some good online resources/link for html css javascript

hi guys,
I'm new to this forum. i have just jumped in the world of client side technologies comprising html,css,javascript,jquery etc. i would like to know some good online links/resources from where i can learn them.

http://www.w3schools.com/ is a good place to start.

or not

Oh, drag. I used to always go there when I was an HTML beginner. Sometimes I still do. I don't remember getting too much bad advice from them. Many of those comments seemed a bit picayune though, and are they even all correct? They say you can't put an <input> tag inside a <form> tag until HTML5. I don't have an old browser to confirm that, but if it's true, where could you put it?

Even if they're weak on content, they're great at SEO. I get them as the top five Google hits for "CSS reference" (not in the top five -- the top five) and the top three for "HTML reference". What's a better place to go?

I don't know of any. I use it occasionally, but just be aware that not everything they say is gospel.
