The new template (with public.css added): Type name: text Subtype name: css Required parameters: none Optional parameters: charset (but see below) Encoding considerations: For use with transports that are not 8-bit clean, quoted- printable encoding is recommended since the majority of characters will be CSS syntax and thus correspond to the US-ASCII-compatible subrange of UTF-8. Security considerations: CSS is a modular specification and thus, the individual Security Considerations section of each CSS module in use should be consulted. Interoperability considerations: CSS has proven to be widely interoperable across computer platforms, across Web browsers of different makes, and for import and export in multiple authoring tools. Published specification: https://www.w3.org/TR/css Applications that use this media type: CSS is device-, platform- and vendor-neutral and is supported by a wide range of Web user agents and authoring tools for formatting HTML documents. Fragment identifier considerations: N/A Additional information: Deprecated alias names for this type: N/A Magic number(s): N/A File extension(s): .css macOS Uniform Type Identifier(s): public.css Windows clipboard name(s): N/A Person & email address to contact for further information: The W3C CSS Working Group<[email protected]> Intended usage: COMMON Restrictions on usage: N/A Author: The W3C CSS Working Group Change controller: W3C Fallback encoding: For Web compatibility, to determine the character encoding, user agents follow the CSS Syntax Level 3 specification, "To determine the fallback encoding of a stylesheet" https://www.w3.org/TR/css-syntax-3/#determine-the-fallback-encoding Stylesheet authors should author their stylesheets in UTF-8, and ensure that either an HTTP header (or equivalent method) declares the encoding of the stylesheet to be UTF-8, or that the referring document declares its encoding to be UTF-8. -- Chris Lilley @[email protected] W3C Distinguished Expert, Color, Graphics & Fonts W3C Technical Programming Team, Core Web Design _______________________________________________ media-types mailing list -- [email protected] To unsubscribe send an email to [email protected]
