Hi @DeeDesign,
That slide up effect is not quite possible with a custom CSS because we can not apply an opacity on the background. But we can have an effect that is close to that with the help of background-position and CSS transition property.
You can update the given CSS code to this:
#tab-e1206-13,
#tab-e1206-14 {
background-position: 0 -100%;
background-repeat: no-repeat;
background-size: cover;
transition: background-position 1.5s ease;
}
#tab-e1206-13 {background-image: url(https://www.barbsfishandchips.com/wp-content/uploads/2019/07/clams.jpg);}
#tab-e1206-14 {background-image: url(https://www.barbsfishandchips.com/wp-content/uploads/2019/07/fishandchips.jpg);}
#tab-e1206-13:hover,
#tab-e1206-13.x-active,
#tab-e1206-14:hover,
#tab-e1206-14.x-active {
background-position: center;
}
.x-acc-header.x-active .x-acc-header-content {
color: #fff !important;
}
Please be reminded that further customization from here falls outside of the scope of support that we can offer.
You can find the proper CSS code selector using the Chrome browser Developer Toolbar
For the CSS code itself, I suggest that you get started with this tutorial
With regards to the radius, you can set that under the “Items” tab of the Accordion element.
Hope it helps,
Cheers!
