"description": "Vor Flexbox erforderten selbst einfache Layouts Floats, Positionierungs-Hacks oder tabellenbasierte Layouts. Flexbox (Flexible Box Layout) revolutionierte CSS, indem es ein eindimensionales Layout-System speziell für Platzverteilung und Inhaltsausrichtung bereitstellte.<br><br><strong>So funktioniert es:</strong> Wenn du <kbd>display: flex</kbd> auf ein Element setzt, wird es zum <em>Flex-Container</em>. Seine direkten Kinder werden automatisch zu <em>Flex-Items</em>, die entlang einer Hauptachse fließen (standardmäßig horizontal). Diese eine Eigenschaft verwandelt gestapelte Block-Elemente in eine horizontale Reihe.<br><br><strong>Die zwei Achsen:</strong><br>• <em>Hauptachse</em> – Die primäre Richtung, in der Items fließen (row = links→rechts)<br>• <em>Querachse</em> – Senkrecht zur Hauptachse (row = oben→unten)<br><br><pre>.nav {\n display: flex;\n}</pre>",
