[DotJs2024] API Design is UI Design
In the intricate tapestry of software craftsmanship, the boundaries between visual interfaces and programmatic ones blur, revealing a unified discipline rooted in empathy and usability. Lea Verou, a luminary in web standards and W3C TAG member, delivered a revelatory session at dotJS 2024, asserting that API design mirrors UI design in every facet—from intuitiveness to error resilience. With a PhD from MIT focused on developer experience and stewardship of dozens of open-source projects, Verou dissected the pitfalls of APIs that frustrate and the principles that enchant, urging creators to treat code as an interface wielded by fellow humans.
Verou opened with a visceral anecdote: the SVG DOM’s labyrinthine quest to extract a circle’s radius, yielding not a crisp number but an SVGAnimatedLength
riddled with baseVal, animVal, and unit-conversion methods—annoying even sans animations. This exemplar encapsulated her thesis: APIs, be they functions, classes, components, or native browser APIs, are user interfaces where developers are the users, and interactions manifest as keystrokes. Echoing Alan Kay’s maxim—”simple things should be easy, complex things possible”—she mapped it to a complexity plane: low-effort dots for trivial tasks, viable paths for sophistication. Usability tenets, from Google Calendar’s drag-and-drop simplicity to advanced recurrence rules, permeate both realms; DX is merely UX recast for code scribes.
Central to Verou’s discourse was user-centricity: APIs thrive when attuned to genuine needs, not theoretical purity. High-level use cases—like assembling IKEA furniture with a screwdriver—inform broad abstractions, while low-level ones—like screwing a wall anchor—demand primitives. She critiqued legacy DOM traversals burdened by redundant parent references, supplanted by modern APIs favoring single-truth sources. Components exemplify elegance: encapsulating dialog boilerplate into reusable units slashes cognitive load. Iterating isn’t prohibitive; ship high-level facades covering 80% of scenarios, layering primitives as demands surface—or vice versa, observing usage to scaffold abstractions. The Intl.DateTimeFormat API’s evolution—from vague toLocaleString to nuanced options yielding structured outputs—exemplifies this progressive disclosure, smoothing from casual to granular control.
Verou championed empirical validation: user testing, sans visuals, via representative tasks and think-aloud protocols. Five participants unearth 85% of issues; two halve them. Zoom suffices—no labs required. Dogfooding complements: prototype demos, draft docs, author tests pre-implementation, refining iteratively. Empathy crowns all: intuit users’ pains, infer principles organically. Tailwind’s rise signals CSS’s accessibility gaps; blame the medium, not the maker, and mend it. Verou’s clarion call: infuse humanity into APIs, easing burdens and amplifying creativity across the dev spectrum.
Usability Principles Across Interfaces
Verou wove Kay’s dictum into a visual quadrant, plotting task complexity against UI/API effort, advocating coverage of simple-easy and complex-possible quadrants. User needs—pain points, scenarios—drive this: distinguish macro goals from micro actions, ensuring APIs mirror real workflows. SVG’s unit obsessions ignored 90% of queries; streamlined getters would suffice. Progressive layers, as in date formatting’s escalating options, democratize power without overwhelming novices.
Empirical Refinement and Empathy
Testing APIs demands observation: task users, query struggles non-leadingly, affirm it’s the design under scrutiny. Verou debunked myths—engineers aren’t users; widespread misuse indicts the API. Dogfood rigorously: sketch code flows pre-build, iterate via docs and tests. Ultimate imperative: cultivate care—empathize with wielders’ contexts, yielding designs that intuit, adapt, and inspire.

[DotCSS2018] DotCSS 2018: Hugues Tennier – Essential Practices for Inclusive Web Experiences
Hugues Tennier, a dedicated advocate for equitable digital interfaces, delivered a succinct yet potent guide at DotCSS 2018 on elevating site usability through foundational accessibility tenets. With a focus on subtle yet seismic adjustments, he empowers creators to craft environments where diverse users thrive, from those with visual impairments to casual browsers under duress. Tennier’s framework underscores that inclusivity is not an addendum but the bedrock of resonant design.
Enhancing Visibility and Scalability
Tennier commences with color contrast, a linchpin for low-vision individuals or those navigating bright externalities. He recommends ratios surpassing WCAG benchmarks, verifiable via Chrome DevTools’ color picker—where hues above a stark threshold signal inaccessibility. This vigilance ensures content pierces veils of glare or haze, democratizing comprehension.
