3.7.5 Table Guideline #5: Optimize for Maximum Table Size

Optimize tables to be no larger than 10 Kindle screens. A Kindle screen is approximately 24 rows of 60 characters, although the Kindle DX shows more characters. The character limit is the maximum number of characters in any one row. There are a limited number of combinations for a table that looks like this

(see below). If a table has more characters than the maximum number specified below (given the number

of rows), split the table into smaller tables or images, as described in section 3.7.4, Table Guideline #4:

Split Tables as Needed. In this case, characters are non-formatting characters (the actual text that a user

sees when looking at the contents of a table).

Number of Rows Maximum

(Per Row)

1 - 24 600

25 - 48

49 – 72

72 – 120

121 – 240

3.8 Adobe Digital Editions Compatibility Guidelines

3.8.1 Adobe Digital Editions Compatibility Guideline #1: Use Unique Item IDs

When using Adobe Digital Editions, make sure that the item IDs in the manifest are unique. Adobe Digital

Editions does not enforce uniqueness of IDs, which is incorrect according to the IDPF standard.

<manifest>

<item id="css1" href="core.css" media-type="text/css"/>

<item id="css2" href="template.css" media-type="text/css"/>

...

</manifest>

3.9 Styling Guidelines

3.9.1 Styling Guideline #1: Use a Nested HTML TOC

To create useful, navigable, deep TOC entries, Amazon recommends using the following syntax in the

HTML TOC. The examples below show two ways of writing the same sample code: style attributes and

CSS classes.

Using style attributes:

<div>Section 1</div>

<div style="margin-left:1em;">Chapter 1</div>

<div style="margin-left:1em;">Chapter 2</div>

<div style="margin-left:1em;">Chapter 3</div>

<div style="margin-left:2em;">Subchapter 1</div>

<div style="margin-left:2em;">Subchapter 2</div>

<div style="margin-left:1em;">Chapter 4</div>

<div style="margin-left:2em;">Subchapter 1</div>

<div>Section 2</div>

Using CSS classes:

<style> div.chapter { margin-left: 1em}
