Icon colour and button sizing issues

image Hi folks, I'm new to raspberry pi, node-red and Angular JS so this is a steep learning curve for me!

My objective:
I am building on Robert Lando's Security Pin Dialog UI Template for Node-Red-Dashboard to create a touch screen interface on a 5" HDMI LCD with resistive touch overlay, driven by a Pi zero.

The problem:
I'm using dashboard template widgits to create the "touch" buttons but I'm having some issues.

  1. The icon - I can't work out how to get the icon colour set to white. It appears to default to
    #0099ff which I think is the default colour for dashboard widgits.

  2. Using the layout tab in the dashboard panel to set the size of the "button" (16 x 9) appears to be over-ridden by some thing because the buttons rendered are 16 units wide but only one unit high.

I would like to achieve the following:
Doorbell button
Touch button size = 16x9 (Dashboard grid)
Touch button colour = #0099ff
Icon size = 80px
Icon colour = white
Entry button
Touch button size = 16x3 (Dashboard grid)
Touch button colour = #0099ff
Icon size = 80px
Icon colour = white
