an HTML page.
What qualities does HTML have?
The qualities of HTML include the following:
- It is a markup language that gives designers the freedom to incorporate text into web pages.
- It is simple to use and pick up.
- HTML can be used on Windows, Linux, Macintosh, and other operating systems.
- It allows programmers to interactively add images, video, and audio to web pages.
- Links can be added to web pages using HTML, assisting readers in finding material that interests them.
- It doesn’t care about the case. Tags may be used in either lowercase or uppercase.
Write the HTML template’s basic structure.
The basic structure of the HTML template is:
<html>
<head>
<title>Title of the page</title>
</head>
<body>content of the page</body>
</html>
How do HTML attributes work?
Additional details about HTML elements are provided through HTML attributes. They are defined immediately behind the tag name. They don’t show up in closing tags; only opening tags do.
Name/value pairs, such as name=”value,” are the norm for HTML attributes. Always put quotation marks around the attribute values. The name of the property to be given to the element is the value for the name parameter. The value represents the extent to of the property names are aligned across the element or the respective property’s value.
The following HTML attributes are some of the most often used ones: src, alt, id, and href.
Describe semantic HTML.
A coding style is semantic HTML. Instead of only establishing a webpage’s design or appearance, HTML markup is used to support the semantics or meaning of the material in web applications and webpages. It gives the code we write significance.
For example: <form>, <table>, and <article> these tags clearly defines its content.
What does the article HTML element mean?
The HTML “article” element describes autonomous and self-contained material independently distributable or reusable within a document, page, application, or website. It can be seen, used again, and distributed separately because it is not dependent on the record or webpage.
For example, syndication. The HTML article element is used in:
- Forum post
- Blog post
- Newspaper article
What differentiates an inline element from a block-level element?
The following are the distinctions between inline and block-level elements:
| Block-level Elements | Inline Elements |
| They start on a new line. | Do not start on a new line and can begin within a line. |
| Stretch to fill the full width available to them. | Take up as much width as necessary. Its width only extends as far as its tags define it. |
| They have a top and a bottom margin. | Inline elements do not have a top and a bottom margin. |
| Examples of block-level elements in HTML: <div>, <img>, <form>, <main>, <table>, <video>. | Examples of inline elements: <span>, <img>, <strong>, <code>, <input>, <time>, <i>. |
The best way to align text in HTML
The CSS text-align property is used to align HTML content on a webpage. It determines how the content of a block element or table-cell box will be aligned horizontally. In the horizontal direction, the text-align property functions similarly to the vertical-align. It performs on the text and block-related material, including buttons and graphics.
Below is the code to align text in HTML:
<!DOCTYPE html>
<html>
<head></head>
<body>
<h1>Heading</h1>
<p style=”text-align:center/left/right/justify;”>text</p>
</body>
</html>
