Chapter 2 Allowing Specic Protocols, CSS Styles, and HTML Tags and Attributes 33

For example, to allow the use of the font-size style attribute, create the following block:

<key>styles</key>

<array>

</array>

To allow the HTML “style” attribute, add the “style” attribute to the “_all_” tag, which is

described in the following section.

Allowing Specic HTML Tags and Attributes

YouTube, Flash, and other advanced web formats usually require HTML tags and

attributes that aren’t allowed by default. For example, YouTube requires the following

tags and attributes:

Tag Attributes

object width, height

param name, value

embed src, type, width, height

Because these HTML tags or attributes aren’t included in the built-in whitelist, you

must add them to the custom whitelist.

To allow specic HTML tags and attributes:

1 Create a tags key and follow it with a dict.

2 In the dict, create keys named after the HTML tags.

To allow a specic attribute for all HTML tags, create a key named “_all_”.

3 After each key, create string arrays listing allowed tag attributes.

For example, to support YouTube, create the following block:

<dict>

<key>object</key>

<array>

<string>width</string>

<string>height</string>

</array>

<key>param</key>

<array>

<string>value</string>

</array>

<key>embed</key>
