[Sugarcube] Text Align in css just straight up doesn't work

Ok so I have been playing around with css and while I was testing some stuff I found out text-align does absolutely nothing. I tried making a simple custom css

#testingstyle
{
	color:red;
	text-align:center;
}

just made the text red, still left aligned. Then I just straight up put

@@text-align:center;this should be in the center@@

and again it did nothing.

I looked it up and all I saw was setting the alignment for all passages which is not what I want. I want to be able to change the alignment on the fly.
