Probleme und Herausforderungen beim Ausrichten von Bildern in Flexbox
Ich habe an einer Homepage gearbeitet, die ich kürzlich entwickelt habe, und habe einige Schwierigkeiten, meine Artikel in der Flexbox auszurichten. Die erste Flexbox sollte drei (3) Bilder enthalten und alle Bilder sollten in einer vertikalen Linie untereinander liegen.
通过此修订，一旦包装在 <main> 标记（或 <section>、<article>...）中，上述 HTML 可能会变成如下所示：
Unsere Immobilien
PlaceKitten image: 1
PlaceKitten image: 2
PlaceKitten image: 3
PlaceKitten image: 4
PlaceKitten image: 5
PlaceKitten image: 6
