Die W3C-Organisation gibt Stilvorschläge für die Erstellung von HTML4_HTML/Xhtml_Webseiten

Dies ist der HTML4-Stilvorschlag der W3C-Organisation. Leider haben Browser ihre eigenen privaten Attribute hinzugefügt, sodass der Standard im Dunkeln bleibt. Aber es ist für uns immer noch von großer Referenzbedeutung. Anhang D. Standard-Stylesheet für HTML 4Dieser Anhang ist informativ, nicht normativ.

Dieses Stylesheet beschreibt die typische Formatierung aller auf HTML 4 ([HTML4]) basierenden Elemente Umfangreiche Recherche zur aktuellen UA-Praxis wird empfohlen, es als Standard-Stylesheet in ihren Implementierungen zu verwenden.

Die vollständige Darstellung einiger HTML-Elemente kann in CSS 2.1 nicht ausgedrückt werden, einschließlich ersetzter Elemente („img“, „Objekt“), Skriptelemente („Skript“, „Applet“), Formularsteuerelemente und Rahmenelemente.

Für andere Elemente kann die Legacy-Präsentation in CSS beschrieben werden, aber die Lösung entfernt das Element. Beispielsweise kann das FONT-Element durch Anhängen von CSS-Deklarationen an andere Elemente (z. B. DIV) ersetzt werden. Ebenso kann die veraltete Darstellung von Präsentationsattributen (z. B. das „border“-Attribut in TABLE) in CSS beschrieben werden, das Markup jedoch in Das Quelldokument muss geändert werden
