The new New Typography

Replacing the book production ecosystem with webpage production tools

In the 1920s and 1930s in Europe there was a movement known as the New Typography. It was a movement that rejected traditional type set in symmetrical columns and instead treated the printers block as a blank canvas to be explored in its entirety. The calling card of the movement was type arranged in harmonious and beautiful asymmetrical compositions. In the last 2 years there is another slow breaking wave of typographical exploration. The printers block is now HTML and CSS and Javascript are fast becoming the new tools of the typographer – not just for the web, for ebooks and for print, and not just for printed books, but for all printed material.

Browser as typesetting machine

The change of the books basic carrier medium from paper to HTML (the stuff webpages are made of) has meant many changes to what we might still call typesetting. Kindle and other e-ink devices actually move ink on a display to form words, sentences and paragraphs. The moveable type of Gutenberg’s time has become realtime, in a very real sense each book is typeset as we read it. Content is dynamically re-flowed for each device depending on display dimensions and individualised settings to aid readability. Moving type in ‘read time’ marks a significant paradigm shift from moveable type systems, including digital moveable type manipulated by Desktop Publishing software, to flowable typesetting. We are leaving behind moveable type for flowable type.

The engine for reflowing a page in realtime is something we have seen before. It is the job of the browser. And, since ebooks are webpages, browsers have come to play a central role in digital ereaders. In the case of the iPad the iBook reader is actually a fully featured browser engine; Webkit, the very same technology behind the Chrome and Safari browsers. Browsers are the typesetting machines for ebooks.

What is interesting here is that the browser can also reflow content into fixed page formats like PDF which means that the browser is becoming the typesetting engine for print. CSS and Javascript are the print design tools of our immediate future and the vast majority of innovations in this area are based on Open Source and Open Standards.

The power of CSS and Javascript

CSS is the set of rules used by the browser to know where to place type, images and other elements on a webpage and style those elements. Typical rules define where an image is placed in relationship to text, what fonts used, the font size, background color of the page, and the maximum width of an image, etc. While designed originally for the exclusive application to webpages the CSS Working Group, responsible for overseeing the development and direction of CSS, anticipated the intersection of the book and the web some time ago. In the latest drafts of the CSS standards new additions are almost entirely focused on typography and page control. As a consequence this area is starting to blossom. In particular, the CSS Generated Content for Paged Media Module specification is astonishing for its reframing of flowable text into a fixed page. Cross reference and footnote controls, not needed on the web, are among many book-like structure controls being addressed by CSS. Table of contents creation, figure annotations, page references, page numbers, margin controls, page size, and more are all included. The definition of these rules precede their adoption in browsers, however they are being included in browser engines, notably Webkit, at a very fast pace.

Coincidently there has recently been an explosion in interest in improving browser typography primarily for the better design of websites. Although these advances have not been made with book production in mind these advances can be inherited by the browser for typesetting both electronic and paper books. Of interest is the sharp rise in the websites offering tips on CSS typography an explosion of web fonts, and some very interesting Javascript libraries.

Javascript is the programming language of the web and it can be used to create dynamic content or manipulate objects on a webpage in ways CSS can not, or can not yet. Of particular interest is Kerningjs, inspired by the previously available letteringjs library. These code libraries allow you to change each letter individually in a paragraph or heading and control the spacing between letters (called ‘kerning’). Kerning is essential for printed books, and ebooks, but missing from browsers for a very long time. Colorfont is another Javascript library which enables dual toned glyphs, and the amazing TypeSet Javascript emulates the sophisticated TeX line spacing algorythims developed by Donald Knuth. Even the layout of musical notation (which was never effectively mechanised with Gutenberg’s moveable type and was hand written into books for many decades after the printing press came into the world) has come into focus with the VexFlow Javascripts. With libraries like this it is apparent that Javascript, the programming language of the browser, has a future with typography, and with that Javascript is fast becoming the lingua franca for all typesetting.

