Description
Is your feature request related to a problem? Please describe.
For long code-block
and code-cell
it would be nice to have a collapsed feature with a line specification. So for example it would load with only 20 lines showing and an ability to expand the block.

Describe the solution you'd like
Perhaps the tag could be collapse-n
where n is the number of lines? (i.e. collapse-20
would have a cell with 20 lines (or less if content is less) showing.
Describe alternatives you've considered
Not really any
Additional context
Would support displaying code cells like the one in this section:
