Basic Tags
The following basic tags are supported:
•
—Defines the document type
•
—Defines a comment
<!DOCTYPE>
The <!DOCTYPE> declaration is the very first thing in your document, before
the <html> tag. This tag tells the browser which XHTML specification the
document uses. XHTML 1.0 specifies three XML document types: Strict,
Transitional, and Frameset.
• XHTML Strict
— Use this DTD when you want clean markup, free of presentational
clutter. Use this together with Cascading Style Sheets (CSS).
For example,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
• XHTML Transitional
— Use this DTD when you need to use XHTML's presentational features
because your readers don't have browsers that support Cascading
Style Sheets (CSS).
For example,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
• XHTML Frameset
— Use this DTD when you want to use frames.
For example,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
Frameset//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
This tag does not have any attributes.
