As part of my ongoing exploration of responsive design, I set out to understand how a card-based UI component could adapt fluidly across a range of screen sizes and resolutions. This wasn't just about making things look good at different breakpoints — it was an exercise in observing how content hierarchy, alignment, and spacing respond as the layout stretches, stacks, or compresses. By building and testing the UI card component, I aimed to get a hands-on grasp of the design decisions that make flexible interfaces work across devices.
Flexible Fit: The Knickerbocker Way
Curious about how this type of graphic would adapt across various screen sizes, I decided to explore its responsiveness as a design exercise. Although originally intended for broadcast or social media use, typically viewed on standard television, I wanted to test how the layout behaves when stretched across wider desktop displays or compressed into smaller, narrower frames. This led me to consider how elements like the logo placement, typography scale, and spacing might shift to maintain clarity and visual balance. My goal wasn't to redesign the card, but rather to understand how a static piece of sports media content could be reimagined with responsiveness in mind, without losing its strong visual identity or immediate readability.
Fluid Card Layout Using CSS Grid, Flexbox & Media Queries
I built the layout using only HTML and CSS, focusing on simplicity and performance. My first step was to structure the HTML in a way that would support flexible behavior from the start, using a layout that could easily adapt to shifts in screen size without breaking the visual hierarchy.
To keep the layout compact and readable on large screens, I set a max-width of 900px on the main container, ensuring that the content wouldn't stretch too wide on desktops. I used CSS Grid to define the structure, applying semantic grid names like header, logo, and content to make the layout logic easy to follow and maintain. The grid setup consisted of two rows and two columns, giving me a flexible base to arrange elements while keeping the established visual hierarchy.
Further on, I assigned the semantic grid areas to the corresponding elements, ensuring each part of the layout landed exactly where intended. Inside the main content area, I used Flexbox to arrange the list of upcoming fixtures.
Next, I introduced a media query targeting screens narrower than 768px to make the layout more mobile-friendly. In this view, the grid collapses into a single column by redefining the template with grid-template-columns: 1fr; and stacking the areas vertically as header, logo, and content. I used font-size: clamp(16px, 3.5vw, 30px); to make the text scalable, and centered it, to improve readability and visual balance on smaller screens. This adjustment ensured the layout remained clear and accessible without compromising its structure.
clamp()This final step allowed me to achieve the responsive behavior I was aiming for — preserving the structure and clarity of the design while adapting smoothly to smaller screen sizes. By combining CSS Grid, semantic grid names, and a simple media query, the layout remained visually coherent across a range of devices without requiring complex adjustments.
The live prototype is on CodePen:
Pushing the design to work on not just wide, but very narrow screens turned out to be both fun and revealing. It forced me to rethink how layout, spacing, and content hierarchy behave when there's barely any room to breathe. This wasn't just a responsive design exercise — it was a way to test how far a single card component could stretch (or shrink) while still feeling balanced and usable.
