v.3.0.0

The whole library has been simplified by reducing it's code and changing method to add new animated gradients.
To initialize the library you have to assign it to a variable:

var gf = Gradientify()

And then just use its methods to make new animated backgrounds:

gf.gradientifize(document.body, [
  'linear-gradient(60deg, rgb(255, 91, 91), rgb(0, 0, 255))',
  'linear-gradient(10deg, rgb(180, 132, 203), rgb(255, 0, 155))',
  'radial-gradient(at center center, rgb(75, 35, 148), rgb(0, 71, 57))',
  'linear-gradient(130deg, rgb(235, 23, 223), rgb(25, 89, 135), rgb(15, 189, 176))'
], 2600)
