I’ve put together a helpful list of HTML interview questions which can help you prepare for your future job interview. Before we begin, let's talk about HTML a little bit. HTML, while fairly standard in its execution, still has some stylistic and personal differences when you are speaking from one professional to another. For example, small things, like do you use a span or an em HTML block when trying to replace it with an image (meaning no text is inside that HTML block). There are many people who have specific preferences about this and reasons as to why. Usability and accessibility is one of them. But for the most part, as long as you know some of the area’ s for which there are some personal approaches, you’ll be absolutely fine going into your interview.

HTML Interview Questions & Answers 1. What is HTML to you? HTML to me is the final document that gets read by modern web browsers. In essence, everything is trying to get itself down to the HTML page. No matter if we’re working in a WordPress environment or maybe even a custom application environment. The browser is always looking to render from HTML. So it is the core communication type for us humans telling browsers what to display and how to display it. That then becomes our communication line for consumers and customers who are looking to access our company website or application. 2. How do you define a navigation element? A navigation element can be defined in a couple of different ways. Using HTML5 you could use the NAV element, which would let the browser know this area is specifically used for holistic navigation. Using more historical methods for defining navigation, you would use an HTML div block and then use the ID “navigation” or “nav” to define its styling and presentation to the user. 3. What does OL stand for? OL is part of the list family, for defining and displaying lists to users. It is part of the oldest forms of HTML elements. OL stands for Ordered List, in which the list is displayed in an ordered fashion. 4. What does LI stand for? Li is part of the list family, for defining and displaying lists to users. It is part of the oldest forms of HTML elements. LI stands for List Item, in which the list is part of one of the items in the list. For example, lists usually have many components to them, call it a number of 5 list items. LI is one of those list items. 5. What does the BR tag do? BR tags essentially stand for a break. It means that you want to let the browser know to place whatever is coming after that break tag onto a new line on the page. Similar to what we experience when we use the return or enter button inside of a Word document. It places a new line break onto the page. 6. What is a P tag? The P tag stands for paragraph. It is used to let the browser know a couple of things. First, it lets the browser know that it is a content element, which is helpful for SEO and also beneficial for all readers. Second, it lets the browser know that after every paragraph tag ends that there may be a line break on it. So that way you don’t have to end up using the break tag every time. 7. What is accessibility in HTML? There’s a large discussion about accessibility happening at all times. But the general practice is knowing how to design HTML pages in ways that provide those with handicap or disabilities, the ability to read and understand what’s on the Website. It's really important to understand that not everyone is able to consume content and materials on Websites in the same ways. Generally speaking, accessibility is just ensuring that your HTML page structure is built in a fashion that is up to par with web standards, meaning that you aren’t using HTML elements for anything but their intended purpose. Because of that, it's important to understand the W3C web standards and how that relates to what you need to build when talking about HTML pages. 8. What does the HEAD element do? The HEAD element lets the browser know that certain parts of the HTML definitions are for the browser only and not for the user. For example, META tags go into the HEAD element. These are things which render on the page display itself but not on the part of the HTML document which the user sees. Communication needs to be had to the browser to let it know where to find certain parts required for the page to render. META tags, CSS files, JavaScript files and more often go into the HEAD element of the HTML document. 9. What is the FOOTER element? The FOOTER element is part of the HTML5 standard. It lets the browser know that anything within the element is part of the footer display of an HTML page. This means contact information, sometimes navigation and other holistic information goes within this element. It is often repeated multiple times throughout the entire website or document, which is helpful for the browser to know. 10. What is inline CSS? Inline CSS is when CSS styles are part of the HTML element or block itself. It is usually called by using the style tag within the HTML carats. It is questionable as to whether this approach is the right approach for CSS enthusiasts. So while it is still often used, it is not essentially the proper way of defining styles onto HTML elements. 