A validator based on the pegboard::Lesson class cached with this_lesson()
that will provide line reports for fenced divs, links, images, and heading
structure. For details on the type of validators avaliable, see the
{pegboard}
article Validation of Lesson Elements
Value
a list with the results for each test as described in pegboard::Lesson
Details
Headings
We expect the headings to be semantic and informative. Details of the tests
for headings can be found at pegboard::validate_headings()
Internal Links and Images
Internal links and images should exist and images should have alt text.
Details for these tests can be found at pegboard::validate_links()
Fenced Divs (callout blocks)
Callout Blocks should be one of the expected types. Details for this test
can be found at pegboard::validate_divs()
