When we talk about "front-end," we're referring to the part of a website or application that displays on the screen, the part with which internet users and users directly interact. It's different from the back end, which concerns the invisible part of the site. As for front-end elements, they are composed of HTML, JavaScript, and CSS. HTML development and design are the two main skill areas of the front end. Design falls under the web designer's domain, and as for development, that's handled by the front-end developer. The designer creates graphic mockups with specialized software tools such as Photoshop, and it's up to the front-end developer to translate the graphic mockup into a functional mockup by manipulating code. In simple terms, the web designer draws, the developer formalizes using programming languages like HTML and CSS. Some developers are capable of working with JavaScript. But most of the time, the developer uses their preferred software for all their projects. Previously, development was limited to the back end. But today, more and more designers are starting to take an interest in development. The front-end developer often comes from a web design background.
