I found a CodePen the other day that showed a method for a rain effect on a web page. I like it a lot, so I’ve modified it to work without a pre-processor, and included instructions for how to add it to a Midnight page (or any other, for that matter). There are, of course, plenty of other ways to play with it. I’ve tried to make it as simple as possible to customize the basics, but going beyond that will require at least some knowledge of JavaScript and/or CSS.
Let me know if you have any questions, and I’ll do my best to answer them.
sorry, unrelated—but is your name an HoL reference?
Rain is definitely a top 3 weather phenomenon. Also, thanks for reminding me that I have my own room at the Midnight!
