# CSS::DOM::Constants(3pm)

Constants for CSS::DOM

## NAME

CSS::DOM::Constants - Constants for CSS::DOM

## VERSION

Version 0.17

## SYNOPSIS

```
  use CSS::DOM::Constants ':all';

  # or

  use CSS::DOM::Constants ':rule';

  # or individually

  use CSS::DOM::Constants 'SYNTAX_ERR', ...;
```

## DESCRIPTION

This module provides all the constants used by CSS::DOM.

## EXPORTS

You can import individual constants by name, or all of them with the ':all' tag. In addition, you can specify one of the following tags, to import a group of constants (which can also be imported from other CSS::DOM  modules):

- :exception

  All the constants listed under "EXPORTS" in CSS::DOM::Exception.

- :rule

  All the constants listed under "EXPORTS" in CSS::DOM::Rule.

- :value

  All the constants listed under "CONSTANTS" in CSS::DOM::Value.

- :primitive

  All the constants listed under "CONSTANTS" in CSS::DOM::Value::Primitive.

There is also a `%SuffixToConst` hash which maps dimension suffixes (such as 'px'; all lowercase) to CSSPrimitiveValue type constants (such as `"CSS_PX"`). This is included in the ':all' tag.
