Using RapidWeaver 'Tipster' stack
Using Tipster
First you need to add a link to the object (image say) that is to have the hover box annotation:
Select the image
Click ‘Link” (bottom centre of the main RW pane)
Enter URL - #
Click on ‘+’ in the ‘Custom Attributes:’ and add an ‘id’ field and value (image_1 say)
Next, add a Tipster stack and include a text or markdown stack which will be the text in the pop-up annotation.
Use the ‘id’ value you created before as the Tipster ‘Target ID:’
Choose the format of the pop-up you want and anything else you fancy
