CSS::DOM::Style(3pm) User Contributed Perl Documentation CSS::DOM::Style(3pm) NAME
CSS::DOM::Style - CSS style declaration class for CSS::DOM VERSION
Version 0.14 SYNOPSIS
use CSS::DOM::Style; $style = CSS::DOM::Style::parse(' text-decoration: none '); $style->cssText; # returns 'text-decoration: none' $style->cssText('color: blue'); # replace contents $style->getPropertyValue('color'); # 'blue' $style->color; # same $style->setProperty(color=>'green'); # change it $style->color('green'); # same DESCRIPTION
This module provides the CSS style declaration class for CSS::DOM. (A style declaration is what comes between the braces in "p { margin: 0 }".) It implements the CSSStyleDeclaration DOM interface. CONSTRUCTORS
CSS::DOM::Style::parse( $string ) CSS::DOM::Style::parse( $string, property_parser => $parser ) This parses the $string and returns a new style declaration object. This is useful if you have text from an HTML "style" attribute, for instance. For details on $property_parser, see CSS::DOM::PropertyParser. new CSS::DOM::Style $owner_rule new CSS::DOM::Style owner => $owner_rule, property_parser => $p You don't normally need to call this, but, in case you do, here it is. $owner_rule, which is optional, is expected to be a CSS::DOM::Rule object, or a subclass like CSS::DOM::Rule::Style. METHODS
cssText ( $new_value ) Returns the body of this style declaration (without the braces). If you pass an argument, it will parsed and replace the existing CSS data. getPropertyValue ( $name ) Returns the value of the named CSS property as a string. getPropertyCSSValue ( $name ) Returns an object representing the property's value. (See CSS::DOM::Value.) removeProperty ( $name ) Removes the named property, returning its value. getPropertyPriority Returns the property's priority. This is usually the empty string or the word 'important'. setProperty ( $name, $value, $priority ) Sets the CSS property named $name, giving it a value of $value and setting the priority to $priority. length Returns the number of properties item ( $index ) Returns the name of the property at the given index. parentRule Returns the rule to which this declaration belongs. modification_handler ( $coderef ) This method, not part of the DOM, allows you to attach a call-back routine that is run whenever a change occurs to the style object (with the style object as its only argument). If you call it without an argument it returns the current handler. With an argument, it returns the old value after setting it. property_parser This returns the parser that was passed to the constructor. This module also has methods for accessing each CSS property directly. Simply capitalise each letter in a CSS property name that follows a hyphen, then remove the hyphens, and you'll have the method name. E.g., call the "borderBottomWidth" method to get/set the border-bottom- width property. One exception to this is that "cssFloat" is the method used to access the 'float' property. (But you can also use the "float" method, though it's not part of the DOM standard.) SEE ALSO
