Link color - yihui/xaringan GitHub Wiki

Link color can be changed inside the a, a > code css chunk:

a, a > code {
  color: #FF1B70; /*default: rgb(249, 38, 114); || sets color of links */
  text-decoration: none; /* turns off background coloring of links */
}

By default, all links have a grey background - this can be turned off by using text-decoration: none.
