- * This lexer splits an input by whitespace, brackets, and semicolons.
- * Brackets and semicolons are included in the lexed output, whitespace is not.
- * <br>
- * CSS, thankfully, is far more rigid and less-forgiving of errors than HTMl.
- * It also has multiple layers of fallback for errors: ranging from: "ignore this
- * property", to "ignore this rule", to "this isn't fucking CSS" and ignore it all.
- * <br>
- * Still, even though we don't have to deal with garbage like escaped quotes (future edit: whoops, yes we do) and
- * what not, we'll still implement our lexer with a for loop instead of split() for future optimizations.
