code inside brackets, including KWI

I couldn’t find any reference to what KWI means, as I was trying to educate myself on what it designates. So, one, what does that mean?

Because, two, my understanding is anything inside brackets with a star isn’t active code (as follows in my CSS). Am I right?:

body {
	/*KWI font-size: 62.5%; *//* Resets 1em to 10px */

	font-family: Helvetica, Verdana, Arial, Sans-Serif;

Because, three: I want to change the font-size to larger than 1em, or 10px, but having a hard time understanding where to do that. When, as a test, I added font-size:1.15em to the following, it had no effect on the masterpage text.

}
.voltrek_masterpage p {
  padding:0px;
  margin:0px;
  margin-top:8px;
  margin-bottom:8px;
  color:#000000;
  line-height: 19px;
}

So, I laid out my thought process, because I’m not thinking this through correctly. Can you help?
