Can you share what code you already have so we know what you're really trying to do?

Are you talking about tabs like the ones found on YouTube?

If so, it looks like taking CSS from this Codepen will answer your question if you are in fact asking how to get tabs like the ones shown above. Just look around and see what you need to do to modify it to your liking and then adjust your code. Click on the link and go to #13 (won't let me post a Codepen without code, but scroll down to #13 and there's your answer) https://csshint.com/css-tabs/

I searched "animated css tabs" on Google, went to the first result and scrolled down to #13 to find this.
