Creare indicatori con HTML

Puoi utilizzare HTML e CSS personalizzati per creare indicatori di grande impatto visivo, che possono includere interattività e animazione. Tutte le istanze di Marker3DElement vengono aggiunte al DOM come elementi HTML, a cui puoi accedere utilizzando la proprietà Marker3DElement e manipolare allo stesso modo di qualsiasi altro elemento DOM.

Gli indicatori HTML personalizzati offrono prestazioni inferiori rispetto agli indicatori 3D standard. Per le applicazioni con set di dati di grandi dimensioni, indicatori standard sono vivamente consigliati per garantire prestazioni ottimali.

  0%   { transform: translateY(0); }

  55%  { transform: translateY(-5px); }
  75%  { transform: translateY(-10px); }
  100% { transform: translateY(-8px); }
