.message, .error { ... } .message.alert, .error.alert { ... }
.error { ... } Output: SCSS: .message { ... &.alert { ... } } .error { ... @extend .message; }
Placeholder Selectors

.i-red { color: red; } .i-blue { color: blue; }
Output: SCSS: @mixin i($color) { @if $color == red { color: red; } @else { color: blue; } } .i-red { @include i(red); } .i-blue { @include i; }
Error Reporting
First Variables. Then Mixins. Then @extend. Then more advanced stuff!
Start with baby steps
Stay organized
Clarity is beautiful.
Clarity > Brevity
If you’re nesting more than 3 levels deep, you’re probably
doing something wrong.
