Bookmarklet: Print to pdf ali express order page with all the info shown and filename set to "order id - price"
// The way I used it is to open all my orders one by one from the order page
// and then start clicking on this bookmarklet starting from the first order tab
// the bookmarklet changes the title and shows the finance tab
// then launches the print dialog and closes the tab.

This adds an overlay mask around any given element!
var surroundWithOverlay = function(target) {
var $t = $(target),
offsets = $t.offset(),
height = $t.height(),
width = $t.width(),
clearUs = function() { $('.overlayDivs').remove(); };

A small script for hackathon.io - http://www.hackathon.io/events that makes tiles look better.
(function() {
var all = $('.block-grid.five-up > li').toArray();
all.slice(5).forEach(function(current, index) {
index += 5;
var el = $(current),
offset = el.offset(),
above = $(all[index-5]);
el.css({
position: 'relative',
