[NDCOslo2024] Accessibility by Everyone (and for Everyone) – Amy Kapernick
In an epoch where digital dominion dictates daily discourse, Amy Kapernick, a foremost accessibility advocate and consultant, issues an imperative: inclusivity as imperative, not afterthought. With a crusade rooted in user experience and universal design, Amy exposes the exclusions etched into everyday interfaces, advocating for architectures that accommodate all, from the able-bodied to the impaired. Her discourse, dynamic with demonstrations and data, democratizes accessibility, declaring it a collective charge that enriches existence universally.
Amy acknowledges her last-minute logistics—audio absent, yet ardor undimmed—yet plunges into profundity: technology’s ubiquity underscores urgency, as 1.2 billion with disabilities confront barriers baked into bytes. She shatters stereotypes: accessibility aids all—temporary tribulations like fractured limbs or fractured focus benefit from barrier-free builds.
Universal Usability: Beyond Barriers to Broader Benefits
Accessibility, Amy avows, amplifies agency: screen readers summon sightless surfers to seas of content, captions convey clarity amid clamor, alt text unveils visuals to the visionless. Her hierarchy of harmony: POUR principles—Perceivable, Operable, Understandable, Robust—guide guardians toward grandeur.
Amy animates with audits: color contrasts calibrated for chromatic challenges, keyboard cascades for motor maladies, semantic structures for scanner scrutiny. Overlays, she ostracizes: ostensible panaceas that exacerbate, overriding user overrides and inviting incursions.
Collective Custodianship: Crafting Change Collaboratively
Everyone, Amy emphasizes, owns obligation: developers discern deficits, designers dream diversely, managers mandate metrics. Her mosaic: small strides—semantic tags, focus indicators—sum to seismic shifts, serving seniors, multitaskers, multilinguals.
Resources ripple: her repository at capesa11y.com, a cornucopia of checklists and courses, catalyzes competence. Amy’s axiom: inaccessibility isolates, accessibility integrates—elevating equity in an equitable ether.

[PHPForumParis2021] Front-End Quality: Why It’s Also the Backend Developer’s Job – Martin Supiot & Élie Sloïm
Martin Supiot and Élie Sloïm, experts in web quality, delivered a compelling joint presentation at Forum PHP 2021, arguing that backend developers play a critical role in ensuring front-end quality. Representing Opquast, Élie, a pioneer in web quality standards, and Martin, a former AFUP treasurer, emphasized the interconnectedness of front-end and backend development. Their talk provided practical strategies for improving user experience through collaboration. This post explores four themes: shared responsibility, enhancing user empathy, optimizing error handling, and avoiding third-party dependencies.
Shared Responsibility
Martin Supiot and Élie Sloïm opened by challenging the siloed mindset of front-end versus backend development. They argued that backend developers, through their work on APIs and data processing, directly impact front-end performance and accessibility. Drawing on Opquast’s quality checklist, Élie and Martin highlighted how backend choices, like efficient API responses, influence user experience. Their collaborative approach at Opquast underscores the need for cross-functional teamwork to deliver high-quality web applications.
Enhancing User Empathy
A central theme was fostering empathy for users, particularly those with limited technical capabilities. Martin and Élie stressed that backend developers must consider how their code affects user interactions, such as ensuring clear error messages or accessible data formats. By prioritizing user needs, developers can create inclusive applications. Élie’s work with Opquast’s guidelines provides a framework for backend developers to align their work with user-centric front-end outcomes, enhancing overall usability.
Optimizing Error Handling
The duo emphasized the importance of thoughtful error handling, such as personalized 404 and 403 pages, to guide users effectively. Martin explained that a generic error page might lead users to blame their connection, whereas a well-crafted response provides clarity. While 500 errors are harder to test, Élie and Martin advocated for backend systems that deliver meaningful feedback, ensuring users remain engaged rather than frustrated, a principle rooted in Opquast’s focus on quality assurance.
Avoiding Third-Party Dependencies
Concluding their talk, Martin and Élie cautioned against relying solely on third-party authentication systems like Google or Facebook. They noted that such dependencies can exclude users without accounts, potentially losing 30% of a site’s audience. By designing backend systems that support independent authentication, developers can enhance accessibility and inclusivity. This approach, informed by Opquast’s best practices, ensures that backend decisions prioritize user access and engagement.

