Positioning a DIV Centrally on the Web Page with jQuery
The centering of a DIV element on the screen is a common requirement in web development. jQuery offers a handy solution to achieve this.
Solution:
To center a DIV using jQuery, you can leverage the following function:
jQuery.fn.center = function () { this.css("position", "absolute"); this.css("top", Math.max(0, (($(window).height() - $(this).outerHeight()) / 2) + $(window).scrollTop()) + "px"); this.css("left", Math.max(0, (($(window).width() - $(this).outerWidth()) / 2) + $(window).scrollLeft()) + "px"); return this; }
This function modifies the DIV's position by calculating the center coordinates based on the screen size and the DIV's dimensions.
Usage:
Once the function is added to jQuery, you can simply call it on the target DIV using the following syntax:
$(element).center();
This will center the DIV on the screen.
Demo:
To demonstrate this function, you can refer to the following Fiddle, which includes an additional parameter to control the centering precision:
