Frontend Developer
Front-end development focuses on building the visual, interactive parts of a website that users see and interact with directly in their web browsers. This involves using three core technologies: HTML for content structure, CSS for visual styling and layout, and JavaScript for dynamic behavior and logic. Modern front-end development heavily relies on frameworks like React, Vue, or Angular to create complex, efficient user interfaces. A critical skill is implementing responsive design, which uses fluid grids, flexible images, and CSS media queries to ensure websites function perfectly and provide an optimal viewing experience across all devices, from mobile phones to desktop monitors. This also encompasses web performance optimization, accessibility standards, and cross-browser compatibility.

Reviewing core CLI skills, this article teaches how cd moves through the filesystem (home shortcuts, ..), ls lists and inspects contents (-l, -a, -R, paths), and mkdir creates folders (including -p), then ties them together in a quick project-setup workflow (cd to Projects, ls to verify, mkdir and enter a new dir). Mastering these basics speeds navigation, boosts productivity, and underpins more advanced tools.
