[fpc-pascal] New FCL-CSS package in the GitLab repo
@Michael Van Canneyt
I didn't test but I hope this package can parse this _minified_ CSS
file? Attached on the forum

It has many tricks. E.g. @media blocks (@media supports nested blocks,
not only 1 level), e.g. {} block for N classes, e.g. weird class names.

Minified or not is normally not relevant for parsing.

Nested blocks are supported.
But weird class names:
extractcssclasses brackets.min.css -o out
Exception at 004C107B: ECSSParser:
Error: line 9, pos 18: Unexpected token: Got ctkIDENTIFIER (as UTF8String:
"zoom"), expected: ctkCOLON .
"*zoom", really ? That's not even valid CSS syntax.
I checked 2 EBNF grammars: neither will allow this.
I checked the W3 spec: Confirms this is simply not valid syntax.
Browsers are simply very forgiving for all the junk found in CSS files:
The CSS syntax is so sloppy, almost impossible to cover all cases.
That's why there are a lot of test files.
But patches to make the implementation more forgiving are welcome.
I suppose things like *zoom can be easily supported.
Do you have the unminified file ? So I can see how to interpret the '*zoom':
treat as '* zoom' or as identifier '*zoom'

But "*.nnn" is valid one. https://css-tricks.com/almanac/selectors/u/universal/ So if the "*" has meaning in one context, it is not the id-char, it is special construct. Do you have the unminified file ? nope. treat as '* zoom' or as identifier '*zoom' as "* zoom".

The problem is that spaces are meaningful. so * zoom and *zoom are not the same. Do you have the unminified file ? nope. treat as '* zoom' or as identifier '*zoom' as "* zoom". Thanks, I wil check...

I did some more checking. As a selector * can be used in some cases:
the universal selector. but it can not be used as a property name.
in your file:
.clearfix{*zoom:1}
*zoom is a property name, not a selector. and properties must be
identifiers. According to the spec, identifiers do not start with a *.
I will add some options to interpret "*zoom" as a property name, but they will
off by default.
Michael.
