fn parse_property_value(iter: &mut Peekable<Chars<'_>>) -> (String, bool)Expand description
Try to get the value of a CSS property (the #fff in color: #fff). It’ll stop when it
encounters a { or a ; character.
It returns the value string and a boolean set to true if the value is ended with a } because
it means that the parent block is done and that we should notify the parent caller.
