Local copy of validators @type HTMLPurifier_AttrDef[].
- Note
- If we moved specific CSS property definitions to their own classes instead of having them be assembled at run time by CSSDefinition, this wouldn't be necessary. We'd instantiate our own copies.
The documentation for this class was generated from the following file:
- libs/composer/vendor/ezyang/htmlpurifier/library/HTMLPurifier/AttrDef/CSS/Font.php
