Why doesn't the Swiper slider hide its inactive elements?

Question

css

What could I have done wrong or what properties are written incorrectly that the Swiper slider displays inactive slides behind the page.

<div class="reviews" id="rev">
        <div class="container">
            <div class="swiper-container">
                <div class="swiper-wrapper">
                    <div class="swiper-slide">

You must style one of the nearest parent elements. In your case, for a block with the reviews class
overflow: hidden
