Classes for btn

Where did you define the classes for btn--default, btn--success, btn--error, btn--warning and btn--info?

Sorry lost you on this part. We may have done this on previous lessons but I can't find it.

Hi Bruno,

btn-- styles are defined in _main.scss and _extends.scss. Colors are defined in _config.scss

/* _main.scss */
.btn {
    @include bg-colors($ui-colors);
}

[class^="btn--"] {
  @extend %btn;
  margin-bottom: em(20px, 14px); 
  width: auto;
  display: inline-block;
  margin-right: em(15px, 14px);
} 

/* _extends.scss */

%btn {
  padding: 15px 30px;
  border: 0;
  border-radius : $br--default;
  color: $white;
  text-transform: uppercase;
  font-size : em(14px);
  font-weight: $font-weight--medium;
  transition: opacity $trns-duration;
  display: block;
  &:hover {
    opacity: .75;
  }
  &:active {
    opacity: initial;
  }
}

/* _config.scss */

$fountain-blue  : #52bab3;
$emerald        : #5ece7f;
$sunglo         : #e67478;
$coral          : #ff784f;
$purple-majesty : #9279c3;
$scooter        : #39add1;

// UI Colors
$ui-colors: (
    default : $fountain-blue,
    success : $emerald,
    error   : $sunglo,
    warning : $coral,
    info    : $purple-majesty
);

Think thats all of them.

Hope this helps :)

EDIT:

Also see _utilities.scss for the bg-colors mixin

// Mixins

@mixin bg-colors($map) {
    @each $theme, $color in $map {
        &--#{$theme} {
            background-color: $color;    
        }
    }
}
