Add Background color in Category meta

Hi there,

Where is the category meta you are referring to here?

I’m only seeing this in single posts:

Sorry my old data removed.

Mainly i want to add category in single post before title. ( Only category meta )

Like this : Link

I’ll create new topic on it after adding category meta.

Sounds good ??
