Can I use V4 components in my V3 site?
Yes. Copy a V4 component in, then style it to match your site. You just need the atomic editor turned on in Elementor.
Custom CSS
The CSS to make the animation for this power up is included in the top level parent container Advanced > Custom CSS. No additional setup needed. Just copy the component and the styles come with it.
