I can't figure out why the buttons won't change colors.

I cant figure out why the buttons won't change background colors. Any help is appreciated.

/* Attribute Selectors ------------- */

.form-contact {
  padding: 20px 24px;
  background: #f4f7f8;

#container {
  max-width: 500px;
  margin: auto;

input[type="email"] {
  background: #fdfee6;


  color: #39add1;
  text-decoration: none;
  border-bottom: 1px dotted;

/* DRY Classes ------------- */

  .br {
  border-radius: .5em;

.avatar {
  display: block;
  margin: 0 auto 2em;

.rounded {
  border-radius: 50%;

.btn {
  cursor: pointer;
  font-size: .875em;
  font-weight: 400;
  color: #fff;
  padding-left: 20px;
  padding-right: 20px;
  text-transform: uppercase;

.btn: hover {
  opacity: .75;

.default {
    background-color: #52bab3;

.error {
  background-color: #ff784f;

Hi Andrew,

I think it's because of a small mistake in your :hover rule. Your code should work if you delete the space between .btn and :hover, and add a } to end the rule;

.btn:hover {
   opacity: .75;
