added nested table of contents
took out the old files from xml-xsl folder
trying to show each element in table of contents in the content wrapper, still on the way
for wider sidebar, changed width, margins etc to 400px (previously 250px)
maybe use these for slider, maybe not
mockup pics for testing
use variables instead of position() so that Lesson can display its intro if needed to. but pagination and collapse get messed up. maybe no need to use this.
trying slider instead of modal,still on the way to dynamically obtain slide content
reduced the amount of data for testing
change one column to two so that migmaq and english show side by side, not top-bottom
