@techlady Here is my project in progress. My intent is to mount Pi to back of TV and treat MM as another HDMI input.
As others have said, module writers that stick with the convention of using main.css to format their module make it real easy to format multiple modules by using the appropriate block of main.css and dropping it in custom.css.
Gets sticky when a module author does their own formatting top to bottom.

@sdetweil Luckily, it was the very next one- the default compliments module. I haven’t taken the time to see what is wrong with it. Since everything works now, I’ll leave it disabled until I have time to figure it out.
