**Bare essentials CSS prefixing helpers in less than 1KB 🌈**

Currently supports prefixing properties for most browsers as it makes sense.

[See `SUPPORT.md` for more information on which prefixes and transformations have been omitted.](./SUPPORT.md)

The API is fairly straightforward and only consists of two functions, `prefixProperty` and `prefixValue`.

```js

prefixProperty('margin'); // 0b000

prefixProperty('appearance'); // 0b110

prefixValue('color', 'palevioletred'); // 'palevioletred'

prefixValue('position', 'sticky'); // '-webkit-sticky, sticky'

```

`prefixProperty` returns a bitmap depending on which prefix should be

applied:

- `0b001` stands for `-ms-`

- `0b010` stands for `-moz-`

- `0b100` stands for `-webkit`

These are combined using a binary OR, so an example usage of the

`prefixProperty` helper may look like the following:

```js

const prefix = (prop, value) => {

  const flag = prefixProperty(prop);

  let css = `${prop}: ${value};\n`;

  if (flag & 0b001) css += `-ms-${css}`;

  if (flag & 0b010) css += `-moz-${css}`;

  if (flag & 0b100) css += `-webkit-${css}`;

  return css;

};

```

Additionally `prefixValue` can accept full declarations to avoid

having to apply it before concatenation, which can be useful in case

you're trying to minimise string operations:

```js

const declaration = 'position: sticky';

prefixValue(declaration, declaration); // 'position: -webkit-sticky, sticky'

```