Pivotally, he champions resizable text, countering the fallacy of pixel-bound rigidity. Relative units like em or rem scale harmoniously with user preferences, accommodating 200% zooms sans distortion. A “Buy Now” button exemplifies: pixelated padding contracts uncomfortably at magnification, whereas rem fonts paired with em margins expand proportionally, preserving tap targets and legibility. Heights, too, warrant caution; fixed values invite overflow, but fluid metrics foster seamless growth.
These maneuvers, Tennier asserts, transcend compliance—they cultivate empathy, envisioning interfaces that adapt to life’s variances rather than impose uniformity.
Structuring Semantics and Interaction Clarity
Semantic HTML forms the next pillar, streamlining navigation for screen reader devotees via logical heading hierarchies. Sequential H1 through H6 milestones guide users briskly, averting disorientation amid skipped strata.
Visible focus indicators reclaim agency for keyboard navigators, whose tab traversals demand luminous cues. Dismissing default outlines is permissible, Tennier concedes, provided substitutes—vibrant borders or glows—affirm position without aesthetic compromise.
Finally, discerning links from buttons averts interpretive pitfalls: anchors herald navigational leaps, intoned as such by assistive tech, while buttons signal actions like submissions, primed for Enter or Space invocations. Divs, bereft of innate semantics, falter in announcements, underscoring the peril of repurposing for interactivity.
Tennier encapsulates these as duty-bound refinements—contrast, scalability, semantics, focus, and apt elements—that transmute exclusionary hurdles into welcoming pathways. In weaving accessibility into the warp and weft of creation, we honor the web’s inclusive ethos.

[DotCSS2018] DotCSS 2018: Aga Naplocha – Igniting Innovation Through Unconventional CSS
Aga Naplocha, a dynamic UX consultant and co-founder of The Awwwesomes, captivated the audience at DotCSS 2018 with her exploration of CSS as a canvas for audacious creativity. Frustrated by the monotony of grid-locked interfaces, she advocates for leveraging underutilized CSS features to infuse web projects with vitality and originality. Naplocha’s session serves as both a lament for stale aesthetics and a blueprint for reinvention, urging designers and developers alike to draw from diverse inspirations.
Rediscovering Inspiration Beyond Digital Echo Chambers
Naplocha opens with a personal anecdote of creative paralysis, where a routine assignment unearthed a profound dissatisfaction with ubiquitous layouts—endless columns and rectangles that stifle imagination. This epiphany, amplified by a satirical critique from 2015 decrying web design’s blandness, prompted her to unplug from online trend mills like Dribbble and Behance. Instead, she turned to analog sources: vintage magazines borrowed from a friend, whose eclectic collages and asymmetrical compositions rekindled her zeal.
This detour into print media revealed parallels to the web’s untapped potential, where content could dictate form rather than conform to it. Transitioning back online, Naplocha encountered brutalist websites—raw, rule-defying sites that prioritize uniqueness over polish. Exemplars like Bloomberg’s bold, GIF-laden articles demonstrate how even corporate entities can embrace eccentricity, blending vibrant hues and retro flair to elevate mundane narratives. She posits that such nonconformity, though occasionally UX-taxing, injects essential weirdness into the digital tapestry, challenging the hegemony of sanitized grids.
Furthermore, Naplocha emphasizes simplicity as the gateway to collaboration. By distilling complex visions into elemental CSS—eschewing heavy libraries—she bridges the chasm between novice designers and seasoned coders, democratizing innovation.
Harnessing CSS for Expressive, Nonconformist Layouts
Delving into technical territory, Naplocha unveils CSS clipping and masking as scissors for digital paper, enabling precise visibility control without raster dependencies. Clipping carves crisp, vector-based boundaries via paths or polygons, ideal for geometric precision, while masking modulates transparency pixel-by-pixel for gradient fades and layered illusions. She illustrates with a fixed-position header that unveils text through a scrolling mask, creating depth akin to overlapping transparencies—achievable with minimal code, yet profoundly impactful for prototyping.
Distinguishing the duo, Naplocha notes clipping’s efficiency for sharp edges versus masking’s computational heft for nuanced opacity. She extends this to shape-outside
, liberating text from rectangular tyranny by wrapping around custom contours, such as circular initials or polygonal SVGs. A caveat: floated elements require explicit dimensions for coordinate anchoring, and complementary clipping ensures silhouettes align seamlessly.
