Two JSON questions regarding formatting a Tile View for a SharePoint list

Beth_Culpepper 

You could try this. I have made some slight changes and I believe it should make the column headers bold, black and slightly bigger.

It should also change the color of the border around the tile. 

As I am far from an expert, I hope it works to that extent. I'm not sure how to make the tile-border bold yet (I'm not usually using tiles). 

I have pulled the particular expressions from this website:

https://zerg00s.github.io/sp-modern-classes/ (zerg00s.github.io)

You can, for example, pick a different color for the border by looking through the (many) examples and finding a similar expression for a different color. I hope that makes sense.

Im also attaching a (low quality) screenshot where I have highlighted where exactly I have made changes. The first one describes the border color, the other three each format the column title.

Hope it helps!
