LightboxGallery und Pfeile und Esc
Hallo liebe Gemeinde,
auf meiner Homepage möchte ich eine photo-gallery mittels light Box einbinden.
Dazu habe ich folgendes JS - schnipsel gefunden:
Quelle: https://codepen.io/sidtheangel/pen/ONRKZa
Das hat so weit auch ganz gut funktioniert.
Weiters würde ich gerne noch 2 Funktionen hinzufügen.
1: der User soll sich mit dem Cursor - tasten (links & rechts) durch die Bilder „klicken“ können.
2: mit der ESC - tasten soll die light Box geschlossen werden. (so, als würde man auf das X klicken..)
da ich allerdings keine Ahnung von JS habe und mal schwer vermute, irgendetwas im *.js file dafür verändern/hinzufügen zu müssen, wollte ich mich an euch wenden.
danke schonmal für eure antworten!
liebste grütze & ein fröhliches neues jahr wünschend,
medhusa