Naplocha ties these techniques to broader movements, like SVG filters for glitch artistry or variable fonts for fluid expressiveness. Her finale spotlights a pure-CSS perspective skew on architectural copy, crediting James Bosworth’s CodePen, and rallies for side projects as low-stakes proving grounds. From the Stedelijk Museum’s stark brutalism to a Parisian brutalist basketball court, she curates real-world muses, echoing Henri Matisse’s creed that “creativity takes courage.” In her view, CSS’s arsenal empowers us to architect wilder webs, fostering environments where experimentation trumps convention.

[DotCSS2018] DotCSS 2018: Dan Cederholm – Reflections on Two Decades with CSS
Dan Cederholm, a pioneering figure in web design and founder of SimpleBits, reflected deeply on his journey with CSS during his presentation at DotCSS 2018. Drawing from over two decades of experience, he shared lessons that extend far beyond syntax and selectors, touching on resilience, community, and the ephemeral nature of digital creation. Cederholm’s candid recounting of triumphs and setbacks offers timeless wisdom for developers navigating the ever-evolving landscape of web technologies.
Embracing Bold Steps and Community Sharing
Cederholm’s narrative begins in the early 2000s, a period marked by the shift from table-based layouts to CSS-driven designs. He vividly recalls the 2002 redesign of Wired News, a landmark project that propelled the industry forward by abandoning support for outdated browsers like Netscape 4. Inspired by Jeffrey Zeldman’s provocative article “To Hell with Bad Browsers,” Cederholm approached his then-employer, Fast Company magazine, with a proposal to follow suit. To his surprise, his forward-thinking boss greenlit the initiative, leading to a 2003 overhaul that, despite backlash from a shrinking cohort of legacy users, cemented Cederholm’s commitment to progressive standards.
This pivotal moment not only honed his technical skills but also ignited a passion for documentation and mentorship. While iterating on the Fast Company site, Cederholm chronicled his process on a rudimentary blog, despite lacking formal writing credentials. This habit of sharing raw, in-progress insights—complete with the era’s notorious browser bugs—fostered unexpected connections. Invitations to speak and collaborate followed, transforming personal experimentation into professional opportunities. Cederholm underscores a key takeaway: vulnerability in sharing imperfect knowledge builds bridges, turning solitary coding sessions into collaborative dialogues that propel collective advancement.
Moreover, these early risks taught him the value of persistence amid imperfection. The browser wars demanded ingenious workarounds, yet each hack refined his problem-solving acumen. Today, as frameworks proliferate, Cederholm urges newcomers to view challenges not as barriers but as catalysts for growth, reminding us that mastery emerges from repeated trial and adaptation.
Navigating Evolution and Impermanence
As the web matured, so did Cederholm’s toolkit, evolving from vanilla CSS to preprocessors like Sass. Initially resistant—citing concerns over code readability and the philosophy of keeping CSS accessible for novices—he eventually embraced Sass after a colleague’s pragmatic suggestion to simply rename files. This incremental adoption, starting with variables for vendor prefixes and nesting for media queries, revolutionized his responsive workflows. The experience with Sass, much like his initial foray into CSS, highlighted the pitfalls of premature dismissal; what begins as reluctance often blossoms into indispensable efficiency.
Cederholm also touches on broader philosophical shifts, such as his evolving stance on methodologies like Atomic CSS. Initially skeptical of utility class names, he came to appreciate their utility in rapid prototyping, especially within team environments. This openness stems from a core principle: prioritize tools that minimize code volume and maximize clarity. Yet, he tempers enthusiasm with caution, advocating for mindful integration rather than wholesale overhaul.
Ultimately, Cederholm’s reflections circle back to transience. In an industry where innovations cascade rapidly—rendering yesterday’s hacks obsolete—he finds solace in impermanence. Echoing the sentiment of his Adventure pin design, “Everything is stardust,” he posits that the pressure to master every novelty dissipates when viewed against the web’s fleeting canvas. This perspective liberates creators to experiment joyfully, unburdened by the fear of obsolescence. As he concludes, the true legacy of CSS lies not in enduring code but in the enduring habits of curiosity and camaraderie it instills.

[DotCSS2018] DotCSS 2018: Natalya Shelburne – CSS at the Intersection of Mental Models
Natalya Shelburne, a designer-turned-software-engineer, delivered a thought-provoking talk at DotCSS 2018, exploring CSS as a nexus of diverse mental models. Drawing from her experience as an educator and career switcher, Natalya examines why CSS sparks debates about its efficacy and ownership, advocating for tools that foster collaboration across disciplines.
