supporting certain platforms

SLIDE 33

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; ...}

slide-34
SLIDE 34

Adjusting for narrow screen

Don’t try to fit too much in a single paragraph—float on

  • ne side or other, but

not both! Don’t indent excessively

slide-35
SLIDE 35

Adjusting for narrow screen

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

slide-36

iBooks and fonts

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

slide-37
SLIDE 37

Cross platform dilemmas

slide-38
SLIDE 38

Discretional page breaks

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

slide-39
SLIDE 39

Discretional page breaks

Both NOOK and NOOK Color support all page-break properties

slide-40
SLIDE 40

Discretional page breaks

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

slide-41
SLIDE 41

Discretional page breaks

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

slide-42
SLIDE 42

Widows and orphans

.body { widows: 3;

  • rphans: 3;

}

slide-43
SLIDE 43

Widows and orphans

Neither iBooks nor Kindle Fire support widows or orphans

slide-44

Tables

slide-47

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>

Neither does NOOK

slide-52

Tables

Results are pretty awful on Kindle

slide-53
SLIDE 53

Audio and Video

iBookstore: yes, B&N + Amazon: no

slide-54
SLIDE 54

Fixed Layout

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

slide-55
SLIDE 55

Javascript

Works best in iBooks; allowed in iBookstore Sketchy support on

  • ther platforms
slide-56
SLIDE 56

Read Aloud

iBooks and Kobo Vox only; media

  • verlay on top of fixed layout; laborious
slide-57
SLIDE 57

Informed choices

  • How to create the best ebook that

works on the most platforms

  • Sometimes, you’ll decide to leave some

devices behind
