Speciﬁcations

Manufacturer Guidelines

Objective:One ﬁle to rule them all

3 problems 1. They can’t do it.2. They want to do it their own way. 3. They won’t let you do it.

Three strategies• Create cross platform code• Use media queries when cross platform code isn’t possible• Make informed decisions about not supporting certain platforms

Everybody supports bold and italic font-size text-indent top and bottom margins images

Original iBooks on iPad iBooks/iPhone Adobe Digital Editions ->

Kindle Fire Kindle

NOOK NOOK Color

Many support font family small caps leading left and right margins ﬂoat and widthtext wrap (around images, sidebars, and drop caps) borders, backgrounds color

NOOK Color with Publishers Defaults OFF

Media Query example @media amzn-mobi {span.dropcap { span.dropcap { font-size : 5em; font-size : 3em; ﬂoat : left; ﬂoat: none; line-height : 1.5; line-height : 1; margin-right : 0.1em; margin-top : auto; margin-bottom: -.3em; margin-right : auto; font-family : margin-bottom: auto;DavysArtNouveauInitials, font-family : sans-serif;sans-serif; color : #512a37; color : #512a37; }} }

Kindle

Watch out for...

Aligning drop cap span.dropcap { ... line-height : 1; margin-top : .2em; margin-right : 0.1em; margin-bottom: 0em; ... } span.dropcap { ... line-height : 1.5; margin-right : 0.1em; margin-bottom: -.3em; ...}

Adjusting for narrow screen Don’t try to ﬁt too much in a single paragraph—ﬂoat on one side or other, but not both! Don’t indent excessively

Adjusting for narrow screen p.Poem-line { font-size: .8em; text-indent : -20px; margin : 0 0 0 20px ; padding: 0px 28px; }

iBooks and fonts Don’t forget the .com ﬁle or else iBooks won’t display embed fonts

Cross platform dilemmas

Discretional page breaks page-break-after: avoid Kindle, iBooks don’t support.

Discretional page breaks Both NOOK and NOOK Color support all page-break properties

Discretional page breaks But Kindle Fire and iBooks do support page- break-inside: avoid Create a div with header and ﬁrst paragraph.

Discretional page breaks iBooks supports page- break-inside: avoid (but no other “avoids”)

Widows and orphans .body { widows: 3; orphans: 3; }

Widows and orphansNeither iBooks nor Kindle Fire support widows or orphans

Widows and orphans Again, NOOK comes through

TablesVery problematic in narrow pages

Tables

Tables<manifest>...<item id="table1" href="table1.html" media-type="application/xhtml+xml" /><item id="table2" href="table2.html" media-type="application/xhtml+xml" />...</manifest><spine toc="ncx"><itemref idref="maintext" /><itemref idref="table1"/><itemref idref="table2" linear="no" /></spine>

Tables

TablesKindle Fire does not support non-linear tables

Tables Neither does NOOK

TablesResults are pretty awful on Kindle

Audio and VideoiBookstore: yes, B&N + Amazon: no

Fixed LayoutiBooks and Kobo Vox use very similar systems; NOOK has closed system, Amazon new system

Javascript Works best in iBooks; allowed in iBookstoreSketchy support on other platforms

Read Aloud iBooks and Kobo Vox only; mediaoverlay on top of ﬁxed layout; laborious

Informed choices• How to create the best ebook that works on the most platforms• Sometimes, you’ll decide to leave some devices behind
