at-else-closing-brace-newline-after

Require or disallow a newline after the closing brace of @else statements.

@if (@a == 0) {

} @else if (@a == 1){ }
@else { }             ↑
/**     ↑             ↑
 * The newline after these braces */

This rule might have conflicts with stylelint's core rule block-closing-brace-newline-after if it doesn't have "ignoreAtRules": ["else"] in a .stylelintrc config file. That's because an @else { ... } statement can be successfully parsed as an at-rule with a block. You might also want to set "ignoreAtRules": ["else"] for another stylelint's core rule - at-rule-empty-line-before that could be forcing empty lines before at-rules (including @elses that follow @ifs or other @elses).

This rule doesn't have usual "always" and "never" main option values, because if you don't need special behavior for @if and @else you could just use block-closing-brace-newline-after set to "always" or any other value.

Options

string: "always-last-in-chain"

"always-last-in-chain"

There must always be a newline after the closing brace of @else that is the last statement in a conditional statement chain (i.e. has no @else right after it). If it's not, there must not be a newline.

The following patterns are considered warnings:

a {
  @if ($x == 1) {
    // ...
  } @else {
    // ...
  } width: 10px; // No @else after, so should have a newline
}

@if ($x == 1) {
  // ...
} @else if { } // Has @else after it, so shouldn't have a newline
@else { }

The following patterns are not considered warnings:

a {
  @if ($x == 1) {} @else {}
  width: 10px;
}

a {
  @if ($x == 1) {
    // ...
  } @else if {
    // ...
  } @else {}

  width: 10px;
}

a {
  @if ($x == 1) { } @else if { }@else { }

  width: 10px;
}
