Issues with the productpage Woocommerce (Theme Niche)

It happens just, when the page is fullscreen. Not when it's mobile.

Hi there,

the Niche site adds a stacked Gallery to the desktop view using a Hook element.
It looks like you have disabled that.

Which means you also to remove the related CSS - go to Customizer > Additional CSS.
Delete this:

/* Stacked Gallery for desktop and sticky summary */
@media (min-width: 768px) {
    .woocommerce-product-gallery {
        display: none;
    }

    .woo-sumamry-wrap {
        display: grid;
        grid-template-columns: 60% 40%;
        grid-template-rows: auto;
        margin-bottom: 80px;
    }

    .woo-gallery-stack {
        grid-column: 1;
        grid-row: 1 / 3;
    }

    .woo-gallery-stack img {
        margin-bottom: 20px;
    }

    .woocommerce-tabs {
        grid-column: 1;
    }

    .woocommerce div.product div.summary {
        grid-column: 2;
        grid-row: 1;
        margin-left: 80px;
        position: -webkit-sticky;
        position: sticky;
        top: 105px;
        bottom: 100px;
        padding-right: 80px;
    }

    .single-product span.onsale {
        position: absolute;
        top: 0;
    }
}

Thank you so much! Problem solved. :D

You're welcome
