white space after the footer, only in firefox and ie

css, firefox, html, internet-explorer

Solution

In `stylesheetmain.css`, you have this rule:

.fellows #insightpictures .buttons {
    margin: 635px auto;
}

Change `margin: 635px auto;` to `margin: 635px auto 0;` to remove the bottom margin.

Problem

There seems to be random white space after the footer at the bottom of the site, but it only shows up in IE and Firefox. The site pulls up fine in Safari and Chrome. When I try to use inspect element, the white space doesn't seem to fall under any tags. It doesn't seem tied to any footer tags either as removing them didn't change anything. The site link is: http://www.insightdatascience.com. I've looked at a ton of answers, but none seem to work for my site specifically. Thanks!
