Teaching responsive layout fundamentals to freelancers across Asia-Pacific
Who’s Behind LayoutMaster
Marcus discovered web design in 2010 while freelancing part-time during university at CityU. He quickly realized most designers struggled with responsive fundamentals rather than visual creativity. After five years as a frontend developer at digital agencies in Central, he transitioned to full-time education in 2015 — frustrated by the gap between what freelancers were taught and what clients actually demanded.
His breakthrough came in 2017 when he developed a CSS Grid-based curriculum specifically for Hong Kong’s mobile-first market. The results spoke for themselves: 94% student completion rates compared to industry averages of 60%. Since joining LayoutMaster Hong Kong Limited in 2018, Marcus combines real-world client experience with his teaching methodology, regularly updating courses based on feedback from mentees working in local agencies like Pixel & Pencil and Beanstalk Digital.
He’s driven by the belief that strong technical foundations shouldn’t be boring. Over the past eight years, Marcus has trained more than 2,500 freelancers and small agencies. He’s written over 80 technical articles on responsive design patterns used in production environments, and he speaks regularly at design meetups across Hong Kong and Singapore.

What Marcus Teaches
Practical responsive design skills for real-world projects
Flexible Grids & Breakpoints
Understanding how to build grids that work on every screen size. We cover fluid typography, relative sizing, and the viewport meta tag that most freelancers get wrong.
Mobile-First Approach
Building for mobile first, then progressively enhancing for larger screens. This isn’t just theory — it’s how modern clients expect their sites to work. We’ll dive into CSS media queries and container queries.
Flexbox & Grid Mastery
When to use Flexbox, when to use Grid, and when to combine them. We’ll build real layouts from client briefs, not theoretical examples. You’ll see how major sites actually structure their layouts.
Cross-Device Testing
Testing on actual devices, not just browser DevTools. We’ll cover real testing workflows, debugging responsive issues, and performance optimization for slower connections in Southeast Asia.
Production-Ready Code
Writing CSS that clients and future developers can actually maintain. We focus on naming conventions, organization, and avoiding the common pitfalls that make codebases messy.
Accessibility Standards
WCAG compliance and inclusive design principles. Responsive design without accessibility is just half the job. We’ll ensure your layouts work for everyone, including users with screen readers.
“Most freelancers think responsive design is about making things smaller on mobile. It’s not. It’s about fundamentally rethinking how content flows, how space is distributed, and how users interact with your site at different scales. Get that right, and everything else becomes easier.”
