Course Overview

The Microsoft HTML5 Application Development Fundamentals course is designed for aspiring developers seeking to validate core skills in building client applications for modern touch-enabled devices such as PCs, tablets, and smartphones. This training aligns with the Microsoft Technology Associate (MTA) certification exam 98-375, which, although retired for certification purposes, remains a foundational benchmark for HTML5, CSS3, and JavaScript proficiency. Ideal for entry-level web developers, front-end developers, and software development students, this course equips learners with essential skills recognized across the tech industry. With over 214,900 web developer jobs in the U.S. alone and a projected 7% growth through 2034—much faster than average—mastering these core technologies provides a critical entry point into a high-demand field.

Participants in the HTML5 Application Development Fundamentals program engage with key technologies including HTML5 semantic markup, CSS3 for styling and layout, JavaScript for dynamic functionality, and advanced APIs such as Geolocation, Web Workers, and Web Sockets. The hands-on lab component is conducted in a browser-based development environment, where students build responsive user interfaces, implement animations, manage application state, and integrate device capabilities like touch gestures and local data storage. A key project involves developing a complete touch-enabled client application that demonstrates proficiency in UI construction, CSS positioning, and JavaScript event handling—mirroring real-world development scenarios. These practical exercises ensure learners gain experience with the tools and workflows used by professional web developers.

This course prepares learners for the MTA: HTML5 Application Development Fundamentals certification, a respected credential that validates foundational web development skills and serves as a stepping stone to advanced Microsoft certifications. Web developers with these competencies earn a median annual salary of $95,380 in the U.S., with front-end developers commanding starting salaries up to $104,750, according to Robert Half’s 2025 Salary Guide. Koenig Solutions enhances this learning path with its Guaranteed-to-Run promise, ensuring every scheduled batch proceeds regardless of enrollment, along with access to official Microsoft courseware and 1-on-1 training options for personalized learning. Completing this program empowers individuals to launch careers in web development, where they can design, build, and maintain the next generation of interactive, cross-device applications.

Is the HTML5 Application Development Fundamentals certification exam fee included in the Koenig training course, and what is the cost if separate?
The HTML5 Application Development Fundamentals exam (98-375) is retired and no longer available for purchase. As this is a legacy course, we recommend transitioning to current Microsoft Learn paths such as AZ-204 (Developing Solutions for Microsoft Azure) or PL-400 (Microsoft Power Platform Developer) to earn active, industry-recognized certifications.
What training formats does Koenig offer for HTML5 Application Development Fundamentals, and is Guaranteed-to-Run scheduling available?
Koenig provides legacy training for HTML5 Application Development Fundamentals via live online, classroom, 1-on-1, and self-paced Flexi formats. All options are Guaranteed-to-Run. We encourage students to leverage these foundational skills as a bridge toward modern Microsoft certification paths like AZ-204 or PL-400.
How long is lab access provided after completing the course, and what type of lab environment is used?
Koenig grants 30 days of post-training lab access through our LET Platform. You will use cloud-based, secure sandboxes to practice HTML5, CSS3, and JavaScript. These environments are designed to build the core web development skills required for advanced Microsoft cloud and application development certifications.
What is Koenig's rescheduling and cancellation policy for the HTML5 Application Development Fundamentals course?
Koenig permits one free reschedule if requested over 10 days before your start date. Cancellations or changes within 10 days incur a 50% fee of the total price. To ensure scheduling stability for all learners, the same session cannot be rescheduled more than once under our Terms of Service.
What is the format, number of questions, passing score, and time limit for the HTML5 Application Development Fundamentals exam?
The HTML5 Application Development Fundamentals exam (98-375) was retired by Microsoft on June 30, 2022. It is no longer possible to sit for this exam. Candidates looking to validate their skills should now focus on current Microsoft certification exams, which align with modern cloud and application development standards.
How long is the HTML5 Application Development Fundamentals certification valid, and what is the renewal process?
The MTA: HTML5 Application Development Fundamentals certification is a legacy credential that is no longer being issued. Because the exam was retired on June 30, 2022, there is no renewal process. We advise professionals to pursue current Microsoft certifications, such as AZ-204, which reflect the latest industry requirements.
What post-training support does Koenig provide after completing the HTML5 Application Development Fundamentals course?
Koenig provides 30 days of post-training support, including session recordings, expert instructor guidance, and continued lab access.

What prerequisites or prior experience are recommended for the HTML5 Application Development Fundamentals course?
We recommend foundational knowledge of HTML, CSS, and JavaScript, plus basic web browser familiarity. This course serves as a legacy introduction to web development. For those seeking career advancement, we recommend following this with training for current Microsoft certifications like AZ-204 or PL-400.
What is the average salary for professionals with HTML5 and Microsoft certification skills?
According to Glassdoor 2023 data, web developers earn an average of $81,723 annually in the U.S. Professionals holding current, active Microsoft certifications often report higher earning potential and increased job security compared to those relying on retired or legacy credentials.
How does formal training for HTML5 Application Development Fundamentals compare to self-study in terms of effectiveness and preparation time?
Formal training provides structured, instructor-led learning with labs, usually completed in 3–5 days. While this course provides a strong conceptual foundation, we recommend supplementing it with current Microsoft Learn modules to prepare for modern, active certification exams that are highly valued by employers.
