XHTML (Extensible HyperText Markup Language)
XHTML is a reformulated hybrid version of HTML with XML. One of its primary intensions was to help ensure uniform layout and page presentation across multiple platforms.
There are a couple versions of this standard:
- XHTML 1.0 Strict
This is the same as HTML 4.01 Strict, but fully enforces XML syntax rules.
- XHTML 1.0 Transitional
This supports everything found in XHTML 1.0 Strict, but also permits the legacy use of a number of elements and attributes that are now judged presentational and will eventually be deprecated. The purpose of XHTML 1.0 Transitional is simply to ease the transition from HTML to the new standards.
Some sites examples adhering to XHTML Standards:
- Stride-R-Web (Strict)
- New England Hosta Society (Transitional)
- J&L Orchids (Transitional)
