Web Development Mastery: HTML, CSS & JavaScript Fundamentals is a beginner-friendly path into front-end development. It starts with how websites are built and what makes a good user interface, then moves through the languages and frameworks that professional front-end developers use every day.

By the end, you can build responsive sites with semantic HTML5, CSS and JavaScript, lay out pages with Flexbox and Bootstrap, and create interactive React components with state - across 24 short video lessons, 8 readings and 11 assignments.

It's course 1 of Board Infinity's Full-Stack Web Development: PHP, HTML, CSS & JavaScript specialization on Coursera - the front-end foundation for the back-end courses that follow.

08 FAQ

Common questions

Everything learners ask before enrolling, answered plainly.

About the course

Module one covers how web development works, front end versus back end, the tools developers use, UI design principles and patterns, and HTML and CSS basics. Module two covers semantic HTML, forms and input types, HTML5 elements, CSS Flexbox and Bootstrap. Module three covers JavaScript fundamentals, DOM manipulation, ES6, asynchronous JavaScript, and React components, props and state.

No. Coursera lists this as a beginner-level course, and it starts with what web development is and how websites are built. It's the first course of the specialization, so it's the natural place to start.

The current enrollment options and price for your region are shown on the Coursera course page. The course is included with a Coursera Plus subscription, and Coursera's financial aid is available for eligible learners. Enrollment also includes the whole Full-Stack Web Development specialization track.

About 16 hours of total learning across 3 modules of roughly 6, 4 and 6 hours, with 24 video lessons, 8 readings and 11 assignments. Coursera estimates 2 weeks at 10 hours a week. It's fully self-paced - deadlines flex around your schedule.

Each module has practice quizzes for its lessons and a one-hour graded quiz at the end - 11 assignments in all. Readings go further into topics like UI design, advanced HTML, CSS frameworks and front-end frameworks, and two discussions let you compare notes with other learners.

Yes - this page is Board Infinity's own overview of our course. Enrollment, payment, video lessons, grading and the certificate all happen on Coursera, where the course is hosted. Think of this page as the detailed tour before you head there.

Career & certificate

Yes. Completing the graded quizzes earns you a shareable certificate from Board Infinity, issued through Coursera with its own verification link. You can add it to your LinkedIn profile, resume or CV, and the same completed work counts toward the full specialization certificate.

It supports front-end developer, web developer, UI developer and junior React developer roles, and it's the foundation for full-stack roles once you add the back-end courses in the specialization.

Two ways. The certificate goes in your LinkedIn Licenses & Certifications section via Coursera's one-click add. Just as valuable is naming what you can do: a line like “Built responsive pages with semantic HTML5, Flexbox and Bootstrap; added interactivity with JavaScript and React components” gives interviewers something concrete to ask about.

Yes. Module three introduces React after the JavaScript fundamentals, covering components and props and state management.

This is the first course of the specialization. Next come Backend Development: Node.js, Express, MongoDB & REST APIs (~13 hours) and PHP Mastery: Build Web Apps (~11 hours). Completing all three earns the specialization certificate.
