Custom container for block and inline

[chrisalley]

Thanks for sharing, @xoofx. Since we already numerous topics on custom containers/directives, I’m going to close this topic to prevent further duplication. For reference, here are some related topics where this extension can be discussed:

• Generic directives/plugins syntax discussion
• Spoiler tag syntax discussion
• Block directives discussion
• Content block discussion
• CSS classes on blocks discussion
• Alert/warning boxes discussion
