lightbox blur and increased transparency effect for individual images

Good afternoon,

I wondered if there is a way to blur the background and increase the opacity of a lightbox when clicking on an individual image (not the gallery lightbox).

I'm trying to do this for the pages https://www.gabedoubleglazing.com.au/double-glazed-doors and https://www.gabedoubleglazing.com.au/double-glazed-windows, and more specifically the individual colours in the sections 'colour options'.

Many thanks,
Arnoud
 

Thank you, this works great for the opacity, which I put at 0.7.

Is there a way to 'blur' the background when the lightbox is showing, for visual effect?

Try this code

body#collection-655c1488e98bfc546f524d06.sqs-lightbox-open div#siteWrapper {
    filter: blur(3px);
}

Works like a charm, thanks !!
