A front-end developer is a web developer that codes the front end of a website. While web design is the way a website looks, front end development is how that design actually gets implemented on the web.

 

The pages of the internet are a sum of layers—structure, data, design, content, and functionality. The web would be a dust bowl of HTML and "Under Construction" GIFs without front-end developers taking the backend data and creating a user-facing functionality. By integrating markup languages, design, scripts and frameworks, front-end developers create the environment for everything that users see, click, and touch.
