Hello @Saravanan,
We are sorry that you are getting trouble regarding the image size. In an updated version 1.0.1, we have added the same height script for slider items. Now we realize that after changes, it needs more than 650px height image. We have updated the image size to 1920px (width) and 850px (height) in the new version (1.0.2) and it’s now available.
In your recent case, please update the new version and we are highly recommended to upload new image size ie: 1920px X 850px. If it is not possible, then you can do with CSS. It will fix those blank spaces with little Zooming the image. Please refer below steps:
Go to Dashboard > Appearance > Customize > Additional CSS and paste below CSS code.
.block-slider .slide-item {
-webkit-background-size: cover !important;
-moz-background-size: cover !important;
-ms-background-size: cover !important;
-o-background-size: cover !important;
background-size: cover !important;
}
Best Regards.
