The CSSVariablesRule interface represents a @variables rule within a CSS
style sheet. The @variables rule is used to specify variables.
cssutils uses a :class:`~cssutils.css.CSSVariablesDeclaration` to
represent the variables.
Format::
variables
VARIABLES_SYM S* medium [ COMMA S* medium ]* LBRACE S*
variableset* '}' S*
;
for variableset see :class:`cssutils.css.CSSVariablesDeclaration`
**Media are not implemented. Reason is that cssutils is using CSS
variables in a kind of preprocessing and therefor no media information
is available at this stage. For now do not use media!**
Example::
@variables {
CorporateLogoBGColor: #fe8d12;
}
div.logoContainer {
background-color: var(CorporateLogoBGColor);
}
