XHTML Strict - Is this right?

Bobby Edward · Oct 4, 2008

To use XHTML Strict all I have to do is...

1. Add this to the top of my master page/ASPX page(s)
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
2. Add this to my web.config "<system.web>" section
<xhtmlConformance mode="Strict" />

Correct????

Thanks. Do you know if this web.config setting takes precendence over the
DocType definition?

no, all the html and css you enter must follow the xhtml standard. you
should run your pages thru a xhtml compliance tool (visual studio has a
simple one, but it only checks the aspx source, not the rendered html).
also 3rd party controls may not generate compliant html.

There's a difference between HTML and XHTML.
For one, XHTML is a type of XML document and has a DTD, but it is based on
HTML 4.0
Check with the W3C http://www.w3.org/MarkUp/#recommendations
and here's a decent set of tutorials on both

Not correct.

That doctype tag is not an XHTML doctype, it's an HTML doctype. For an
XHTML page you need an XHTML doctype.
