Margin

The "Margin" setting controls the left and right margin you want to see when reading eBooks. The default options provided are

• Small: use small margins (maps to value "0")
• Medium: use medium margins (maps to value "0.5em")
• Large: use large margins (maps to value "1.0em")

The default margin is "Medium". If you are familiar with HTML and CSS, then you should know that any valid "margin-left" or "margin-right" value can be used here.

Note: This setting is applied at the top level eBook element and acts as a default setting. If lower level elements define margin options, then those will take precedence over this setting.
