![]() ![]() I know about the epubReadingSystem and its limitations. So I suppose it is possible only because I can see trough the inspector of ebook-viewer. That is why I tried to detect the viewport scale with this or this. I see that when 1:1 changes, it's some sort of scale in int numbers. In ebook-viewer (aka Calibre viewer) I can see in the inspector that every time I change the font size the console prints Viewport cfi: /2/4/2/2/1:1. A listener that measures the scale of the viewport.A timing event that measures the font size. ![]() I am trying to use or create and event listener when the user changes the font size of the EPUB in an ereader with Javascript but I haven't find the way. ![]()
