Use our CSS test to hire the best

About the CSS test

Cascading Style Sheets (CSS) allows front-end developers to define the style of a website or web application to create a beautiful and appealing product for your users and visitors. Nevertheless, it can often be hard to find front-end developers who have deep and practical knowledge in CSS to deliver the desired results.

This CSS test evaluates candidates’ ability to understand both basic and advanced CSS properties. It also evaluates their skills in using CSS pre-processors to write reusable and extensible codes in CSS that are easy to maintain to increase productivity and reduce the amount of coding work that needs to be devoted to that part of a project.

Candidates who score well on this test have a strong grasp of CSS and its associated techniques, tools, and principles to create appealing web properties. They can fix bugs that arise on the front-end during development and implement a design without using unnecessarily complex code.

Why CSS is important

CSS stands for Cascading Style Sheets, and it enables web developers to define the style of a website or a web application. With CSS, developers can create beautiful and appealing products for end-users – in other words, your website’s visitors.

However, it’s not easy to find developers who have practical skills and in-depth knowledge of CSS. You need experienced software developers who can write clean, readable, and concise code that translates well into a web application or website.

To ensure that you hire the right candidate during your hiring process, you should use a pre-employment assessment tool like TestGorilla’s CSS pre-employment test. The test will evaluate your candidates’ basic and advanced CSS knowledge, including their ability to understand properties, use preprocessors, and write scalable code that is reusable and extensible.

Candidates who score well on the pre-employment test have strong CSS skills and are able to create appealing styles for web pages. These candidates also have the skills to solve and fix bugs that might appear while developing the front-end of websites and to use simple solutions without writing unnecessarily complex code.

CSS competencies for candidates

A web developer needs the following skills:

• HTML: CSS is often paired with HTML, so you will frequently see job ads for web developer roles that require both HTML and CSS skills. Although HTML and CSS have their own unique markup (code) and uses, CSS is often used to add style and responsiveness to HTML pages. This means it is useful to understand how a browser would use HTML and how CSS will contribute to web page display.

• Analytical skills: Good web developers also have keen analytical skills. Since they need to create successful websites, they have to ensure that the code they write is correct and functional.

An understanding of UI/UX: A good CSS coder knows that they’re not creating the website for themselves, but rather for other people. Having an understanding of user experience and user interfaces will help the developer create a layout that puts the end-user first.

• JavaScript skills: It’s almost impossible to talk about coding websites (for both mobile and desktop) without mentioning the JavaScript programming language. This tool implements moving elements on websites, such as search bars, videos, and maps. A web developer needs to have at least a basic understanding of JavaScript.

• Debugging skills: Great web developers constantly test their web pages to see if they have any bugs. If they find an issue, they should know how to debug it and fix the section of the website that’s bugging or malfunctioning. A good web developer knows how to perform both functional testing and unit testing.

Other skills candidates should have

On top of technical skills, the right candidate also needs to be a positive culture-add for the team and your organization. Their values should align with those of the company, and they need to have a set of soft skills that makes them invaluable in the workplace. Top web developers have the following skills:

• Time-management: The right candidate knows how to manage their time and meet project deadlines. Most programmers are detail-oriented and want their code to be perfect, but they need to work efficiently and can’t ignore timelines and deadlines.

• Responsiveness to feedback: Web developers have to handle a lot of back-and-forth communication when working on a project. The candidate you hire will work with multiple people across different teams, so they will need to be responsive to feedback.

• Attention to detail: Bugs and problems often occur during the development stages (coding sessions). It’s critical for web developers to double-check their code and determine whether they have missed anything that might create a problem down the line, like a bug that wasn’t spotted.

• Problem-solving skills: It’s essential for web developers to have a solution-oriented mindset and look at a problem from different angles until they find a solution.

• Empathy: Last but not least, developers need to have empathy. They need to create websites or web applications that others can easily use. This requires developers to put themselves in the shoes of others who might not have the skill set they possess.

How can a CSS test help you hire?

There are three ways in which a CSS test can help you hire the right web developer:

When you use a CSS test as part of your recruitment process, you eliminate bias from the hiring process. By giving every candidate the test, you offer all of them the opportunity to show their skills.

Every candidate will get the same test, and you will receive quantifiable results in the form of numbers. The process is objective and enables you to easily compare candidates to see who did better on the test.

Pre-employment testing eliminates the need for CVs. With pre-employment testing, you can evaluate job applicants on hard and soft skills, and focus on the prospects who are best suited to the job.

In summary

When you include a CSS test in your hiring process, you may uncover individuals who are capable of using more advanced capabilities with more proficiency. TestGorilla’s CSS test will help you hire the best candidate to create and maintain high-quality websites and web applications for your customers.

Furthermore, TestGorilla's pre-employment evaluations assist you in determining which individuals are the best fit for the job and the company. You can identify the perfect fit for personality and culture while also assessing their technical ability by using further tests to analyze candidates' soft skills.

With TestGorilla’s pre-employment assessments you can make your hiring process simple, objective, and bias-free.


What is the difference between an assessment and a test?
An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.
Can I add my own questions to an assessment?
Yes! Custom questions are great for testing candidates in your own unique way. We support the following question types: video, multiple-choice, coding, file upload, and essay. Besides adding your own custom questions, you can also create your own tests.
How do video questions work?
A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now." You can learn more about video questions here.
Can you explain how the other custom question types work?
Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
Can I customize an assessment with my company logo and color theme?
Yes! You can add your own logo and company color theme to your assessments. This is a great way to leave a positive and lasting brand impression on your candidates.
What type of support do you offer?

Where in my recruitment process should I use the CSS test?
We recommend using our assessment software as a pre-screening tool at the beginning of your recruitment process. You can add a link to the assessment in your job post or directly invite candidates by email. TestGorilla replaces traditional CV screening with a much more reliable and efficient process, designed to find the most skilled candidates earlier and faster.
