CSS interview questions and tests

CSS is a style sheet language designed to describe the appearance of a document created using a markup language, for example, HTML, XHTML or other XML-based languages. Using our CSS interview questions and tests you can verify the skills of web designers and web programmers, regardless of the preferred programming language (PHP, Perl, Java).

The level of questions of DevSkiller CSS interview questions and programming tasks varies from Junior to Senior. In order to pass all the questions and tasks, your candidate has to have the knowledge of some markup language, for example, HTML (HyperText Markup Language) and the basics of developing applications for the web.

What to look for in a CSS developer

CSS (Cascading Style Sheets) provides a standard definition for how elements on a page appear. This allows developers to define a standard look on a page so that whenever they create a new element, all of the same design standards remain intact. This means that new elements like colors and fonts, will be consistent across the page. CSS and HTML together make up much of the bulk of the World Wide Web, so your developer needs to know more than just the basic CSS skills.

The basics of CSS are actually quite simple, but some areas require extra effort. For instance, basic coding in CSS is easy, but it can be time-consuming, so frameworks are in place to speed up the process. Your CSS developer will need to have a good knowledge of these frameworks. The most popular Frameworks are Bootstrap (v4) and Foundation (latest version 6).

Your candidate should also be up to date with the latest version of CSS and should be aware of the modules and new selectors introduced in CSS 3.

It is vital that your CSS developer is knowledgeable when it comes to various aspects of the front end tech stack, other than the frameworks listed above. This includes knowledge of the CSS preprocessors, tooling, and CSS animations. It will also be beneficial if they can tell you a little about the CSS Flexbox model, CSS grid, and CSS Box model, all varying components that make up the knowledge of any good CSS developer.

Like what you see but want more?

It is perfectly acceptable to think that DevSkiller CSS interview questions sound great, but to still want to get more out of them. Maybe you want to test your applicants with your own custom made CSS interview questions? No problem.

The DevSkiller online task wizard comes prepared with default settings and ready to take CSS  CSS interview questions, but you can also build your own customizable tests. This option allows you to take DevSkiller testing further. You can choose the languages you assess, allocate a specific time limit, and even set the difficulty level of each question about CSS.

Want proof that CSS interview questions work?

It can be nerve-wracking deciding the best way to invest your company’s money, after all, investment in our screening tool is a big decision for every business. If you’re still unsure, read what some of our customers have to say:

Julien Gauthiez - Responsabile acquisizione talenti EMEA presso Criteo

"Utilizziamo DevSkiller in 15 sedi nelle nostre 3 regioni (USA/APAC/EMEA).

Richard Williams - Vicepresidente di ingegneria presso Plutora

"Grazie all'automazione della fase di screening, siamo riusciti a ridurre il tasso di colloqui di 50%. Allo stesso tempo, la qualità dei candidati che arrivano alla fase di colloquio è ora molto più elevata.

Magdalena Rogóż – Deputy Marketing Manager at Kodilla

“Using DevSkiller to grade tests is 2 times more cost-efficient while giving our students a much better test and preparing them for future recruitment tests.”

Domande frequenti

Do I need to be a programmer to use DevSkiller CSS interview questions?

Devskiller CSS interview questions are deliberately designed to be as simple to use as possible. Our aim is for non-technical recruiters to be able to efficiently hire developers to fill even the most experienced developer positions. Our CSS interview questions are prepared by our experts to allow non-technical users to send out tests and verify the CSS skills of candidates of any level of expertise.

Cosa si fa contro il plagio?

At DevSkiller we take plagiarism seriously and take every precaution to make sure the results of our CSS interview questions are trustworthy. We implement a number of tools to assess candidates for cheating, including screen recording and a range of social listening tools. Our automatic plagiarism detector also checks the code a candidate has entered against previous answers in our database and if there is a match, it is because the candidate has cheated.

What do candidates think of our CSS interview questions?

At DevSkiller the feedback we receive from developer candidates for our online tests is overwhelmingly positive. Candidates love the structure of our tests and like that they are being given a chance to prove their actual CSS skills, rather than simply being tested on algorithms. Occasionally candidates can be a little apprehensive at first, but this is usually because they have taken academic algorithmic tests in the past, that don’t test the skills they use day to day and they expect DevSkiller testing to be similar. Once they realize the difference, they relish having the opportunity to show what they can do.

What’s the test duration?

The duration of each CSS test depends on your preferences. DevSkiller testing comes with in-built default settings, or if you prefer you customize your tests and set your own test duration. It is also possible to set time limits for individual questions within the tests themselves.
