Oliver Reichenstein,

Web fonts will bring a typographic revolution to

web design as great as desktop publishing was to

print design

M A K E A P R E D I C T I O N

“Optimizing typography is optimizing

readability, accessibility, usability,

overall graphic balance. Organizing

blocks of text, isn’t that what graphic

designers, usability specialists,

information architects do? So why is

it such a neglected topic?”

Oliver Reichenstein, 2006

W H Y H A S T Y P O G R A P H Y B E E N N E G L E C T E D ?

• The first argument against rich typography online used to be that there are only a few fonts available

• The second argument used to be that screen resolutions are too low, which makes it hard to read pixelated or anti-aliased fonts in the first place

• Browser support • Copyright issues • It’s easy to use defaults

Much of the web is about reading

“Designers will benefit from [approaching] their work now and again as being written rather than assembled.”

Dean Allen, A List Apart, 2001

Good typography enhances that experience

dizzying array of typographic terms

baseline, cap height, condensed, descender, drop cap, em, em space, em quad, hanging indent, kerning, discretionary ligature, swash, smallcaps, stylistic sets,

x-height, tracking, bowl, ascender, accents, alternates, counter, diacritics, hinting, leading, terminals, lining figures ...

• Text is too small • Lines are too long • Not enough whitespace • Poor layout consideration of titles and subtitles • Links are not clear (missing active and visited states

most of the time) • Text is not treated as part of the interface but in a

decorative fashion • Poor typeface choices

why OpenType?OpenType offers an accessible and advanced typographic toolset. !

It improves on PostScript and TrueType in a number of ways: One style in one file While Postscript is limited to 256 characters in a file, a single OpenType file can contain 65,535 characters or glyphs This allows for extensive language support as well as space for advanced typographic features

WOFF will winE M E R G I N G S TA N D A R D

WOFF uses a compressed version of the same table-based sfnt structure used by TrueType, OpenType, and Open Font Format, but adds metadata and private-use data structures, including predefined fields allowing foundries and vendors to provide license information if desired.

WOFF advantagesE M E R G I N G S TA N D A R D

Font data is compressed. Sites using WOFF will use less bandwidth and will load faster than if they used equivalent uncompressed TrueType or OpenType files.

Many font vendors that are unwilling to license their TrueType or OpenType format fonts for use on the web will license WOFF format fonts.

Both proprietary and free-software browser vendors support the WOFF format.

hello rich typography

O P E N T Y P E F E AT U R E S

Support widely expanded character sets and layout features which provide rich linguistic support and advanced typographic control

Using one font file only for its entire glyph, metric and bitmap data, OpenType fonts simplify font management

hello rich typography

Based on the Unicode Standard, a multi-byte character encoding that covers nearly all the world’s languages.

Includes non-standard glyphs, such as old-style figures, tabular figures, small capitals, fractions, swashes, superiors, inferiors, titling letters, contextual and stylistic alternates, a full range of ligatures, symbols and ornaments.

CSS fonts module level three

Working draft updated 3 October 2013

Introduces Font Feature Properties

Expands the font-variant property for CSS3

It now functions as a shorthand for a set of properties that provide control over stylistic font features

syntax (the real thing)

.i-have-a-class { font-family: 'myfont'; font-variant-ligatures: 'common-lig-values'; }

Values: normal, none, common-lig-values, discretionary-lig-values, historical-lig-values, contextual-alt-values

dizzying array of OpenType features

AALT, CALT, SALT, LIGA, DLIG, CLIG, HIST, HLIG, UNIC, SMCP, C2SC, PCAP, TITL, SWSH, SS01-20, FRAC, AFRC, ORD, NUMR, DNUM, SINF,

SUPS, SUBS, ONUM, PNUM, TNUM, ORNM ...

the whole listLanguage-specific display Kerning Ligatures Sub and superscript Capitalization Numerical formatting

Alternates and swashes Font specific values East Asian text rendering Overall shorthand for font rendering Low level settings control Font language override

awesome!

um ... no

let’s use them all now

browser support

well then ...

why are you wasting our time?

right now we have

support for low-level OpenType features via the font-feature-settings property

syntax (not the real thing)

.i-have-a-class { font-family: 'myfont'; font-feature-settings: 'smcp’, ‘swsh' 2; }

Values: the above syntax enables “Small Caps” and “Swashes”. The value is an integer. A value of zero would turn these features off.

“I can write the word 'dog' with any typeface and it doesn't have to look like a dog. But there are people that [think that] when they write 'dog' it should bark.” !

Massimo Vignelli

potential pitfalls

C AV E AT S

Just because we have lots of typefaces ... more fonts does not mean better typography !

Many current fonts are not optimised for the web !

Incomplete character sets, sub-optimal line heights, poor kerning !

Additional load time

C AV E AT S

Settle on a typeface as early as possible !

Get type in the browser as soon as possible !

Optimize loading on mobile !

Pay careful attention to line widths at breakpoints !

Use a baseline grid

C AV E AT S

Design for and use existing CSS properties that have widespread support !

Organise a design with regards to the message and with readability in mind !

Consider a hosted solution

Thanks for

listening !
