Does this directive do anything?

{: codeblock}

I used to use it at the end of a code block because the "copy to clipboard" function that I used required it. I believe the new Jekyll template no longer requires it. Is it being used downstream or for a purpose of which I am unaware?

[johnwalicki]

@joewxboy I don't know the providence of the {: codeblock} directive. I think Rene uses it downstream?

[johnwalicki]

@joewxboy - Yes, I confirmed. The downstream documentation requires the {: codeblock} directive to show the Copy to Clipboard icon. I found a downstream page where the directive is missing from a code block - and that section does not have a Copy to Clipboard icon.

Thanks. I'll add to Best Practices.
