Publishing on Kindle: Guidelines for Publishers
Styling Guidelines 3.9
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}
div.subchapter { margin-left: 2em}
</style>
<div>Section 1</div>
<div class="chapter">Chapter 1</div>
<div class="chapter">Chapter 2</div>
<div class="chapter">Chapter 3</div>
<div class="subchapter">Subchapter 1</div>
<div class="subchapter">Subchapter 2</div>
<div class="chapter">Chapter 4</div>
<div class="subchapter">Subchapter 1</div>
<div>Section 2</div>
3.9.2 Styling Guideline #2: Format Sidebars Correctly
When inserting sidebar content into the main flow of a book formatted for Kindle Format 8, use float via
CSS. However, if the book is formatted for Mobi 7, use the <hr/> HTML tags before and after the sidebar
to differentiate it from the main body of text. Avoid using negative em values when specifying dimensions
for a float element.
HTML Guidelines 3.10
3.10.1 HTML Guideline #1: Constructing Well-Formed HTML Documents (XHTML)

constructing well-formed HTML documents:
