valid order for attributes of input type tag

I know it's very basic question and hope not so important, but i want to know the answer, please don't suggest only refer links. we all daily face `<input>` type tag and their attributes (`type, class, id, value, name, size, maxlength, tabindex etc..`), I just want to know - is there any specific order required for attributes in `<input>` tag or can we use any order? - if there an order then what is it?
