Strict HTML - using style sheets for presentation and doing away with <font> tags, align="" attributes and no <i> tags.
* XHTML Strict - Use this when you want really clean structural mark-up, free of any tags associated with layout. Use this together with W3C's Cascading Style Sheet language (CSS) to get the font, color, and layout effects you want.

The goal of Strict HTML is to separate content and structure from design.
