Question

What is the correct jquery code for making all div elements 100 pixels high?

Answer 1

$("div").height(100) is the correct jquery code for making all div elements 100 pixels high.  

So, the $ sign is a shortcut for jQuery. The $("div") represents selection of all div elements and to make the 100 pixels high add height(100) with jquery code. jQuery.ajax() method is used to perform an asynchronous HTTP request.
