## API
### perfectionist.process(css, [options])
#### css
Type: `string`
*Required option.*
Pass a CSS string to beautify it.
#### options
##### cascade
Type: `boolean`
Default: `true`
Set this to `false` to disable visual cascading of vendor prefixed properties.
Note that this transform only applies to the `expanded` format.
```css
/* true */
h1 {
-webkit-border-radius: 12px;
border-radius: 12px;
}
/* false */
h1 {
-webkit-border-radius: 12px;
border-radius: 12px;
}
```
##### colorCase
Type: `string`
Default: `lower`
Set either `lower` or `upper` to transform hexadecimal colors to the according case.
```css
/* lower */
p { color: #C8C8C8 }
/* upper */
p { color: #c8c8c8 }
```
##### colorShorthand
Type: `boolean`
Default: `true`
Set this to `true` to shorten hexadecimal colors.
```css
/* true */
p { color: #fff }
/* false */
p { color: #ffffff }
```
##### format
Type: `string`
Default: `expanded`
Pass either `vertical-align`, `expanded`, `compact` or `compressed`. Note that the `compressed`
format only facilitates simple whitespace compression around selectors &
declarations. For more powerful compression, see [cssnano].
##### indentSize
Type: `number`
Default: `4`
This number will be used as a basis for all indent levels, using the `expanded`
format.
##### trimLeadingZero
Type: `boolean`
Default: `true`
Set this to `true` to trim leading zero for fractional numbers less than 1.
```css
/* true */
p { line-height: .8 }
/* false */
p { line-height: 0.8 }
```
##### trimTrailingZeros
Type: `boolean`
Default: `true`
Set this to `true` to traim trailing zeros in numbers.
```css
/* true */
div { top: 50px }
/* false */
div { top: 50.000px }
```
##### maxAtRuleLength
Type: `boolean|number`
Default: `80`
If set to a positive integer, set a maximum width for at-rule parameters; if
they exceed this, they will be split up over multiple lines. If false, this
behaviour will not be performed. Note that this transform only applies to
the `expanded` format.
##### maxSelectorLength
Type: `boolean|number`
Default: `80`
If set to a positive integer, set a maximum width for a selector string; if
it exceeds this, it will be split up over multiple lines. If false, this
behaviour will not be performed. Note that this transform is excluded from the
`compressed` format.
##### maxValueLength
Type: `boolean|number`
Default: `80`
If set to a positive integer, set a maximum width for a property value; if
it exceeds this, it will be split up over multiple lines. If false, this
behaviour will not be performed. Note that this transform only applies to
the `expanded` format.
##### sourcemap
Type: `boolean`
Default: `false`
Generate a sourcemap with the transformed CSS.
##### syntax
Type: `string`
Specify `scss` if you would like to also format SCSS-style single line comments.
This loads the [postcss-scss](https://github.com/postcss/postcss-scss) plugin.
##### zeroLengthNoUnit
Type: `boolean`
Default: `true`
Set this to `true` to trim units after zero length.
```css
/* true */
div { padding: 0 }
/* false */
div { padding: 0px }
```
