responsive property doesn't seem to have an effect. In desktop version it is working fine, but on mobile device it still shows the same number of items as in desktop.

 $('.owl-carousel').owlCarousel({
    loop:true,
    margin:5,
    nav:false,
    responsiveClass:true,
    autoplay:true,
    autoplayTimeout:2500,
    responsive:{
        0:{
            items:1,
        },
        600:{
            items:2
        },
        1000:{
            items:4
        }
    }
})

• javascript
• jquery

• Do you have responsive meta tag in head of page: <meta name="viewport" content="width=device-width, initial-scale=1.0">? – prettyInPink Commented Nov 19, 2021 at 8:25
• yes I did it but still doesn't work – shuvo Commented Nov 19, 2021 at 9:10

These are two ways I found:

1-you have to set minimum-scale and maximum-scale of viewport meta tag:

<meta name="viewport"
    content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">

2- Add following option to js:

responsiveBaseElement: 'body'

Just in case, maybe you did not include responsive meta tag:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Seems to be working fine with the code you added, maybe some css that is overwriting this somehow?

 $('.owl-carousel').owlCarousel({
    loop:true,
    margin:5,
    nav:false,
    responsiveClass:true,
    autoplay:true,
    autoplayTimeout:2500,
    responsive:{
        0:{
            items:1,
        },
        600:{
            items:2
        },
        1000:{
            items:4
        }
    }
});

.owl-carousel {
    margin: 2rem 0;
}

.owl-carousel .item {
    height: 10rem;
    background: #4DC7A0;
    padding: 1rem;
}

.owl-carousel .item h4 {
    color: #FFF;
    font-weight: 400;
    margin-top: 0rem;
}
