How do I trigger the animation only once

So I have a slideshow built with Bootstrap Carousel, I have a couple items on the first 2 slides, SVGs that animate in. One is a logo drawn, the other fades in. The problem I am running into is the animation starts over when the slide cycles through once. I just want it to trigger on initial load, and then just have the SVGs static. I'm not sure how to do that. I assume JavaScript will be involved to check if the animations have been triggered, but I'm lost on if that's true or otherwise.

I'm guessing these "animations" are actually CSS transitions? If so, one thing you could do is to include a special class in the CSS that will be present when the items are first loaded, but can be removed once they have been shown.

Removing the class can be done with a bit of JavaScript.