There is a lot of fuel in these developments and, interestingly, most of it is coming from outside the traditional print and publishing industry. It could be said that these industries, built upon the printing press, have lost sight of their very foundation. Instead the IT industry is taking hold on a very deep level. Apple and Google are behind the development of Webkit – the rendering engine behind iBooks, Safari and Chrome – which makes a lot of these typesetting innovations possible. Apple utilises these typographical features not just in its browser, but in the development of its iBook reader – the ebook reader on iPad which is itself based on Webkit. Google also fuels these innovations for many reasons other than the browser – better typography in Google Docs being one of them. We can expect the momentum to build and it is possible to say with some confidence that the browser, together with CSS and Javascript is to become the most important typesetting engine of our time as it is fast becoming the typesetting mechanism for digital and paper books and the web.

Ease and efficiencies

The implications for this are enormous and possibly not yet fully realised. At publishing industry conferences and other book-focused forums the attention has largely been on the ebooks effect on distribution, ereaders and the demise of the so-called brick-and-mortar book stores. The biggest effects however are elsewhere, ‘bubbling under’ in the recasting of the browser as a typesetting engine, and with it the slow realisation that the technical ecosystem surrounding book production can be replaced by tools for producing webpages. We are beginning to turn our attention to the tools for making webpages, to make books, and this, it turns out, is much easier than with Desktop Word Processing and Publishing software. Additionally due to recent developments, all of this, as it turns out, can also be used to design print (more on in-browser print production in a future post). Book production once again is becoming faster and cheaper and on its way to achieving another leap of magical efficency.

The future of book production right now is exploding all around us. These pieces of the puzzle are coming together and coming together fast. We can almost watch in real time the necessary mechanics get filled in by new release candidates of major browsers and searching online for ‘out of the blue’ small innovations such as Javascript typography controls. It is getting easier and easier to make books in the browser and consequently there has never been a time when it has been this easy to make books of all kinds. Ease of production is where it all started for Gutenberg and it is starting again for us. If you believe Gutenberg’s efficiencies changed society forever then what effect will the new new typesetting engines have? Its a giddy question. Making books in the browser will have an enormous impact on society as a whole, and just like the printing press, it will not revolutionise the old order, but create a new one.

Serializing CSS: The Definitive Guide

A new approach to publishing for a classic title.

By Eric Meyer, Author and Simon St.Laurent, Editor

O’Reilly is taking a new approach to publishing one of its classics, CSS: The Definitive Guide. The Fourth Edition will arrive in bookstores sometime soon, but long before then you’ll be able to buy sections of the book on more tightly-focused topics. The first three just came out:

We expect that this will work better for readers, the author, and the publisher, but the reasons are all different even though they interlock.

For readers

Some readers tell us (O’Reilly) that they want the latest and greatest and don’t worry as much about quality. Some readers tell us that they want every “i” dotted and every “t” crossed. Serialization lets us achieve both of those goals. The content comes out much faster, but it’s already been copyedited, reviewed, and illustrated. There may be updates to come if the content changes or errata (inevitably) turns up, but O’Reilly has polished each piece before its release. It may not yet be perfect, but it should be comparable to our usual finished books.

CSS: The Definitive Guide is large and getting larger as CSS grows. The writing process will take a long time, and in the traditional model content written at the beginning might wait a year or more to see customers. This new approach gets content out, and makes it much easier to fix things when content goes out of date.

With serialization, readers get much faster access to the most recent information, and customers who buy the ebooks will also get updates if the pieces they buy change. They can also buy the pieces secure in the knowledge that if they want to buy the whole thing later, O’Reilly will make sure they don’t lose their early investment: we’ll make sure that the price paid for the pieces becomes a discount on the larger work for readers who want the whole thing eventually.

