Heading

Headings strukturieren den Inhalt der Seite. Jede Heading hat dabei eine unterschiedliche Wichtigkeitsstufe.

Grundlagen

Headings strukturieren Inhalte sowohl visuell als auch inhaltlich. Sie helfen, sich auf einer Seite zu orientieren und die Relevanz einzelner Inhalte schnell zu erfassen. Jede Heading sollte klar und präzise den darunterliegenden Inhalt beschreiben. Headings werden häufig als erstes Element innerhalb von Sections verwendet. Die richtige Reihenfolge und Hierarchie der Überschriften ist entscheidend für eine verständliche und barrierefreie Struktur.

Best Practices

Achte bei der Verwendung von Headings darauf, dass ...

sie den Inhalt des folgenden Abschnitts eindeutig beschreibt.
sie kurz und sachlich formuliert ist.
die Hierarchie und Reihenfolge eine klare Seitenstruktur erkennen lässt (z. B. keine Sprünge von <h2> zu <h4>).
pro Seite nur eine <h1> verwendet wird.
sie häufig in Sections verwendet werden, um Inhalte zu strukturieren.

Verwendung

Verwende eine Heading, um ...

Seiteninhalte klar zu gliedern.
User durch den Content zu führen.
wichtige Abschnitte visuell hervorzuheben.
die semantische Struktur für Screenreader zu verbessern.

Playground

Verwende <Heading />, um eine Heading darzustellen.

Das ist eine Überschrift

import { Heading } from "@mittwald/flow-react-components";

<Heading>Das ist eine Überschrift</Heading>

Level

Über das Property level kann die Hierarchie der Heading angepasst werden. Standardmäßig wird eine Heading mit dem Level H2 erzeugt. Die Seite sollte eine sinnvolle Struktur mit verschiedenen Ebenen aufweisen.

Das ist eine Level 1 Überschrift

Das ist eine Level 2 Überschrift

Das ist eine Level 3 Überschrift

Das ist eine Level 4 Überschrift

Das ist eine Level 5 Überschrift

Size

Über das Property size kann in Ausnahmefällen die Schriftgröße einer Heading manuell angepasst werden. Die Headings sollten dabei eine visuelle Hierarchie beibehalten.

Das ist eine Überschrift für die eine benutzerdefinierte Größe gesetzt wurde

Color

Zusätzlich zu der Standard-Color, kann die Heading in Light und Dark dargestellt werden. Beide Colors eigenen sich, wenn die Standardfarbe auf farbigen oder dekorativen Hintergründen nicht gut funktioniert.

Das ist eine Überschrift

Light: Verwende die Light-Color bei dunklen Hintergründen mit einem HSL-Lightness-Wert unter 50.

Dark: Verwende die Dark-Color bei hellen, farbigen Hintergründen mit einem HSL-Lightness-Wert über 50.
