Cascading Style Sheets (CSS) is a style sheet language for the World Wide Web. CSS style sheets have been in use since October 1995 using the Media Type text/css without registration; this memo seeks to regularize that position.

The World Wide Web Consortium has issued a Recommendation [1], which defines Cascading Style Sheets, level 1. This memo provides information about the text/css Media Type.

Cascading Style Sheets (CSS) is a style sheet language for the World Wide Web. It describes the presentation (e.g. fonts, colors and spacing) of structured documents. CSS is human readable and writable, and expresses style in common desktop publishing terminology.
CSS style sheets have been in use since October 1995 using the Media Type text/css without registration; this memo seeks to regularize that position.

このメモはその立場を正当化しようとするものです。
A CSS style sheet can be either:
CSS
(1) external - the style sheet is linked to a document through a URI and exists as a separate object on the Web. The media type text/css is used when fetching the object, for example in the Content-Type and Accept header fields of HTTP [2].
一、外部: text/css はContent-Type・Accept
両
(2) internal - the style sheet is contained within the document. A typical scenario is an HTML [3] document that contains a style sheet within the STYLE element. Due to this close relationship, HTML and CSS share the same top-level name ("text").
二、内部: 訳注: ほんとかよ?STYLE
"text")

Subject: Registration of MIME media type text/cssMIME media type name: text
MIME subtype name: css
Required parameters: none
Optional parameters: charset
The syntax of CSS is expressed in US-ASCII, but a CSS file can
contain strings which may use any Unicode character. Any charset
that is a superset of US-ASCII may be used; US-ASCII, iso-8859-X
and utf-8 are recommended.CSS の構文は US-ASCII で表現しますが、
CSS US-ASCII の上位集合であるどんな charset
でも使って構いません。 US-ASCII,
iso-8859-X, utf-8
を推奨します。
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 US-ASCIIでない転送路で使う時には、文字の大部分は CSS
構文であることから US-ASCII なので、
quoted-printable 符号化を推奨します。
Security considerations:
Applying a style sheet to a document may hide information
otherwise visible. For example, a very small font size may be
specified, or the display of certain document elements may be
turned off.文書に
CSS style sheets consist of declarative property/value pairs
assigned to element selectors. They contain no executable code.CSS
As with HTML documents, CSS style sheets may contain links to
other media (images, sounds, fonts, other style sheets) and those
links are typically followed automatically by software, resulting
in the transfer of files without the explicit request of the user
for each one. The security considerations of each linked file are
those of the individual registered types.HTML 文書と併用することで、 CSS
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.CSS は計算機

formatting HTML and XML documents.CSS は機器・
