Oh, that's an interesting trick!

Can you please show a screenshot of how it looks on one of your page, with/without both and tags?

I'll try it myself, then merge your pull-request, and update the minified files.

I would also like to note that if HTML purists see your custom and tags, they won't be happy about them, but I don't care.

Thanks for taking a look!

Here's my page with <squirt> and <copyright>:

Here's my page without <squirt> and <copyright>:

I'm not sure, perhaps it would be better just to have one tag (<subtitle>, perhaps?) that allows complete customizability and covers the whole section, instead of being forced to used <squirt> and <copyright>.

I like your approach, as it allows to customize the location and content of the copyright notice.

I would also like to add an option, that works like the others currently supported by StrapDown.js :
see this page for more details : https://naereen.github.io/StrapDown.js/example5.html

I'll do it myself, probably adding nosquirt=y and nocopyright=y. Except if you have a better suggestion?
(I'll wait for a reply before merging this PR and adding my idea of these two tiny options)

That sounds like a good idea! It's certainly cleaner than only being able to have empty <squirt> and <copyright> tags, which is the only way to remove the squirt and copyright in the system I set up.
