Control poster position, start of the project

Hi.

Thanks to some of the contributions of experts in the forum, I have been able to eliminate in the project the focus, initial play, including the instruction (*: aten {

    scheme: 0;

    }

But now the poster image appears to me displaced vertically, it is positioned above. In which part of the file "CPLibraryAll" I can control the height of the poster.

Thank you
