CSP: style-src-attr

The HTTP Content-Security-Policy (CSP) style-src-attr directive specifies valid sources for inline styles applied to individual DOM elements.

CSP version	3
Directive type	Fetch directive
`default-src` fallback	Yes. If this directive is absent, the user agent will look for the `style-src` directive, and if both of them are absent, fallback to `default-src` directive.

Syntax

One or more sources can be allowed for the style-src-attr policy:

Content-Security-Policy: style-src-attr <source>;
Content-Security-Policy: style-src-attr <source> <source>;

style-src-attr can be used in conjunction with style-src:

Content-Security-Policy: style-src <source>;
Content-Security-Policy: style-src-attr <source>;

<source> can be any one of the values listed in CSP Source Values.

Note that this same set of values can be used in all fetch directives (and a number of other directives).
