38// CSSGridAutoRepeatValue stores the track sizes and line numbers when the auto-repeat
39// syntax is used
40//
41// Right now the auto-repeat syntax is as follows:
42// <auto-repeat> = repeat( [ auto-fill | auto-fit ], <line-names>? <fixed-size> <line-names>? )
43//
44// meaning that only one fixed size track is allowed. It could be argued that a different
45// class storing two CSSGridLineNamesValue and one CSSValue (for the track size) fits
46// better but the CSSWG has left the door open to allow more than one track in the
47// future. That's why we're using a list, it's prepared for future changes and it also
48// allows us to keep the parsing algorithm almost intact.