The Clash of Mental Models
Natalya frames CSS as a battleground where designers and developers, shaped by distinct prior knowledge, encounter cognitive dissonance. A designer accustomed to global styling may find CSS’s cascade intuitive, while a programmer seeking control flow might view it as chaotic. This dissonance, while a natural part of learning, can lead to public frustrations that reinforce silos between job roles.
Natalya argues that these debates—whether CSS is “broken” or “awesome”—stem from the intersection of mental models. By embracing cognitive dissonance as a learning opportunity, developers and designers can grow beyond their comfort zones, fostering a more cohesive industry.
Building Collaborative Tools
To bridge the gap between design and development, Natalya advocates for tools like design systems and prototype environments. She shares an example from a project where a designer proficient in HTML/CSS but not JavaScript collaborated with a JavaScript-focused developer. By creating a style guide and a private prototype route, the team enabled the designer to contribute semantic HTML and CSS, which the developer then connected to data and abstractions. This approach minimized handoff gaps, allowing both team members to expand their skills.
Natalya’s Harvard Extension course further illustrates this philosophy. By assigning roles outside students’ expertise (e.g., a JavaScript developer designing UI), she created a safe space for experimentation, resulting in improved collaboration and skill growth. These tools and practices empower teams to transcend arbitrary barriers, enhancing productivity and creativity.
Embracing Flexibility for Growth
Natalya emphasizes that above-average learning requires deliberate flexibility. By challenging assumptions and embracing discomfort, individuals can become “unicorns”—professionals adept at multiple disciplines. This flexibility not only enhances personal growth but also enables the creation of inclusive tools that empower entire teams. Natalya’s call to action is clear: build interfaces that accommodate diverse mental models, fostering a collaborative and innovative web community.

[DotCSS2018] DotCSS 2018: Elika J. Etemad – A Primer on Web Internationalization
Elika J. Etemad, known as fantasai, is a seasoned expert in the CSS Working Group, with a deep focus on internationalization (i18n). At DotCSS 2018, Elika provided a concise yet comprehensive overview of how the web platform supports multiple languages and locales, offering practical guidance for developers to create globally accessible websites.
Language and Localization
Elika distinguishes between translation (converting text to another language) and localization (adapting content to cultural and regional norms). For example, a website operating in Canada and the US may not require translation but must account for differences in currency, dates, or marketing strategies. She emphasizes the importance of explicit language selection, allowing users to choose their preferred language regardless of their location. The lang
attribute in HTML is crucial, as it informs CSS about typographic nuances, such as hyphenation dictionaries or glyph shapes, that vary by language.
Elika also highlights the role of content negotiation, where browsers use language headers to signal user preferences. By adopting UTF-8 encoding universally, developers can ensure compatibility across all writing systems, simplifying the internationalization process.
Bidirectional Text and Layout
A significant challenge in i18n is handling bidirectional (bidi) text, particularly for right-to-left (RTL) languages like Arabic and Hebrew. Elika explains the Unicode Bidirectional Algorithm, which orders text logically rather than visually, ensuring correct display even when mixing scripts (e.g., Arabic names in an English sentence). The dir
attribute in HTML, not the CSS direction
property, is the correct tool for setting base directionality, as it creates isolated contexts for text rendering.
This bidirectionality extends to layout, affecting alignment, column ordering, and scrolling direction. Logical properties like margin-inline-start
and values like text-align: start
adapt dynamically to the writing direction, making layouts robust across languages. Elika’s insights underscore the importance of these tools in creating seamless, multilingual user experiences.
Sizing and Typography Considerations
Elika also addresses sizing challenges in multilingual design. Character density varies across languages—Chinese is compact, while French is verbose—impacting layout when fixed sizes are used. Intrinsic sizing, enabled by keywords like auto
, min-content
, and max-content
, allows layouts to adapt to content length. For instance, a poster design translated into Chinese retains its visual relationships when using intrinsic sizing, ensuring consistency across languages.
Typography also requires attention, as line spacing needs differ (e.g., Vietnamese requires more vertical space for accents). By leveraging CSS’s logical properties and language-based selectors, developers can tailor layouts to these nuances, enhancing readability and aesthetics.

[DotCSS2018] DotCSS 2018: David DeSandro – Decoding Color Hex Codes
David DeSandro, a colorblind designer and developer, shared a unique perspective at DotCSS 2018, unveiling his method for interpreting color hex codes. His talk transcends mere technical instruction, weaving together insights into human vision, computer history, and digital color theory. By breaking down the process of reading hex codes, David empowers developers to understand colors in a way that is both accessible and profound, particularly for those who cannot rely on visual perception alone.
