jQuery Tutorial plus Question:

In jQuery, there are two way to change the width of an element.
One way is using .css('width') and other way is using .width().

For example:
$('#mydiv').css('width','300px');
$('#mydiv').width(100);

★ The difference in .css('width') and .width() is the data type of value we specify or return from the both functions.
★ In .css('width') we have to add "px" in the width value while in .width() we don't have to add.
★ When you want to get the width of "mydiv" element then .css('width') will return '300px' while .width() will return only integer value 300.
