Rollover-Pictures in Rise360?

Frank, in Rise we use CSS, a hover effect with fading transition. This example is an overlay that includes labels to explain the graphic.

Hi Phil,

Thank you for your reply. Just to make sure I understand you correctly: This looks like I would have to edit the HTML-code generated by Rise after the course has been published, right?

I just don't know if I'm tech-savvy enough to try this - I'm afraid I would wreck the whole thing.
Is there a guide which tells me in detail how to "read" the code of a published rise-couse? -  i.e. a document that tells me "This folder contains all the CSS-information for your course" or "this style defines the font size of subheadings" etc.?
Kind Regards and thanks again - and sorry for my delayed response,
Frank

Frank, indeed this is a customization and does require knowledge of CSS. My recommended method is to leave all the existing css in the course alone, and add your own css file. This keeps your code separate makes it easier to duplicate to other courses.
