10 HTML 3.2 aims to capture recommended practice as of early '96
|
|
|
11 and as such to be used as a replacement for HTML 2.0 (RFC 1866).
|
|
|
12 Widely deployed rendering attributes are included where they
|
|
|
13 have been shown to be interoperable. SCRIPT and STYLE are
|
|
|
14 included to smooth the introduction of client-side scripts
|
|
|
15 and style sheets. Browsers must avoid showing the contents
|
|
|
16 of these element Otherwise support for them is not required.
|
|
|
17 ID, CLASS and STYLE attributes are not included in this version
|
|
|
18 of HTML.
