Another example: I have set the backgrounds of my Computing cat-note as follows:
The Computing category webpage will display its truncated posts as a continuous sheet. Its background will be a fixed white circuitboard image. The image has an Alpha channel and has been placed atop a rich #669, which will provide good contrast. And it has been stretched to fit horizontally.
The options tell us: there will be a fixed IMAGE, tinted some COLOR, FITTED horizontally, and all of this is BEQUEATHED to its children.
Here is the exported cat-note:
And here is the Key Attribute Table from one of its children:
The children of the Computing category page will have the same image and color, but with the Main Text Area as a CARD with a pure white background.
