This document provides an overview of front end development. It defines front end development as the mix of programming and layout that powers website visuals and interactions. The three main front end tools are HTML, CSS, and JavaScript. HTML describes page structure and content, CSS describes appearance, and JavaScript transforms static pages into dynamic interfaces. Front end development is like the user interface of a car - it's what users directly see and interact with. Understanding front end is important for developers because it provides the appearance and functionality of a website without which the backend is useless. The document provides simple code examples and references to introduce front end concepts.
