この仕様書は以下の項に分けられます
This specification is divided into the following sections:
SGML の簡潔な手引では、読者が SGML と HTML との関係について多少なりとも理解できるようにし、 HTML Document Type Definition （ DTD ）の読み方を要約して伝えます。
The brief SGML tutorial gives readers some understanding of
HTML's relationship to SGML and gives summary information on how to
read the HTML Document Type Definition (DTD).
この文書は、 HTML の文法よりは話題によってまとめられています。
話題としては、構造と提示と相互通信の３つのカテゴリーにまとめられます。
HTML 構造物をこの３つのカテゴリーに完全に分けてしまうことは容易ではありませんが、 模型には 、より効果的で管理しやすい文書の提示方法から文書の構造を区別する、HTML Working Group の実験結果が反映されます。
This document has been organized by topic rather than by the
grammar of HTML. Topics are grouped into three categories: structure,
presentation, and interactivity. Although it is not easy to divide
HTML constructs perfectly into these three categories, the model
reflects the HTML Working Group's experience that separating a
document's structure from its presentation produces more effective and
maintainable documents.
言語参照は、次の情報から構成されます：
The language reference consists of the following information:
HTML 文書に現れる字の種類。
What characters may
appear in an HTML document.
HTML 文書の基本的なデータ種別。
Basic data types of an HTML document.
文章・一覧・表組・連鎖、そして埋込みオブジェクト・映像・アプレットなど、HTML 文書の構造を決定する要素。
Elements that govern the structure of an HTML
document, including text, lists,
tables,
links, and
included objects, images, and applets.
スタイルシート・使用活字・色・線、その他の視覚的な提示、 複数の窓を提示するためのフレームなど、HTML 文書の提示を決定する要素。
Elements that govern the presentation of an HTML document,
including style sheets, fonts, colors, rules, and other visual
presentation, and frames for
multi-windowed presentations.
利用者書き込みのための書式や使用中の文書のスクリプトなど、 HTML 文書の相互通信を決定する要素。
Elements that govern interactivity with an HTML document,
including forms for user input and
scripts for active documents.
HTML の SGML 形式的な定義
The SGML formal definition of HTML:
この文書は、物書きとベンダ各社という2通りの読者を想定して書かれています。
仕様書が物書きたちにとって、 HTML の実装詳細に煩わされることなく、効果的で魅力的な、そして近付きやすい文書を書く道具となることを願っています。
しかしながらベンダ各社は、準拠するユーザエージェントを作り上げるために必要な全てを、自分たちの手で見つけるべきです。
This document has been written with two types of readers in mind:
authors and implementors. We hope the specification will
provide authors with the tools they need to write efficient,
attractive, and accessible documents, without over-exposing them to
HTML's implementation details. Implementors, however, should find all
they need to build conforming user agents.
仕様書にはさまざまなアプローチが可能です。
The specification may be approached in several ways:
始めから終わりまで読む。
Read from beginning to end.
仕様書は一般的な HTML の提示から始まり、終わりへ近づくにつれて次第に技巧的に、具体的になってゆきます。
The specification
begins with a general presentation of HTML and becomes more and more
technical and specific towards the end.
言語参照マニュアルの３つの項目の第一面では、初めの目次を各々の項目についてより精細に分けてある。
The front pages of the three sections of the language reference
manual extend the initial table of contents with more
detail about each section.
要素名は（BODYなど）大文字で書いてあります。属性名は（lang,onsubmitなど）小文字で書いてあります。
HTMLとしては、要素名も属性名も、大文字・小文字を区別しません。この書き分けは、単に読みやすさを求めてのことです。
Element names are written in upper case letters (e.g.,
BODY). Attribute names are written in lower case letters (e.g., lang,
onsubmit). Recall that in HTML, element and attribute names are
case-insensitive; the convention is meant to encourage readability.
この文書にある要素名と属性名による表記を特別に表現するユーザエージェントがあるかも知れません Element and attribute names in this document have been marked up and may be rendered specially by some user agents.
それぞれの属性の定義は、その値の種類を指定します。 Each attribute definition specifies the type of its value. If the type allows a small set of possible values, the definition lists the set of values, separated by a bar (|).
After the type information, each attribute definition indicates the case-sensitivity of its values, between square brackets ("[]"). See the section on case information for details.
Informative notes are emphasized to stand out from surrounding text and may be rendered specially by some user agents.
All examples illustrating deprecated usage are marked as "DEPRECATED EXAMPLE". Deprecated examples also include recommended alternate solutions. All examples that illustrates illegal usage are clearly marked "ILLEGAL EXAMPLE".
Examples and notes have been marked up and may be rendered specially by some user agents.
Thanks to everyone who has helped to author the working drafts that went into the HTML 4.0 specification, and to all those who have sent suggestions and corrections.
Many thanks to the Web Accessibility Initiative task force (WAI HC group) for their work on improving the accessibility of HTML and to T.V. Raman (Adobe) for his early work on developing accessible forms.
