Warning

This rule is deprecated and will be removed in the future. See the migration guide.

Require a single space or disallow whitespace on the inside of the parentheses of functions.

a { transform: translate( 1, 1 ); }

 * The space inside these two parentheses */

The fix option can automatically fix all of the problems reported by this rule.

Options​

string: "always"|"never"|"always-single-line"|"never-single-line"

"always"​

There must always be a single space inside of the parentheses.

The following patterns are considered problems:

a { transform: translate(1, 1); }
a { transform: translate(1, 1 ); }

The following patterns are not considered problems:

a { transform: translate( 1, 1 ); }

"never"​

There must never be whitespace on the inside of the parentheses.

The following patterns are considered problems:

a { transform: translate( 1, 1 ); }
a { transform: translate(1, 1 ); }

The following patterns are not considered problems:

a { transform: translate(1, 1); }

"always-single-line"​

There must always be a single space inside the parentheses of single-line functions.

The following patterns are considered problems:

a { transform: translate(1, 1) }
a { transform: translate(1, 1 ) }

The following patterns are not considered problems:

a { transform: translate( 1, 1 ) }
a { transform: translate(1,
  1) }
a {
  transform: translate(
    1,
    1
  )
}

"never-single-line"​

There must never be whitespace inside the parentheses of single-line functions.

The following patterns are considered problems:

a { transform: translate( 1, 1 ) }
a { transform: translate(1, 1 ) }

The following patterns are not considered problems:

a { transform: translate(1, 1) }
a { transform: translate( 1,
  1) }
a {
  transform: translate(
    1,
    1
