Front-end development involves building the elements of a website that users interact with directly. This document provides an overview of HTML, CSS, semantic markup, responsive design, and tools for front-end development. It defines HTML as the standard markup language for web pages and CSS as the style sheet language used to describe document formatting. Semantic HTML uses meaningful markup to reinforce content semantics rather than just presentation. Responsive design approaches like separate files or media queries allow content to adapt to different devices. Development tools like Chrome DevTools, WebStorm IDE, and Grunt help automate tasks.
