How Can I Center a DIV Element on a Web Page Using jQuery?

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;
}
Copy after login

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();
Copy after login

This will center the DIV on the screen.

Demo:
