Onload Fancy box using Jquery, yes it may harmful to web page. it is like a popup box. popup box is one of the most irritating thing in web designing and web development, but most of them need this script for their own, personal and e-commerce site.
It is very simple thing, it is similar like a alert script in java script. let see the coding for the Onload Fancy box using Jquery. here in the script the box will be open after 5 minutes of the page load.
Just call the image and class="close" for close the image box. as the above code.
Jquery min file is important one, and the setTimeout is to open the image or box within a sec. here i declare 5000, which means 5 sec. just used fadeIn and fadeOut concept for this.
i just fix the image in center of my browser, change it as your wish. position:fixed; is to fix the image in the same place while scrolling. i hope this may useful and interesting.
