Is there any code formatter for HTML, CSS, JavaScript to format code quickly in SO editor friendly format?

I want to format code in good manner and without having horizontal scroll bar for source in question.

Why not format your code properly before you insert it into your question? You can format code much faster in your native editor than in anything else.

I use vim for everything, so I write my code in a vim window and then paste it. Often I start answering a question in the browser and then need to write some code, so I use the Firefox plugin "It's All Text!" to invoke a vim instance, edit my code and format it properly, and it is automatically inserted into the browser text box.

If you limit the width in your native editor to 80 characters (and use a tab-width of 4, if you're using tabs, which will show as at most 4 spaces in Markdown), it will probably render without any horizontal scrollbar in most browsers:

         1         2         3         4         5         6         7         8

@Jitendra , you'll need to limit the line width in your Dreamweaver editor. – Arjan Apr 24 '10 at 16:59
