selector-pseudo-class-parentheses-space-inside

Require a single space or disallow whitespace on the inside of the parentheses within pseudo-class selectors.

input:not( [type="submit"] ) {}
/**      ↑                 ↑
 * The space inside these two parentheses */

The fix option can automatically fix the problems reported by this rule, leaving any comment inside the parentheses where it is.

An empty argument, as in input:not() or input:not(,[type="submit"]), has no inside to space out; where whitespace stands at one, the whole list is passed over. An end of the parentheses whose whitespace is the line break closing an inline comment is passed over too.

Options

string: "always"|"never"

"always"

There must always be a single space inside the parentheses.

The following patterns are considered problems:

input:not([type="submit"]) {}

input:not([type="submit"] ) {}

The following patterns are not considered problems:

input:not( [type="submit"] ) {}

"never"

There must never be whitespace on the inside the parentheses.

The following patterns are considered problems:

input:not( [type="submit"] ) {}

input:not( [type="submit"]) {}

The following patterns are not considered problems:

input:not([type="submit"]) {}
