We have been looking at changing the body background on a theme based on hour, day, month, or season, in this example we will find out how to change the background in the evening.
We are using a Twenty Ten child theme to do this, so what do we need, we are using two horizontal repeat .png images 1087 wide * 1120 high, one for day and one for the night, if we whanted a different set of images, for any of the other methods we would change the quantities, names and code values to suit.
