Set up initial directories for grade level pages
Top of grade components done. Initial markup for curriculum list. Set up new sass design file for curriculum list.
Create nested curriculum list. Style list. Add javascript for hiding/showing of components.
Add some new web font icons for hide and show curriculum components. Add those icons to the common elements page. Refine styles for curriculum list. Add new color variable so we can differentiate nested curriculum and make them stand out better. Add placeholder 1, 2, 3 icons for units.
Update unit header to use placeholder icon.
Adding horizontal padding on nested lessons so they don't bump up against the bg color.
