NAME

       CSS::Minifier::XS - XS based CSS minifier

SYNOPSIS

	 use CSS::Minifier::XS qw(minify);
	 $minified = minify($css);

DESCRIPTION

       "CSS::Minifier::XS" is a CSS "minifier"; its designed to remove un-necessary whitespace and comments from CSS files, while also not
       breaking the CSS.

       "CSS::Minifier::XS" is similar in function to "CSS::Minifier", but is substantially faster as its written in XS and not just pure Perl.

METHODS

       minify($css)
	   Minifies the given $css, returning the minified CSS back to the caller.

HOW IT WORKS

       "CSS::Minifier::XS" minifies the CSS by removing un-necessary whitespace from CSS documents.  Comment blocks are also removed, except when
       (a) they contain the word "copyright" in them, or (b) they're needed to implement the "Mac/IE Comment Hack".

       Internally, the minification is done by taking multiple passes through the CSS document:

   Pass 1: Tokenize
       First, we go through and parse the CSS document into a series of tokens internally.  The tokenizing process does not check to make sure
       that you've got syntactically valid CSS, it just breaks up the text into a stream of tokens suitable for processing by the subsequent
       stages.

   Pass 2: Collapse
       We then march through the token list and collapse certain tokens down to their smallest possible representation.  If they're still included
       in the final results we only want to include them at their shortest.

       Whitespace
	   Runs of multiple whitespace characters are reduced down to a single whitespace character.  If the whitespace contains any "end of line"
	   (EOL) characters, then the end result is the first EOL character encountered.  Otherwise, the result is the first whitespace character
	   in the run.

       Comments
	   Comments implementing the "Mac/IE Comment Hack" are collapsed down to the smallest possible comment that would still implement the hack
	   ("/**/" to start the hack, and "/**/" to end it).

   Pass 3: Pruning
       We then go back through the token list and prune and remove un-necessary tokens.

       Whitespace
	   Wherever possible, whitespace is removed; before+after comment blocks, and before+after various symbols/sigils.

       Comments
	   Comments that either (a) are needed to implement the "Mac/IE Comment Hack", or that (b) contain the word "copyright" in them are
	   preserved.  All other comments are removed.

       Symbols/Sigils
	   Semi-colons that are immediately followed by a closing brace (e.g. ";}") are removed; semi-colons are needed to separate multiple
	   declarations, but aren't required at the end of a group.

       Everything else
	   We keep everything else; identifiers, quoted literal strings, symbols/sigils, etc.

   Pass 4: Re-assembly
       Lastly, we go back through the token list and re-assemble it all back into a single CSS string, which is then returned back to the caller.

NAME

       CSS::DOM::Value::List - CSSValueList class for CSS::DOM

VERSION

       Version 0.14

SYNOPSIS

	 # ...

DESCRIPTION

       This module implements objects that represent CSS list property values. It implements the DOM CSSValueList interface.

       You can access the individual elements of the list using the "item" and "length" methods, or by using it as an array ref.

METHODS

       If you need the constructor, it's below the object methods. Normally you would get an object via CSS::DOM::Style's "getPropertyCSSValue"
       method.

   CSSValue Interface
       cssText
	   Returns a string representation of the attribute. Pass an argument to set it.

       cssValueType
	   Returns "CSS::DOM::Value::CSS_PRIMITIVE_VALUE".

   CSSValueList Interface
       item
	   Returns the 'primitive' value at the given index.

       length
	   Returns the number of values in the list.

   Constructor
       You probably don't need to call this, but here it is anyway:

	 $val = new CSS::DOM::Value::List:: %args;

       The hash-style arguments are as follows. Only "values" is required.

       values
	   This must be an array ref containing the individual values to be stored in the list. The individual elements can be value objects or
	   array refs of arguments to pass to "new CSS::DOM::Value::Primitive". E.g.,

	    [
		[type => CSS_PX, value => 20],
		[type => CSS_PERCENTAGE, value => 50],
		[type => CSS_PERCENTAGE, value => 50],
		[type => CSS_PX, value => 50],
	    ]

       css CSS code used for serialisation. This will make reading "cssText" faster at least until the value is modified.

       separator
	   The value separator used in serialisation. This is usually ' ' or ', '. An empty string or "undef" is treated as a space.

       owner
	   The style object that owns this value; if this is omitted, then the value is read-only. The value object holds a weak reference to the
	   owner.

       property
	   The name of the CSS property to which this value belongs. "cssText" uses this to determine how to parse text passed to it. This does
	   not apply to the sub-values of colours, counters and rects, but it does apply to individual elements of a list value.