[DotCSS2018] DotCSS 2018: Mandy Michael – Variable Fonts Ushering in Typographic Horizons
Mandy Michael, an innovative front-end developer renowned for her CSS artistry, illuminated the transformative promise of variable fonts at DotCSS 2018. As a self-proclaimed tinkerer rather than a traditional designer, she demonstrates how these fonts transcend mere efficiency, unlocking realms of adaptive, interactive typography that harmonizes with the web’s fluidity. Michael’s discourse blends practical gains with visionary applications, positioning variable fonts as harbingers of a more nuanced digital vernacular.
Streamlining Performance While Amplifying Flexibility
Michael demystifies variable fonts as singular files encapsulating myriad styles, where traditional suites demand separate downloads for each weight or variant. Forged by designers via interpolable axes—spanning weight, width, or slant—these fonts grant granular access to intermediary values, from 100 to 900 in 1-unit increments. This continuum facilitates seamless animations, unmarred by the jarring leaps of static counterparts.
Browser compatibility, she assures, is robust across majors, with macOS High Sierra as the sole caveat for Firefox users. Performance perks shine in comparisons: Adobe’s Source Sans variable edition clocks in at 394 KB for exhaustive coverage, dwarfing the 924 KB aggregate of its static kin—even pruned selections. A lone network call supplants cascades of requests, synergizing with HTTP/2 for swifter loads. Yet, beyond bandwidth thrift, variable fonts liberate creativity; their slimmer profiles embolden bolder experimentation without fiscal remorse.
Michael illustrates with bespoke text effects—slimy oozes via Chi by Fontself or vanishing shadows in Dec—where axes morph glyphs in real-time, rendering editable, screen-reader-friendly prose that supplants cumbersome images or canvases.
Adaptive Typography for Inclusive, Dynamic Experiences
The true alchemy of variable fonts, per Michael, resides in environmental responsiveness. Axes like optical size or grade adjust legibility across devices—from wristworn smartwatches to expansive projectors—ensuring hierarchy endures. Scroll-triggered swells in Chi or proximity-based sizing via Sensor API exemplify this; fonts now converse with context, elevating readability in dim alcoves or glaring outdoors.
Emerging CSS media queries, such as prefers-color-scheme: dark, further this dialogue. Michael’s demo toggles oozing text in shadowed modes, blending transitions for intuitive shifts. Audio-responsive variants, attuned to vocal inflections, hint at conversational interfaces for voice assistants, visually encoding tone sans verbosity.
Accessibility amplifies: interpolated contrasts mitigate low-vision strains, while dynamic weights enhance scannability. Michael envisions fonts as APIs, manipulable by JavaScript for user-centric tweaks—be it luminance detection or gestural inputs. Though nascent, these facets dissolve erstwhile constraints, where performance once curbed flair. Now, content’s essence—its rhythm, intent—guides form, fusing print’s poise with web’s interactivity. As Michael avows, this epoch invites developers to sculpt purposeful, performant narratives, unhindered by yesteryear’s shackles.

[DotCSS2018] DotCSS 2018: Fabien Zibi – Prioritizing Semantic Order in Markup
Fabien Zibi, an accessibility champion with a keen eye for structural integrity, presented a cautionary tale at DotCSS 2018 on the perils of CSS-orchestrated reordering. Analogizing to George Lucas’s nonlinear Star Wars saga, he warns against scripting HTML in defiance of perceptual flow, advocating for markup that stands resilient, styled or stripped. Zibi’s concise admonition bridges styling prowess with equitable reading paths, ensuring assistive technologies mirror visual intent.
The Trap of Layout-Driven Markup
Zibi spotlights CSS Grid’s grid-area as a seductive snare, where named slots tempt authors to scatter content chronologically—say, Star Wars episodes in production sequence—only to reshuffle via styles for release chronology. This sleight, while visually adroit, fractures linear traversal: tabbing or screen reader sweeps adhere to source order, stranding users in narrative disarray.
His exemplar unfolds a gallery of film posters: initial HTML aligns with timeline genesis (Episodes IV-VI preceding prequels), mapped to grid slots via grid-area: movie-one. A stylistic pivot—reassigning areas to broadcast precedence—inverts display sans amending markup, yielding a facade of coherence atop navigational chaos. Keyboard focus leaps erratically, and vocal synthesizers recite anachronisms, eroding trust and efficiency.
Zibi stresses that CSS’s layout lexicon, potent as it is, must defer to HTML’s declarative primacy. Robust documents, he contends, derive meaning intrinsically, unyielding to visual whims— a principle fortifying not just accessibility but future-proof adaptability across devices and parsers.
Forging Resilient, Intent-Aligned Structures
To circumvent such pitfalls, Zibi implores authoring in the precise sequence of consumption: chronological for timelines, hierarchical for documents. This semantic fidelity ensures assistive flows—be they auditory or sequential—echo cognitive journeys, irrespective of stylistic interventions.
Even as Grid and Flexbox liberate from float follies, vigilance persists; properties like order in flex contexts pose analogous risks, demanding source-order primacy. Zibi’s ethos resonates universally: CSS embellishes, but HTML narrates. By embedding intent in markup’s marrow, creators safeguard inclusivity, transforming potential fractures into seamless continuums.
