A JavaScript API which makes it easy to perform various standard JavaScript actions
JQuery takes care of cross browser compatibility issues, so you can focus on getting your page to work as intended.
What can you do with Jquery?◦ Select HTML elements in various ways, easing access to the elements to be enhanced.◦ Style the HTML elements dynamically, by manipulating their CSS properties or classes.◦ Manipulate the DOM (Document Object Model) of your page, (copy, move, modify etc.)◦ Animate the DOM elements, e.g. fading in / out, sliding, change color, change size etc.◦ Respond to events like mouse-over, mouse-out, change etc.◦ AJAX enable your web pages using JQuery's smart AJAX features.◦ Use the many JQuery plugins (incl. JQuery UI), which contains all kinds of smart widgets.◦ Create advanced web application user interfaces, which resemble desktop user
interfaces. JQuery works naturally with the HTML elements in the browser, so it doesn't
matter if they are HTML 4 or HTML 5 elements. As long as your browser supports it, so does JQuery. You can find JQuery at JQuery.com.
When you use JQuery, you typically follow these steps of action:◦ Wait for the page to be ready.◦ Select some HTML elements to modify.◦ Traverse the selected HTML elements.◦ Modify the HTML element attributes, CSS styles
etc.◦ Add listener functions, e.g. click() or wait for a
JQuery effect to finish etc.

The jQuery syntax is made for selecting HTML elements and performing some action on the element(s) at http://www.w3schools.com/jquery/jquery_syntax.asp
Basic syntax is: $(selector).action()
