Hi Nitin,
Please use the CSS below to the custom.css
file.
.banner-item.bg--overlay:before {
opacity: 0.5;
}
You could also increase or reduce the opacity to change the number based on your needs.
Please don’t forget to give us ‘rating and review’ (on https://themeforest.net/downloads ), if you like our template and our support too. It will give us inspiration and make us more ‘happy’ to support.
Best Regards,
ThemeLooks Support Team
