HTML, CSS, and Javascript for Web Developers vs CSS Grid and Flexbox, v2
Same Bayesian formula, same rubric — so the difference in scores reflects the difference in the courses, not the difference in how we evaluated them.

CSS Grid and Flexbox, v2
Per-criterion
Genuinely rigorous on fundamentals — the CSS box model, positioning, the float-based layout era and JavaScript objects are taught with unusual depth for a free-to-audit course. The recurring drag is age: the front-end project leans on Bootstrap 3 (2013), and CSS Grid, Flexbox and modern JavaScript syntax barely appear, which reviewers flag constantly.
Yaakov Chaikin is the standout. Reviewers across every sample describe him as clear, rigorous and genuinely good at making mechanisms click rather than hand-waving them. The minority complaint is that he "walks you through steps" without always stopping to explain why, which leaves a thin slice of beginners feeling lost when an assignment diverges.
A university-branded front-end course you can audit for free, or take for the Coursera certificate at ~$49/month with a 7-day trial — most learners finish a single course in 4-6 weeks. For the depth of the HTML/CSS/JS fundamentals delivered, the price-to-content ratio is one of the strongest in this niche.
The capstone is a real, responsive restaurant/coffee-shop website built from scratch and deployed — a tangible portfolio artefact, and the most-praised structural element of the course. It loses points only because the project is built on Bootstrap 3, so the layout techniques you practise are no longer the current way the industry builds responsive sites.
The HTML, CSS and JavaScript fundamentals transfer directly and will outlast any framework. But the specific tooling — Bootstrap 3 grid, float layouts, XMLHttpRequest-style Ajax — is dated enough that learners must pair the course with a modern Flexbox/Grid and ES6 follow-up before the skills map cleanly onto 2026 front-end work.
Covers responsive layout across two parts — Flexbox (grid systems, navigation, responsive images) and CSS Grid (Mondrian and magazine layouts, cards). Reviewers say it teaches modern layout "without hacks", though v2 predates subgrid and container queries.
Jen Kramer is the most-praised element — a long-time CSS educator who explains layout clearly and at a beginner-friendly pace. Learners and a Hacker News commenter call her CSS courses "very good" and her teaching "well taught, in-depth".
Requires a $39/month (or $390/year) Frontend Masters subscription rather than a one-time purchase — strong value if you use the wider catalog, weaker if you only want this one course. The course is included in the standard subscription.
More hands-on than most CSS courses: each section ends in build exercises and a capstone, including a Mondrian painting and magazine layouts. The builds are small practice pieces rather than a full portfolio site, but they reinforce the concepts well.
Flexbox and Grid are the everyday tools for production layout, and learners report finishing real site layouts noticeably faster afterward. The main gap is currency — the newer features (subgrid, container queries) are covered in Kramer's v3, not this version.
