CSS If statment?

I'm am editing a shopify site for a client and I came across this code in the css file.

.pass-foot a {
  font-family: "Myriad Pro", "Gill Sans", "Gill Sans MT", Calibri, sans-serif;
  font-style: italic;
  font-size: 16px;
  font-weight: 600;
  **
  color: #fff;
  **
}

I was wondering if anyone has seen anything like this and can explain to me what this if statement is.
