Outlook - Formatting with pass through rectangle with different color

This information is hard to search so pardon me if it is duplicate.

How do I create this background formatting in outlook, where I get a perfect rectangular background ( it is not a table with one row and one column) and you can actually select these just a few of them inside and outside if you know what I mean.

there is another one with a red line on the format and not the text itself. How to do that?
