[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: 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: 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.
