Overview

Instance Attribute Summary

• - (Array<Sequence>) members readonly The comma-separated selector sequences represented by this class.

Instance Method Summary

• - (CommaSequence) do_extend(extends) Non-destrucively extends this selector with the extensions specified in a hash (which should come from Sass::Tree::Visitors::Cssize).
• - (CommaSequence) initialize(seqs) constructor A new instance of CommaSequence.
• - (String) inspect Returns a string representation of the sequence.
• - (CommaSequence) resolve_parent_refs(super_cseq) Resolves the Parent selectors within this selector by replacing them with the given parent selector, handling commas appropriately.
• - to_a
