CSS dashed border animation

I'm trying to do a dashed border animation similar to this,


Does anyone have something that they would be willing to share?

Googling 'CSS marching ants animation' has (a lot of) different approaches. If you stick to ones that are "pure" CSS, they should be relatively easy to adapt to Ignition, especially with the new advanced stylesheet feature.

I did that very thing, unfortunately I wasn't able to get anything to work (the ants were very lazy). I'll keep trying, thanks.
