Simple countdown widget

countdown.js

// Variables used by Scriptable.
// These must be at the very top of the file. Do not edit.
// icon-color: blue; icon-glyph: calendar-alt;

// Created by u/flasozzi
// Background image code by u/ben5292001

// READ THE INSTRUCTIONS BELOW
// You need to both edit the code and add parameters in order to personalise the widget.

// To add parameters, add the widget to your home, long press it and tap 'edit widget'
// Your parameter must have the following format: image.png|padding-top|text-color|countdown-end-date|countdown-title
// The image should be placed in the iCloud Scriptable folder (case-sensitive).
// The padding-top spacing parameter moves the text down by a set amount.
// The text color parameter should be a hex value.
// For example, to use the image bkg_fall.PNG with a padding of 20, a text color of red with a countdown to your holidays on Dec 16 2020
// the parameter should be typed as: bkg_fall.png|20|#ff0000|December 16 2020|holidays
// All parameters are required and separated with "|"
// Parameters allow different settings for multiple widget instances.
