Change line-height in CSS for comments

[MulletMidget]

I don't know if this is template related maybe (I use RocketThemes SolarSentinel template) but the entered comments text lines are to tight and are kind of hard to read.
I know I can change this by adding/altering the "line-height" in the CSS-file.
But where exactly do I change this?

In components/com_jcomments/tpl/default/style.css or in my templates template.css?
I guess the first one.
But there seem to be a dozen of "line-height"-entries in style.css, so it would take me the whole day to guess.
So which one is the one I need to change for the comments line spacing?

You can add your own line-height in style:

Code: (css)

#comments .comment-body {color: #777;margin: 6px 0 0;padding:0 0 2px}

This style is applied to comment's text block...

Thank you!
Worked like a charm.
I added "line-height: 150%" and now the text is much easier to read.
