* Sizes Parser
*
* By Alex Bell | MIT License
*
* Non - strict but accurate and lightweight JS Parser for the string value < img sizes = "here" >
*
* Reference algorithm at :
* https : //html.spec.whatwg.org/multipage/embedded-content.html#parse-a-sizes-attribute
*
* Most comments are copied in directly from the spec
* ( except for comments in parens ) .
*
* Grammar is :
* < source - size - list > = < source - size > # [ , < source - size - value > ] ? | < source - size - value >
* < source - size > = < media - condition > < source - size - value >
* < source - size - value > = < length >
* http : //www.w3.org/html/wg/drafts/html/master/embedded-content.html#attr-img-sizes
*
* E . g . "(max-width: 30em) 100vw, (max-width: 50em) 70vw, 100vw"
* or "(min-width: 30em), calc(30vw - 15px)" or just "30vw"
*
* Returns the first valid < css - length > with a media condition that evaluates to true ,
* or "100vw" if all valid media conditions evaluate to false .
*
