| THE WEB STANDARDS GROUP RECOMMENDS a doctype of XHTML 1.0 Transitional in all Web pages AND validation to that standard. |
| The doctype tells a validator which version of HTML to use in checking the document's syntax. Here's how the Web Design Group describes XHTML 1.0 Transitional: |
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">
This declares the document to be XHTML 1.0 Transitional. XHTML 1.0 Transitional is an XML version of HTML 4 Transitional... HTML 4 Transitional includes all elements and attributes of HTML 4 Strict but adds presentational attributes, deprecated elements, and link targets. HTML 4 Transitional recognizes the relatively poor browser support for style sheets, allowing many HTML presentation features to be used as a transition towards HTML 4 Strict. - from Web Design Group |
| To name the doctype, the first line of the document looks like this: |
<!DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">
|
| WSG recommends validation to XHTML 1.0 Transitional and CSS 2.1. W3C provides free validators that check HTML and XHTML documents: |
