Hi All,
I haven't been able to find anyone else with a similar problem, but I have tested this on the Moodle Demo site and it appears to be the same. Forgive me if this has already been discussed.
Essentially, with Boost, HTML blocks do not appear to pull through custom CSS classes added in the block's setting page, despite the administration setting for allowing additional CSS classes being enabled.
I understand the move towards doing away with blocks, and this may be the reason, but it looks like the block.mustache template file has been set up to take over CSS class definitions, omitting the classes set by the block itself. In the case of the HTML block, this suggests that the additional classes are not included. Inspecting an element in-browser proves it.
I can include the classes again by adding them to the block's context In the core-renderer (boost/classes/output/). However, this includes all classes as defined by the block; block, block_html custom_css. This then duplicates the class definitions unless removed from the block.mustache file.
I suppose the question is whether this is by design, a fault or an oversight on my part?
