To resolve this, the ask in the issue

1. Buttons to be styled with rectangular outline.
2. Tags to be styled with solid background.

I support this, also the changes are looking good.

However, I feel like there should be a py-1 added to some of the tags which are being converted to solid.

in the above 👆 example you can see that lightMeasured Message ID tags which you have made solid appear to be thinner than format: date-time

This is my opinion, Please let me know what you think about this.
