Details

Separate rule, function, and mixin declarations with empty lines.

Bad: no lines separating blocks

p {
  margin: 0;
  em {
    ...
  }
}
a {
  ...
}

Good: lines separating blocks

p {
  margin: 0;

  em {
    ...
  }
}

a {
  ...
}

By default, this will ignore single line blocks, so you can write:

.icon-chevron-up    { &:before { content: "\e030"; } }
.icon-chevron-down  { &:before { content: "\e031"; } }
.icon-chevron-left  { &:before { content: "\e032"; } }
.icon-chevron-right { &:before { content: "\e033"; } }

Configuration Option	Description
`ignore_single_line_blocks`	Don't enforce for single-line blocks (default true)
