I am using Mixitup JQuery for a portfolio page that sorts my content between a few different filters. When I click on an item now, the Jquery works and the content shuffles, but the buttons jump up about 50px for a second, before going back to where they have been positioned.
If you double click on the same link, "web" or "contact", you can replicate this. – Marc Jenkinson 43 mins ago

$(function(){
$('#content-column').mixItUp();
});
