I know neither of those versions. It's been a few years since I learned html/css.
i'm guessing most tutorials will focus on the new stuff in html5 (media and whatnot) and css3. so just learn the basics of the previous versions. it won't take long. there's no reason to memorize every tag. just learn how to use tables, divz, header vs body, line breaks, image, paragraph, common encodings, and whatnot. Should only take a few minutes.
as for css, again, just learn the basics. make sure you understand the difference between where to define css (inline, header, separate file). id, class, inheritance. after that, a few minutes of playing around with specific things is sufficient. how to change colours, change alignment, styling text, borders/padding, etc.
these are things you just need to learn the basics for, understand how to use them, then look up specific tags when you need them. based on your goals in the other topic, there's no reason to study so much. if your studies are so long that you want to skip html to learn html5 then go back to it, then you're doing it wrong.in all likelihood, you'll be using software to aid making websites for you. you'll use free skins or something like dreamweaver. the only people who really need to study css in great detail are people who are very big into web design, which you are not.
