My answer to What is the difference between XHTML 1.0 strict and transitional? on Quora

Not a lot. XHTML transitional lets you use a few presentational attributes and elements that aren’t available in XHTML strict. Here’s a more detailed overview from back in 2005: http://24ways.org/2005/transitio...

These days you’re much better off using HTML5 and ignoring XHTML entirely.
