If you’re preparing for an interview to become an entry-level software engineer, there’s a good chance that either now or in the future, they will ask you questions about HTML.

What is HTML? – html interview questions

HTML stands for Hyper Text Markup Language. It is the most basic building block of the world wide web. HTML is basically a set of instructions that tell a computer what to display on a webpage.

When you visit a website, like Google or Facebook, it is being served to you as a bunch of HTML on a web server somewhere.

When you click a link to another page, it sends those instructions to your browser and then rewrites it to show you that page.

Question: Explain what is a DOM and how it works to create HTML? – html interview questions

A DOM is a tree-like data structure that represents the structure of a document written in HTML. An HTML document can be represented as a DOM tree.

A DOM can represent any document written in HTML. A DOM parser is a program which reads a document written in HTML, breaks it down into its constituent parts such as elements, attributes, etc.

and stores them in a data structure. The DOM is usually implemented as a tree data structure where each node in the tree may have zero or more child nodes.

Question: Explain what is the difference between an element and a tag in HTML?

An HTML Element is the basic building block of any webpage. The various elements include – <p>, <h1> etc. Elements are defined with an opening <tag> and a closing </tag> .

A Tag is the part of the HTML document that tells the browser what the element is. The various tags include <title>, <p> etc.

It is advisable to use meaningful naming conventions for your tags. This will help you keep track of your code and make it easier to read and understand.

Question: Explain what is an anchor, hyperlink, and anchor tag in HTML? – html interview questions

An anchor is a clickable link that takes you to a different page or a different part of the same page. The anchor tag is what is used to mark up a link and create the anchor.

The anchor tag has an attribute called “href” which is used to specify the address to which the anchor points.

When an anchor is clicked, the browser loads the specified address and navigates to the new page. The anchor tag can be used with other HTML elements such as images or lists.

An example of an anchor tag is a href=”https://www.example.com/”>My website/a>

Question: Explain what is a CSS and how does it work with HTML?

A CSS is a style sheet language used for describing the look and formatting of a webpage. It is used to define the colors, fonts, layout, and other visual aspects of a webpage.

The visual part of a webpage is called the layout or design. The CSS code is written in a separate file from the HTML code and is included in the HTML document using the “link” tag.

This is a great way to keep your code neat and tidy by separating the elements of the website into different files. However, you must keep in mind that the CSS file should be referenced in both the HTML file and the CSS file.

Question: Explain what is an ID and how does it differ from a class in HTML?  – html interview questions

An ID is a unique identifier that is used to identify one element from another. It is usually used to mark a heading or title or to mark an element that appears only once on a page.

A class is a generic identifier that is used to mark an element that can appear multiple times on a page. Using IDs instead of classes can be helpful in certain situations.

IDs can be used as links to images, which can be very helpful when creating a slider. IDs can also be used to identify a specific element on a page with an on-click event.

Classes can be used to style multiple elements on a page. This can be helpful when creating a consistent design throughout your site.

Is it possible to have a webpage without any HTML? – html interview questions

A webpage is always constructed using HTML. A webpage without any HTML would not be a webpage but only plain text. You can, however, use CSS to style your text without using any HTML.

Can you name 3 other tags that display text on a webpage?

An example of a tag used to display text on a page would be <strong> or <blockquote>. <strong> is used to denote important or strong text while <blockquote> is used for long passages of text that are quoted from another source.

There are many other tags used for displaying text such as img> for images, ul> for bulleted lists, ol> for numbered lists, and table> to display tabular data.

There are many other tags used in HTML that are commonly used during interviews. Be sure to research them and prepare for these common questions before your next interview.

<strong> can be used for important text. <blockquote> can be used for long passages of text. <img> can be used for images, <ul> can be used for bulleted lists, <ol> can be used for numbered lists and <table> can be used to display tabular data.
