Chapter Two. Designing and Building with... > Transitional Forward Compatibility

Transitional Forward Compatibility

Ingredients

  • Valid XHTML for markup. (HTML 4.01 can also be used.)

  • Valid CSS for control of typography, color, margins, and so on.

  • Light use of XHTML tables for layouts, avoiding deep nesting by letting CSS do some of the work.

  • Optionally: Structural labels applied to significant table cells (facilitates CSS and scripting and helps with next year's transition to table-less CSS layout).

  • DOM-based JavaScript/ECMAScript, possibly with code forking to accommodate 4.0 versions of IE and Navigator.

  • Accessibility attributes and testing.
