Hi there,
Unfortunately, the Modern Grid generated code of the M.E.C. plugin does not have any ID or Class that you can use. But I suggest that you use a position based solution for this case. Kindly add the CSS code below to X > Launch > Options > CSS:
.mec-event-grid-modern .row:nth-child(1) .col-md-4:nth-child(1) .mec-event-article {
background: green;
}
.mec-event-grid-modern .row:nth-child(1) .col-md-4:nth-child(2) .mec-event-article {
background: yellow;
}
.mec-event-grid-modern .row:nth-child(1) .col-md-4:nth-child(3) .mec-event-article {
background: red;
}
.mec-event-grid-modern .row:nth-child(2) .col-md-4:nth-child(1) .mec-event-article {
background: blue;
}
.mec-event-grid-modern .row:nth-child(2) .col-md-4:nth-child(2) .mec-event-article {
background: orange;
}
.mec-event-grid-modern .row:nth-child(2) .col-md-4:nth-child(3) .mec-event-article {
background: purple;
}
Depending on the color of the background you will see which section of the CSS code is for which event so that you can add proper background images instead of the colors in the CSS code.
Thank you.
