In plain English

This repository holds all the example source code written during the Coursera course called HTML, CSS and Javascript for Web Developers, offered by Johns Hopkins University. The course is free to enroll in, and the code here is a companion resource for anyone taking it or reviewing what was covered. HTML, CSS, and JavaScript are the three foundational languages of the web. HTML defines the structure of a page (headings, paragraphs, links, images), CSS controls how it looks (colors, layout, fonts), and JavaScript adds interactivity (buttons that do things, forms that respond, content that updates without reloading). Together they are the starting point for almost all website work. The repository contains the code examples from each part of the course, organized so learners can follow along or look back at specific lessons. A separate FAQ file answers common questions that have come up in the course forums, which can help if something in the material is unclear. One notable piece of the course is that students built a real website for an actual restaurant, David Chu's China Bistro in Baltimore, Maryland. The README notes the site was left without speed optimizations on purpose, since that topic was outside the course scope. This gives learners a concrete, finished example of what the course material produces when applied to a real project rather than a toy exercise. With nearly 11,000 GitHub stars, this is one of the more widely referenced course repositories on the platform. It is suited for complete beginners with no prior web development experience, and the Coursera course itself is the primary context for using it.