The Mechanics of Hex Codes
David begins by demystifying the structure of hex codes, which are six-digit alphanumeric sequences representing RGB (Red, Green, Blue) values. Each pair of digits corresponds to one color channel, expressed in hexadecimal, a base-16 system using digits 0-9 and letters A-F. This system, rooted in computer history for its concise representation of binary data, is optimized for machines but less intuitive for humans. David’s approach simplifies this by focusing on the relative values of each digit—0 being the lowest, F the highest.
To make hex codes more digestible, David advocates for the three-digit shorthand (e.g., #D92
instead of #DD9922
). This shorthand, achieved by duplicating each digit, approximates the original color while being easier to parse. For example, #D92
translates to high red, medium green, and low blue, providing a quick snapshot of the color’s composition. This simplification is particularly useful for memorizing brand colors or making rapid design decisions.
Translating Hex to Human Perception
The core of David’s method lies in converting RGB values into the HSL (Hue, Saturation, Lightness) model, which is more aligned with human perception. By analyzing the line graph of a hex code’s RGB values, developers can identify the hue (e.g., orange for high red, medium green, low blue), lightness (based on the average value of the channels), and saturation (determined by the range between the highest and lowest values). For instance, #D92
is described as a “middle washed orange,” a human-readable descriptor that bridges technical code and visual understanding.
David’s approach is not just practical but also philosophical, encouraging developers to think beyond tools and frameworks. By scrutinizing hex codes at a granular level, developers gain insights into color theory and workflow efficiency, ultimately enhancing their craft.

[DotCSS2018] DotCSS 2018: Florian Rivoal – Mastering Line Breaking in CSS
Florian Rivoal, a distinguished expert in web standards and co-editor of the CSS Text Module Level 3 specification, delivered an insightful presentation at DotCSS 2018 in Paris. His talk demystifies the intricate world of line breaking in CSS, shedding light on the white-space
property and related mechanisms that govern text layout. Florian’s expertise provides a clear lens through which developers can understand and manipulate text wrapping, ensuring both aesthetic and functional precision in web design. This post explores the key concepts Florian presented, offering practical insights for developers aiming to enhance their typographic control.
Understanding the White-Space Property
At the heart of Florian’s discussion lies the white-space
property, a cornerstone of text layout in CSS. This property dictates how sequences of spaces, tabs, and line feeds are handled within an element. Florian emphasized its versatility, noting that it applies not only to block elements like paragraphs but also to inline elements such as spans. This flexibility allows developers to fine-tune text behavior across diverse contexts.
For instance, with white-space: normal
, spaces around line feeds are collapsed, and line feeds themselves are converted to spaces, enabling natural wrapping. In contrast, white-space: nowrap
eliminates wrapping opportunities, keeping text on a single line. Florian also introduced white-space: pre-line
, which preserves line breaks as forced breaks while collapsing spaces, and white-space: pre
, which retains all whitespace characters, including tabs, without allowing wrapping unless explicitly permitted. The nuanced white-space: pre-wrap
and break-spaces
variants further refine this behavior, with the latter allowing breaks within sequences of preserved spaces.
These distinctions are critical for developers working on layouts where precise control over text flow is essential, such as in code snippets or poetic formats. By mastering these values, developers can ensure that text aligns with both design intent and user expectations.
Navigating Line Breaking and Overflow
Beyond the white-space
property, Florian explored additional tools for managing line breaks, particularly the overflow-wrap
property (formerly word-wrap
). This property becomes vital when text exceeds its container’s boundaries, provided wrapping is permitted by the white-space
setting. For example, overflow-wrap: anywhere
allows the browser to break text at any point to prevent overflow, a feature particularly useful in responsive designs.
Florian also delved into the hyphens
property, which introduces wrapping opportunities within words. By setting hyphens: auto
and specifying the lang
attribute, browsers can insert hyphens based on language-specific dictionaries, enhancing readability in languages like English or French. However, he cautioned that incomplete browser support, particularly in Chrome for certain platforms, can pose challenges. Similarly, the word-break
and line-break
properties offer advanced control, especially for languages like Japanese, where breaking rules differ due to the absence of spaces.
These tools empower developers to craft layouts that respect linguistic nuances while maintaining visual harmony. Florian’s examples, such as preventing unwanted breaks in Japanese text or ensuring poetic line breaks, underscored the practical applications of these properties in real-world scenarios.