11. How does HTML and CSS work together? HTML and CSS work together hand in hand. They must act together in order to display most modern websites. HTML elements and their ID’s or classes must be called in the CSS files themselves. So the way that HTML files are structured is similarly how CSS files are structured. 12. How do you call a CSS class in HTML? To call a CSS class in HTML you would use the class=“” tag within the HTML element you are trying to style. 13. How do you call a CSS ID in HTML? To call a CSS ID in HTML you would use the id=“” tag within the HTML element you are trying to either style or define. 14. Which one of these is not a real HTML element: HEADER, FOOTER, NAV, BODY While most of these are HTML5 elements, only one is not real, the BODY element. It is actually the CONTENT element for which we would want to call. The rest are absolutely real HTML5 blocks that can be used in the HTML document. 15. What is the container ID usually used for? A container ID is often used to define a set width for the content on a Website. For example, we want all of our content to line up, from the navigation to the main article information to the footer. We often would use a container ID to define what that width is holistically so that everything lines up seamlessly. 16. How do you generally design your HTML for mobile? Designing HTML for mobile is often times best done by following standard W3C practices. There is no specific way within HTML itself to design for mobile, only within CSS using media queries and device types. But you can define some custom information in your META tags to help with the display on certain mobile devices. Generally speaking, your best bet is to stay within the W3C guidelines and that will help browsers translate your content for mobile devices when being accessed. 17. What needs to be considered with HTML as it relates to many screen devices and widths? The things that need to be considered are proper definitions of the HTML blocks and then proper definitions of the container widths and how they respond on multiple screens. Aside from that, not much else needs to be considered as a core until you get into responsive HTML needs. 18. What is responsive HTML? Responsive HTML is the act of knowing that you want one HTML document to be responsible for serving the content to all browser widths. Back in the day, the way that this used to be handled is to have mobile HTML documents. These documents would have a “m.website.com” type of declaration to the website. Which would usually do to a new type of Website designed specifically for mobile. But once responsive HTML became more widely adopted, it allowed for one HTML document to serve all device needs. This made it dramatically easier for developers to handle their code, thus allowing for greater products to be built. Meaning, more time spent making a great product for their customers/consumers versus trying to handle the code. 19. What is nested HTML elements? Nested HTML elements is a practical part of any HTML document. It simply refers to the fact that you’ll have to have many HTML elements within one another. For example, when defining a list. You’ll have the OL or UL property, then an LI property within it, then finally you may have a P tag within that. 20. How do you manage HTML projects with multiple developers? HTML projects should always be managed under the pretense that there will be future development on the project you are working within. So remembering that you are not going to be the only one managing the code is important. From declaring comments on the code to allow for other engineers to better understand what you did and why, to checking those projects into Git or some other type of version control system. 21. What part of the following is the HTML involved with: model, view or controller? View. Mode, View, Controller also stands for MVC. It is the type of application framework for which many robust applications are built. HTML is a core part of any web application and sometimes even mobile applications. The view part is what is considered to be where HTML comes into play. If you are working within an application structure, like Rails for instance, you’ll usually see a “views” folder part of the application tree that is where most HTML files are stored. Prepping for an HTML interview I hope this guide helped you understand some questions that you might experience going into an interview. At its core, being prepared for an interview session where they bring up HTML is not too difficult. You won’t be asked about extremely complex HTML questions. Generally speaking, most times employers want to know that you have a basic understanding of HTML due to the fact that almost everyone is now exposed to it. The reality is that HTML is quite easy to learn, there’s a wide variety of resources available today and even if you don’t have the most robust knowledge about HTML, you’ll still be able to get employed and get the opportunity to learn. If you have any other interview questions that you’d like to see listed here, please feel free to contact me. As with all interview questions, it's important that you treat them as mock answers. Meaning, you should be putting together your own set of answers based on the ones that I listed. Practice with a friend or family memb er to hone in on your delivery. The more confident you are about your knowledge going into the interview, the better off you’ll be.
