Help in setting the slideshow

Hi,
I m trying to reduce the height of the slideshow in this theme without success.
I ve used this setting in override.css but no success :

.gk-is-wrapper-gk-storefront {
height: 400px;
}

@media (max-width: 1040px) {
.gk-is-wrapper-gk-storefront {
height: 250px;
}
}

@media (max-width: 800px) {
.gk-is-wrapper-gk-storefront {
height: 180px;
}
}
Any help is much appreciated
Thanks in advance

Hello,

Could you please provide me with a URL to your website, either here or via PM (click the “Private Message” text underneath my avatar) so that I may analyze it? It is a lot easier for us to diagnose issues when we have a live site to examine.
