Hello,
How about moving the conditional to a helper in your first example? Just
curious to know if you would prefer that approach.
Thanks.

occurs from time to time is how to build HTML tags with different settings
depending on the some states. Here's an example of what I mean.

And I'm sure people here knows a few of them. However, none seem to really
make it easy to build them. So I decided to take a stab at it this weekend
and came up with this solution.

through a tag object that is available inside the block. Now, since this
might not be really easy to figure out how useful this could be, I created
a helper that overrides content_tag() and saved it as a gist for you to
test out locally. It's very possible that there's a few bugs as it's the
very first version.
