I tried the following with the stylesheet and <input/> yet the color of the placeholder still has not changed and stays at the default color. Am I doing it incorrectly?
my css stylesheet:
#input-field {
  background-color: rgba(255,255,255,0.1);
  border: 0;
  border-radius: 5px;
  width: 150px;
  height: 40px;
  padding: 12px;
  box-shadow: none;
  color: rgba(255,255,255,0.8);
}
:-webkit-input-placeholder { /* WebKit, Blink, Edge */
    color:    blue;
}
:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
   color:    blue;
   opacity:  1;
}
::-moz-placeholder { /* Mozilla Firefox 19+ */
   color:    blue;
   opacity:  1;
}
:-ms-input-placeholder { /* Internet Explorer 10-11 */
   color:    blue;
}
And my <input/>:
  <input
    className="form-control"
    id="input-field"
    placeholder='Change This Color'
  />
