How to screen front end developer skills - HTML and CSS Blog

Wie man die Fähigkeiten von Frontend-Entwicklern prüft - HTML und CSS

Durch Kodierungstest, Front-End-Entwickler, Fragen zum Interview, IT-Rekrutierung

HTML and CSS are two of the most fundamental front end developer skills. You’d be hard-pressed to come across a web developer who doesn’t have at least a basic understanding of the two stalwarts. However, some believe that HTML and CSS shouldn’t be given the same respect as other languages because neither requires any internal logic. That’s because HTML and CSS are declarative languages that instruct a web browser to render web pages rather than use computational code.

Despite what some may think, it’s becoming increasingly valuable for developers to possess in-depth knowledge and expertise of theses two languages. Verifying a developer’s HTML and CSS skills is as important as ascertaining skills in languages like Java and C++. Surely, anyone vaguely technical should have a basic understanding of HTML and CSS. In the end, that’s all you need, right? Not exactly.

HTML and CSS make up the backbone of front end development along with JavaScript. In fact, you’ll also find quite a lot of back-end developers who use these languages on a regular basis. While you will never find a developer who solely uses these languages, HTML and CSS are critical enough to modern software development to ensure that front end developers are able to use them effectively. While they are simple to get started with, advanced applications require in-depth skill and understanding. It’s essential to verify that your developer has this understanding.
