Hi @chugs
Slide-ins don’t have such overlay. A bit of CSS can “visually” simulate it though:
.hustle-slidein {
background:rgba(55,55,55,0.5);
}
You’ll want to adjust the color (parameters in rgba are, accordingly: Red, Green, Blue color values and the last one is opacity – transparency) but note please that, unlike with popup, this overlay will not prevent clicking on elements on the page.
If you want to use image instead of semi-transparent color, you can use this version of above CSS
.hustle-slidein {
background:rgba(55,55,55,0.5);
background:url('FULL_URL_TO_IMAGE_HERE');
background-size:cover;
}
Note: you would need to add this as custom CSS to the site, on “site”/theme level rather than directly in custom CSS of the slide-in.
Kind regards,
Adam
