NAME
    CSS::Simple - Interface through which to read/write/manipulate CSS files
    while respecting the cascade order

SYNOPSIS
     use CSS::Simple;

     my $css = new CSS::Simple();

     $css->read({ filename => 'input.css' });

     #perform manipulations...

     $css->write({ filename => 'output.css' });

DESCRIPTION
    Class for reading, manipulating and writing CSS. Unlike other CSS
    classes on CPAN this particular module focuses on respecting the cascade
    order while providing a common sense API through which to manipulate the
    parsed rules.

CONSTRUCTOR
    new ([ OPTIONS ])
        Instantiates the CSS::Simple object. Sets up class variables that
        are used during file parsing/processing.

METHODS
    read_file( params )
        Opens and reads a CSS file, then subsequently performs the parsing
        of the CSS file necessary for later manipulation.

        This method requires you to pass in a params hash that contains a
        filename argument. For example:

        $self->read_file({filename => 'myfile.css'});

    read( params )
        Reads css data and parses it. The intermediate data is stored in
        class variables.

        This method requires you to pass in a params hash that contains
        scalar css data. For example:

        $self->read({css => $css});

    write_file()
        Write the parsed and manipulated CSS out to a file parameter

        This method requires you to pass in a params hash that contains a
        filename argument. For example:

        $self->write_file({filename => 'myfile.css'});

    write()
        Write the parsed and manipulated CSS out to a scalar and return it

    get_properties( params )
        Get a hash that represents the various properties for this
        particular selector

        This method requires you to pass in a params hash that contains
        scalar css data. For example:

        $self->get_properties({selector => '.foo'});

    check_selector( params )
        Determine if a selector exists within the stored rulesets

        This method requires you to pass in a params hash that contains
        scalar css data. For example:

        $self->check_selector({selector => '.foo'});

    add_selector( params )
        Add a selector and associated properties to the stored rulesets

        In the event that this particular ruleset already exists, invoking
        this method will simply replace the item. This is important - if you
        are modifying an existing rule using this method than the previously
        existing selectivity will continue to persist. Delete the selector
        first if you want to ignore the previous selectivity.

        This method requires you to pass in a params hash that contains
        scalar css data. For example:

        $self->add_selector({selector => '.foo', properties => {color =>
        'red' }});

    add_properties( params )
        Add properties to an existing selector, preserving the selectivity
        of the original declaration.

        In the event that this method is invoked with a selector that
        doesn't exist then the call is just translated to an add_selector
        call, thus creating the rule at the end of the ruleset.

        This method requires you to pass in a params hash that contains
        scalar css data. For example:

        $self->add_selector({selector => '.foo', properties => {color =>
        'red' }});

    delete_selector( params )
        Delete a selector from the ruleset

        This method requires you to pass in a params hash that contains
        scalar css data. For example:

        $self->delete_selector({selector => '.foo' });

    delete_property( params )
        Delete a property from a specific selectors rules

        This method requires you to pass in a params hash that contains
        scalar css data. For example:

        $self->delete_property({selector => '.foo', property => 'color' });
