Frame

The css generation state at one point of the compilation: which selectors are being emitted, inside which at-rules, and at which @order priority.

class MMO\client\scs\Frame

Namespace: MMO\client\scs

A frame creates its [`CssRule`](https://mmoframework.fr/documentation/mmo.client/php/scs/CssRule.md#cssrule) lazily, so a rule that ends up with no declaration of its own (because everything it contains is nested or responsive) never reaches the output.

Index

	emitter
	location	where the rule being emitted was written, for the source map

	declare($property, $value, $location)	Add a declaration to this frame's rule, creating it on first use.
	selector()
	__construct($emitter, $selectors, $wrappers, $order, $location)
