I am using OwlCarousel 2.3.4 and I have the carousel working but it seems to be ignoring the coverproperty set in my CSS so it is displaying all images side by side rather than as a cover.
I have created a CodePen with my code (I have removed most of the content to keep it small but the Owl Carousel issue is still there) - CodePen
Initially, owl carousel shows 3 items. If you want to customize the item, you can just add an item property where you have initialized the carousel.
something like this one example--
` $(document).ready(function(){
$(".owl-carousel").owlCarousel({
loop: true,
autoplay: true,
items: 1
});
});`
