jQuery Screen Resolution Height Adjustment

Question

In order to better balance out a page I am working on I would like to find a way to increase the top margin of a DIV depending on the screen resolution. What is my best way to set these dimensions with jQuery or Javascript?

Thanks in advance. Brad

Answer 1

Check out the jQuery dimensions plugin

Answer 2

To get screen resolution in JS use screen object

screen.height;
screen.width;

Based on that values you can calculate your margin to whatever suits you.

Answer 3

Here is an example on how to center an object vertically with jQuery:

var div= $('#div_SomeDivYouWantToAdjust');
div.css("top", ($(window).height() - div.height())/2  + 'px');

But you could easily change that to whatever your needs are.

Answer 4

Another example for vertically and horizontally centered div or any object(s):

 var obj = $("#divID");
 var halfsc = $(window).height()/2;
 var halfh = $(obj).height() / 2; 

 var halfscrn = screen.width/2;
 var halfobj =$(obj).width() / 2; 

 var goRight =  halfscrn - halfobj ;
 var goBottom = halfsc - halfh;

 $(obj).css({marginLeft: goRight }).css({marginTop: goBottom });
