trovare un comando in questo codice

[Threepwood]

salve a tutti!

questo codice in pratica gestisce delle transizioni a dissolvenza fra vari elementi.

Solo che mi sposta tutto a destra gli elementi. Vorrei capire dove è che va a spostare l'elemento da visualizzare (o magari cambia solo un absolute in relative)

Riuscite a capire quantomeno dove va ad agire sul posizionamento?

ore che lo cerco epoi è sotto gli occhi...
document.getElementById(divs[i]).style.position = "absolute";

invecchio....
