This parser understands simple CSS and comes with a basic CSS syntax checker.

```

go get github.com/napsy/go-css

```

Example usage:

```go

import "github.com/napsy/go-css"

ex1 := `rule {

	style1: value1;

	style2: value2;

}`

stylesheet, err := css.Unmarshal([]byte(ex1))

if err != nil {

	panic(err)

}

fmt.Printf("Defined rules:\n")

for k, _ := range stylesheet {

	fmt.Printf("- rule %q\n", k)

}

```

You can get a CSS verifiable property by calling ``CSSStyle``:

```go

style, err := css.CSSStyle("background-color", styleSheet["body"])

if err != nil {

	fmt.Printf("Error checking body background color: %v\n", err)

} else {

	fmt.Printf("Body background color is %v", style)

}

```

Most of the CSS properties are currently not implemented, but you can always write your own handler by writing a ``StyleHandler`` function and adding it to the ``StylesTable`` map.
