inline-css 0.0.3

Embed CSS directly in your Rust code
Documentation
# inline-css
Inline CSS directly into your Rust code.

## Example
``` rust
use inline_css::css;

fn main() {
    let css = css! {
        h1 {
            color: red;
        }
    };
    
    println!("{css}");
}
```

## Syntax issues
### `margin: 10em;`
This doesn't work because Rust expects an exponent after the `e`.
The workaround is to write `10m`, which the macro implicitly converts to `10em`.

### `padding: calc(10 - 1);`
Unsupported, use `padding: {10 - 1};` instead.

### `color: #0000ef;`
Impossible to parse, use `color: #0xff00ff;` instead.

### `color: #0x0ff;`
Is interpreted as `color: #0x0000ff;`, please use `color: #0x00ffff;` instead.

## TODO
- [ ] Documentation
- [ ] Parse `h1::after {}`
