nightlife v1.3.2
nightlife
nightlife detects users location and calculates sunrise and sunset time at their location, to apply a different style at night time.
If user location can not be retrieved, it is assumed that the night goes from 6pm to 6am, local time.
Install
<!-- inside your <head> -->
<script defer src="http://unpkg.com/nightlife/dist/nightlife.js"></script>Night mode CSS
If you want a default basic night theme, you can use this one: it inverts the lightness of all colors except for images and videos.
<link rel="stylesheet" href="http://unpkg.com/nightlife/dist/nightlife.css" />If you want your own styles at night time, use this media query:
@media (prefers-color-scheme: dark) {
/* these styles will apply at night time */
/* or if user explicitely asks for a dark color scheme */
body {
background-color: black;
}
}This media query is currently not supported on most browsers, so you will also have to use this : css-prefers-color-scheme
