Re transparency - there are several threads in the forum. Spacers should be same colour as the card "background"

> As subject, I want a transparent background on md-card (ie the group), somehow I am not able to force it, I see body.nr-dashboard-theme md-content md-card getting a background color. Can I set it to transparent somehow using jquery once template/tab is loaded ? I am having a hard time to grasp which class to set to transparent. Note I only want this on 1 particular tab, not on all.

> Hi! I have set my back with a template node with this body { background-image: url("http://escapec001.local/test/test.jpg"); } now the outline of the screen shows the image. but the node covers it in black is it possible to set the background of the template node transparant so you see the background image?
