Here are a few tips Moath Alqutoob,

All selectors in jQuery start with the dollar sign and parentheses: $().

In jQuery, the $ sign it's just an alias to jQuery(), then an alias to a function.

Here are some samples:

Basic syntax is: $(selector).action()

A dollar sign to define jQuery A (selector) to "query (or find)" HTML elements A jQuery action() to be performed on the element(s)

My advice.... get to know Javascript first. Then once you get to know the basics then you can jump into the dollar sign $ (jQuery). And believe me, you will love all the "shortcuts" techniques of jQuery.

Have fun!

How did the $ sign get used? In JavaScript you can also use dollar signs in variables.

If you're using jQuery, the $ can be used as an alias for jQuery. I suggest checking out the documentation here: http://api.jquery.com/jQuery.noConflict/