You can also pick which pieces you want. Some people want huge definitive books. Others want just the pieces that fit their particular focus. If you only need three pieces of CSS: The Definitive Guide, you’l be able to buy just those three pieces. Read more…

Ask the Ebook Experts: Text alignment in Fixed-Layout EPUB for iBooks

How to mimic flowing text in a non-reflowable format

Q: In a traditional printed book, if a paragraph has not finished when the end of the page is reached, the entire paragraph will be justified. However the [CSS] command ‘text align last’ does not seem to be honoured in the last paragraph of the page in fixed layout for the iPad…What seems to happen is that in [InDesign CS6] it ‘looks’ justified but it doesn’t make it through to the epub version and there is a small gap at the end of the line. If you add text it goes on to a new line. I tried adding whitespace but that didn’t seem to be accepted…Is the problem with ibooks? Is there any workaround?

Andrew Rafferty

A: When you load a standard EPUB file into iBooks, the application automatically paginates the HTML content based on screen size and settings set by the user (font and font size). Content flows from page to page, and if a paragraph spans a page break, text alignment will be consistent on both pages.

Fixed-layout EPUBs differ from standard EPUBs in that it is the ebook designer who sets the pagination of the book, not the iBooks application. Each XHTML document in a fixed-layout EPUB file corresponds to a distinct page in the book, and no content is flowed from one page to the next.

If you want to mimic a text flow from page to page in a fixed-layout EPUB, you’ll need to split the text between two separate HTML documents. This poses a challenge if you want your text to be justified, because the text-align: justify CSS property does not stretch the final line of a paragraph to the full text-column width.

The good news is that CSS3 offers a solution to this very problem: the text-align-last property, which allows you to indicate how the final line of a text block is aligned. text-align-last: justify specifies that the final line should be fully justified, and span the full text column width.

The bad news about this good news is that text-align-last is not yet fully honored across all major Web browsers. It is supported in Mozilla-based browsers (Firefox), but is not supported in the Webkit engine, which powers Safari, Chrome, and—sadly—the iBooks ereader. Neither text-align-last nor the WebKit-specific -webkit-text-align-last, nor the EPUB3-specific -epub-text-align-last will produce the desired effect in the iBooks reader.

But some more good news for the intrepid and patient is there’s a hack-y HTML/CSS workaround that can achieve the effect of text-align-last: justify in iBooks (your mileage may vary on other ereader platforms).

Tweak word spacing using CSS

The old-school (dating all the way back to CSS1) word-spacing property allows you to designate a specific amount of space to place in between words. The following example uses word-spacing: 7px to specify that the last seven words on the page should have seven pixels of whitespace between them:

<p>Everywhere there are mysteries. And the most ancient man-made wonders
of all are the stone monuments erected by our Neolithic and Early 
bronze Age ancestors between 4000 and 1500BC - or, if it is less difficult 
to visualize in this way, between 140 and 240 generations ago. Little 
England (and smaller Scotland and Wales) are rich in these megalithic 
structures. Archaeologists tell us that more than a thousand chambered 
tombs and some 700 stone circles have resisted the 
smoothing iron of wind and rain, the teeth of the plough, the 
<span style="word-spacing: 7px">grasping hands of wave 
upon wave of</span></p>

And here’s a screenshot illustrating how this text renders in iBooks.

The main benefit of this approach is that it gives you fine-grained control over the whitespace in a paragraph. The downside is that it can require a fair amount of trial and error to determine the proper word-spacing values to achieve the desired justification effect. If you do decide to use this method, and have a paid iTunes Connect ebooks account, I highly recommend using Apple’s Book Proofer tool, as it eliminates much of the hassle involved in syncing EPUB files between your computer and your iPad/iPhone/iPod.

CSS in an XML Workflow

At the StartWithXML Forum in New York in January, Rebecca Goldthwaite of Cengage gave a great demonstration of how Cengage uses CSS in their XML workflow. Many publishers regard style sheets as an invitation to create cookie-cutter book production, with the fear that all their books will look the same. This is emphatically a myth. Have a look at her…
