OT: Swift Theme: Adding animation to a post

Hello, I’m a new Hugo learner, for now I am using this theme https://themes.gohugo.io/theme/hugo-swift-theme/ which is using a very beautiful logo/animation in its header, and my question is, how can I add same animation logo to the content of one of the posts? which codes do I need to use for that? please help me.
this is the theme files: https://themes.gohugo.io/theme/hugo-swift-theme/

The question is OT in this forum as we offer support for Hugo only, not CSS or other type animations.

I suggest that you ask the theme author in the theme’s issues tracker on GitHub.
