right to left animation on masonry titles

Hello,

Im trying to modify the loading of the Masonry (blog) post titles. I have the animation deactivated since its a little too much movement for the brand. However, I would like to simply animate the title in from right to left, at the same speed as the “right to left” animation that is already in place for columns. Is it possible to add css to the headline style so headlines can appear in viewport from the right?

I’ve tried variations of the following with no luck:
#top .av-caption-style-overlay .av-masonry-entry .av-masonry-entry-title {
-webkit-animation: avia-rtl 0.8s 1 cubic-bezier(0.175, 0.885, 0.320, 1.275);
animation: avia-rtl 0.8s 1 cubic-bezier(0.175, 0.885, 0.320, 1.275);
}
