How these pages were coded

All pages of this site were hand coded using the plain text editor of HTML-Kit 292 (free). The application HTML Tidy (free) was used to "pretty print" the code.

About this page

Table free icon This page was hand coded using XHTML 1.0 (strict) Markup. It is served, using Content Negotiation (via PHP on the Server side), as Media type application/xhtml+xml to XML compliant Browsers and as Media type text/html to MSIE Browsers. The character set is utf-8 (Unicode). The Markup is styled using CSS level 3. It also features RDF/XML for Dublin Core Metadata and RSS Feed generation. This is an XHTML 1.0 (strict) demonstration page. I personally write my regular web pages using HTML 4.01 (strict) Markup and serve them as content type text/html.

HTML5 Polyglot Example page

The page validates as an HTML5 document served as content (MIME) type html/text. The character set is utf-8 (Unicode). The Markup is styled using CSS level 3. It also features RDF/XML for RSS Feed generation. Go to the HTML5 Polyglot Example page.
