How we design questions

These are just a small sample from our library of 10,000+ questions. The actual questions on this HTML/CSS Online Test will be non-googleable.

🧐 Question
Easy Background Properties	Try practice test
Consider the following shorthand CSS example: background: #f7f7f7 url(jolie.jpg) no-repeat scroll 0px 0px; Which of the following show the individual background properties represented by the shorthand:
Easy Colorful sentences	Try practice test
Our intern is writing a colorful blog post, and has written the following code. What colors will the sentences be? A: Sentence 1 will be gray, Sentence 2 will be pink. B: Both sentences will be gray. C: Sentence 1 will be pink, Sentence 2 will be gray. D: Both sentences will be pink. E: The code does not make sense; will throw an error.
Easy Links	Try practice test
In the following HTML, what will be the color of link with class "mark"
Medium Let's Hack CSS Property	Try practice test
Consider the following HTML and CSS: Which additional CSS rule(s) will render the following image? Choose ALL that apply. A: div{ flex-direction : column; align-items : center; } B: div{ flex-direction : row; align-items: center; } C: div{ flex-direction: column; justify-content: center; } D: div{ flex-direction: row; justify-content: center; }
Easy Registration Queue Logic Queues	Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount. For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition. ⚠️⚠️⚠️ Note: - The first line of the input is the length of the array. The second line contains all the elements of the array. - The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function. - You need to "print" the final result (not return it) to pass the test cases. For the example discussed above, the input will be: 5 20 70 -40 30 -10 Your code needs to print the following to the standard output: 20 70 30 -40 -10
Medium Visitors Count Strings Logic	Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. Example: Input: WWMMWWCCC Expected Output: 4W3C2M Explanation: ‘W’ has the highest count, then ‘C’, then ‘M’. ⚠️⚠️⚠️ Note: - The input is already parsed and passed to a function. - You need to "print" the final result (not return it) to pass the test cases. - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’. - If any of them have the same count, the output should follow this order - M, W, C.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment HTML/CSS Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

HTML/ CSS Hiring Test FAQs

About HTML/ CSS Job Roles

HTML (HyperText Markup Language) is the most basic building block of the Web. It defines the meaning and structure of web content. Other technologies besides HTML are generally used to describe a web page's appearance/presentation (CSS) or functionality/behavior (JavaScript).

HTML developers are responsible for the complete end-to-end coding of websites. They provide technical support to users, direct projects, code websites, develop web-based applications, and perform testing on websites. They work with other coders, designers and content developers, which means that communication skills are important. HTML developers must be able to translate designs into code and write technical documentation.

CSS developers are web professionals whose primary responsibility is to deliver a polished and styled product to a user's browser. Almost every website uses CSS. Most frontend or even full-stack developers could write the CSS code. But not all of them can fix every CSS bug or implement designs without convoluting HTML code or relying on JavaScript unnecessarily.

A HTML/ CSS Developer's responsibilities would typically include:

Translation of designer mock-ups and wireframes into front-end code
Front-end integration with a back-end framework
Optimize application for maximum speed and scalability
Assure that all user input is validated before submitting to back-end
Build reusable code and libraries for future use
Integrate data from various back-end services and databases
Cooperate with web designers to match visual design intent

Can I evaluate JavaScript along with HTML/ CSS?

Yes. We support evaluating JavaScript and HTML/ CSS in the same assessment. You can review our standard ready-to-go JavaScript, HTML/ CSS test to understand how the assessment would be designed. For customized assessments, we design the questions as per your job description and the final test will evaluate JavaScript, HTML/ CSS and coding skills together.

Can I evaluate frontend frameworks along with HTML/ CSS like React/ Angular/ Vue?

Yes. You can evaluate multiple skills in a single assessment. You can check our standard React, Angular, Vue assessments to get a sense of what questions would be asked. You can get a custom assessment designed that has questions to evaluate all the must-have skills of your job description. So for a standard React developer role, the test will have questions to evaluate React, JavaScript, HTML/ CSS and coding skills.

Can I combine multiple skills into one custom assessment?

Yes, absolutely. Custom assessments are set up based on your job description, and will include questions on all must-have skills you specify. Here's a quick guide on how you can request a custom test.

Do you have any anti-cheating or proctoring features in place?

We have the following anti-cheating features in place:

Non-googleable questions
IP proctoring
Screen proctoring
Web proctoring
Webcam proctoring
Plagiarism detection
Secure browser
Copy paste protection

Read more about the proctoring features.

How do I interpret test scores?

The primary thing to keep in mind is that an assessment is an elimination tool, not a selection tool. A skills assessment is optimized to help you eliminate candidates who are not technically qualified for the role, it is not optimized to help you find the best candidate for the role. So the ideal way to use an assessment is to decide a threshold score (typically 55%, we help you benchmark) and invite all candidates who score above the threshold for the next rounds of interview.

What experience level can I use this test for?

Each Adaface assessment is customized to your job description/ ideal candidate persona (our subject matter experts will pick the right questions for your assessment from our library of 10000+ questions). This assessment can be customized for any experience level.

Does every candidate get the same questions?

Yes, it makes it much easier for you to compare candidates. Options for MCQ questions and the order of questions are randomized. We have anti-cheating/ proctoring features in place. In our enterprise plan, we also have the option to create multiple versions of the same assessment with questions of similar difficulty levels.
