How to animate text using JavaScript

I want to implement animated te开发者_运维百科xt i.e. moving the text from bottom (half of the page) to the top like marquee. I don't get any good code. Does any one know how this is implemented in JavaScript or jQuery or DHTML?

Thanks in advance

use jquery

  $('#mydiv').animate({
    top: 0
  }, 5000, function() {
    // Animation complete.
  });

Check the demo here

Same code as the answer below but, it sets the TEXT location to be at half the page's height, and then animates it to top:

//Calculate where is HALF of the page (half the window height)
var start_pos = screen.height/2;

//Set starting TOP location
$(".text").css("top", start_pos+"px");    

//Animate to the END location, which is 0px
$(".text").animate({ top:0+"px" }, 5000, function() { alert("Animation Complete"); });
