Cet appendice est informatif, et non normatif.
Cette feuille de style décrit la mise en forme typique de tous les éléments HTML 4.0 ([HTML40]) à partir d'un examen approfondi des pratiques des agents utilisateurs actuels. On encourage les développeurs à l'utiliser comme feuille de style par défaut pour leurs implémentations.
La présentation complète de certains éléments HTML n'est pas exprimable en CSS2, ainsi les éléments remplacés (IMG, OBJECT), des scripts (SCRIPT, APPLET), des contrôles des formulaires et des cadres.
