Qlik theme how to use css only on one sheet

[justalkak]

Hi,

I would like to create a custom theme and modify background of first sheet using such a formula:

.qvt-sheet {
background-image: linear-gradient(90deg, #003758 20%, #fff 1%) !important;
}

But the rest of sheets should be white. Is it possible to achieve?

(I know I could modify the sheet using MultiKpi object, but I would like to have this in a theme, not on an object).

There is not a word about my problem under the links so I dont know how to refer to one sheet only.

Apart from that, I regret that using css in Qlik is not well described yet. Is there a place we could find the css class names for Qlik objects? 

Thanks
