Help me center addthis on html page

I have setup addthis to my index.html

I have used html center tag, and it just will not center on the page.

any help would be appreciated.

You can see it here.

First validate html coding a lot of errors on it....

 

For what is there, I am not concerned with errors...

Would just like to center addthis...

 

Try to add <center> tag after your body tag like below (and also remember to close it at the end of body)

 

that would normally center the entire page from there, but that did not work.
center tag does not seem to affect addthis, but I did try it...

 

Maybe this will help. It does not help me because I do not understand code, i did
attempt to place it, but it was a bad turn out, not sure exactly how it is to be implemented.

To center an AddThis toolbox you have to give the div with the class addthis_toolbox a width and define the horizontal margins so that it pushes the div to the center. Here's an example:

div.addthis_toolbox {
width:33%;
margin-left: 33%;
margin-right: 33%;
}
