Hey with just a simple line of code you can show and hide a div...
Before Jquery we write our code something like :
For hiding a div : document.getElementById(id).style.display = 'none';
For Showing a div: document.getElementById(id).style.display = 'block';
and now with the cool feature of JQuery :
For hiding a div : $("#divResult").hide();
For Showing a div: $("#divResult").show();
And also we can play around with this
like
$("#divResult").show(2000);
It will slowly display the div in 2 seconds.....
And for hiding
$("#divResult").hide("slow");
Its hides your div slowly..
Cheers...
