I could not see this covered in the regex sticky

I want to write a single find/replace that will zap all of

line-height:1.2;
line-height:1.3
line-height:1.2em;
line-height:1.2em
line-height: 1.2;
line-height: 1.3
line-height: 1.2em;
line-height: 1.2em

i.e. remove all fixed line heights in range 1-2 em from CSS.
NBthey may or may not have an explicit em & they may nor may not have a space after the first colon, and they may or may not have a trailing ;

I've got this far:
line-height:\s?1\.\d
I can't seem to also capture the last bits ?

update:
this works but it feels like a cheat, because it just grabs everything up to the next bit of white space. you could probably write a valid CSS with no white space between statements.
line-height:\s?1\.\d(.*)\s

Anyway, I'd like to learn the proper way to find and include zero or one instance of a given string
