Note: The header of the card was updated to include an icon for the
module term and the footer was updated to include the percentage of
completion.

Description: Automatically dismiss the left or right sidebar when one of
them is selected on smaller screens. This solves the problem of
overlapping sidebars.

Note: This only applies to mobile devices (viewport width < 992 pixels)

Description: Hover transitions are much smoother now for buttons. Note that
this transition only applied to the background of the button.

Note: This is just an experimental commit to play around with this feature.
This may have to be adjusted in the case that cards contain other links in the
future.
