niso

CSS

Generated from idl/cssom.webidl when the site was built at 7aa23e2.

CSS is a namespace in idl/cssom.webidl, exposed in Window. What it does is on MDN; this page says what niso has of it.

CSSOM’s escape() and CSS Conditional’s supports(). The standard’s two supports() overloads are one operation here, told apart by whether value is given.

escape()

Section titled “escape()”
operation 
DOMString escape(DOMString ident);
int32_t niso_css_escape(niso_dom* dom, const char* ident, size_t ident_len, niso_str* out);

supports()

Section titled “supports()”
operation 
boolean supports(DOMString conditionTextOrProperty, optional DOMString value);
int32_t niso_css_supports(niso_dom* dom, const char* condition_text_or_property, size_t condition_text_or_property_len, const char* value, size_t value_len, bool* out);

parseTransformList()

Section titled “parseTransformList()”
operation not in JS 
[NisoInternal] Float64Array parseTransformList(DOMString text);
int32_t niso_css_parse_transform_list(niso_dom* dom, const char* text, size_t text_len, niso_bytes* out);

The Geometry Interfaces’ parsing of a DOMMatrix’s string: the matrix of a <transform-list> of absolute lengths, m11 to m44, then 1 when every function is 2D or else 0, as native-endian doubles; a SyntaxError when it does not parse.
