# lightningcss-plugins

## pxToRem

Convert pixel values to rem values.

```ts

import {code} from 'lightningcss'

import {pxToRem} from 'lightningcss-plugins'

interface PxToRemOptions {

  /** Represents the root element font size (default: 16) */

  rootValue?: number

  /** The decimal numbers to allow the REM units to grow to (default: 5) */

  unitPrecision?: number

  /** Set the minimum pixel value to replace (default: 0) */

  minPixelValue?: number

}

const {code} = transform({

  visitor: pxToRem(/* options */),

  filename: 'test.css',

  code: Buffer.from(`

    body {

      font-size: 16px;

      max-width: 960px;

    }

  `)

})

```

Result:

```css

body {font-size: 1rem; max-width: 60rem}

```

## suffixes

Append nested type selectors to the parent selector like is the case in scss/less.

As long as the outer selector ends with an alphanumeric name (like class, ID,

and element selectors), you can use the parent selector to append additional text.

```ts

import {code} from 'lightningcss'

import {suffixes} from 'lightningcss-plugins'

const {code} = transform({

  visitor: suffixes,

  filename: 'test.css',

  code: Buffer.from(`

    .accordion {

      max-width: 600px;

      &__copy {

        display: none;

        color: gray;

        &--open {

          display: block;

        }

      }

    }

  `)

})

```

Result:

```css

.accordion {max-width: 600px}

.accordion__copy {display: none; color: gray}

.accordion__copy--open {display: block}

```

Note: this means it is no longer possible to use nesting to specify the element:

```css

.class {&div {color: red}}

/* Will transform to: */

.classdiv {color: red}

/* But you can use is: */

.class {&:is(div) {color: red}}

/* Which will yield: */

.class:is(div) {color: red}

```
