How to fix transparency in product sliders / featured products on home page?

by

You just have to apply white (#FFFFFF) background-color to the slider item because by default it has transparent background color.

Please use below CSS

.owl-item {
    background-color: #FFFFFF;
}

Please note that this should be placed at the bottom so it gets high priority.

If it does not work can you please provide link of your page?

Thank you.
