/* This will change the value of 1 rem */
html {
  /* font-size: 10px; */ /* But this will cause problems with people who change browser's font size */
  /* Percentage of user's browser font size setting */
  font-size: 62.5%; /* 10px / 16px = 0.625 = 62.5% */
}

Note: rem and em do NOT depend on html font-size in media queries! Instead, 1rem = 1em = 16px.
