I'm building an intro animation in Codepen and I wanted to tween the pseudo element `.marquee__tagline--logo::before`. I saw that this can be done using CSSRulePlugin, however it is just keeps throwing out errors.


The pseudo element is showing up in dev tools, and it clearly is rendering on the page, so I'm unsure of what I'm doing wrong here. Any help would be greatly appreciated!

Hah, well that's a bit embarrassing. That did indeed resolve my issue.


The Codepen is still very much a WIP so no worries about being unsure of what was going on. Thanks for the assist and for saving me from any more hours of trying to figure out where I was going wrong.
