Changing font-family for placeholder

In case someone want the placeholders selectors for all browsers :

.mainLoginInput::-webkit-input-placeholder {
  font-family: 'myFont', Arial, Helvetica, sans-serif;
}

.mainLoginInput:-ms-input-placeholder {
  font-family: 'myFont', Arial, Helvetica, sans-serif;
}

.mainLoginInput:-moz-placeholder {
  font-family: 'myFont', Arial, Helvetica, sans-serif;
}

.mainLoginInput::-moz-placeholder {
  font-family: 'myFont', Arial, Helvetica, sans-serif;
}
