Like my other post this is another website template. Although this one is a lot simpler, this template uses water.css to make a simple black or white themed page this includes the same blocks as my other post except this one doesn't have a url nav at the top to change the theme from light to dark or dark to light just switch the tag on line 7 to:
link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/kognise/[email protected]/dist/dark.min.css"> for dark and:
link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/kognise/[email protected]/dist/light.min.css"> for light (note: you may need to change the nav-bars color to match your template) or you can set it to any other water.css theme.
EDIT: thanks @Kognise for working on water.css
