Front-end developers should know HTML5 and CSS3-which have been the standard versions for a while now-and know when to use their more recent features. These are the standard building blocks that web browsers interpret and present as visual UI elements. All front-end developers have to understand web markup (HTML) and cascading style sheets (CSS). For this category of web applications, front-end developers need to know: Such sites are still made of web pages that can contain animations and many graphic elements, but there is far less (custom) JavaScript normally involved. The simpler and older of the two styles, this is used in apps like Gmail’s “Basic HTML” version and in most traditional web forums. So how can you know what’s important when it comes to hiring front-end developers?īased on the project and what kind of user interface you want to provide, we can split up the front-end development skill set into two main areas: UI and front-end JavaScript. The general knowledge and skill set has also broadened, with many technologies being used across specializations. Within that, there are many more specific specializations, and new ones are appearing all the time. It’s used in multiple programming paradigms and represents its own specialization of front-end development, separate from HTML and CSS. At that point, JavaScript represented a set of basic functions for real-time web page modifications, allowing for animating UI elements and making them more interactive.īut now JavaScript, development is more complex. They have also spread to new contexts, like mobile, wearables, and cars.įront-end developers once easily mastered the three main technologies: HTML, CSS, and JavaScript. Over time, web user interfaces (UIs) have become more interactive. If we want to provide an engaging experience to our users, hiring good front-end developers is key. (In most cases, front-end development refers particularly to web applications as interpreted by a user’s browser.) Front-end developers are responsible for building the parts of applications that users see and interact with.
