Web Design HTML CSS

BQ, yes i was meaning JavaScript, animation.. btw, I much prefer CSS for what I can do it. I'm still learning, so that's why I'm here, a sort of hippy when is about merging and changing titles... so, no excellent or even just enough good.

Fair enough :-)

A good knowledge of JS is essential to be a decent FED, but how much and what kind of JS you'd use really does depend on what you're building. With websites you aim to do the heavy data lifting on the back-end, use as little JS as possible, and if native HTML or CSS then you leverage that. But then if you're building a full app then the whole thing might be JS driven, and you'll be using JS to write HTML templates and construct a full MVC stack and do all sorts of heavy lifting right there on the client, and instead of small size your biggest concern will be memory management and execution speed. Like a 'proper' programmer :-)
