Thank you so much for your comment!
If you’re using the timer you shouldn’t encounter serious issues. I’ve tried with 5000, 6000 and up and it’s working fine. Perhaps you need to adjust the animation-delay property in the CSS. If I go lower than 4000 I’ll have to revise the value of the animation-delay property: as it stands, the entire animation of all three elements in the slider takes 3 seconds, therefore any value lower than this in the timer has a negative effect on the resulting animation.
What’s exactly not working on your end? Could you please post a link to your code?
Cheers!
