Dark Mode by Traslatability
Give your site a dark mode your readers can switch on — one that reads properly on every page, without you restyling anything.
Everything you need to run a dark site well
It reads your theme
Every stylesheet on the page is read and re-coloured, element by element, so a dark page still looks like your site rather than like an inverted photograph of it. That is the difference between a dark mode a reader keeps on and one they switch off after a paragraph.
Nothing loads until it is wanted
A visitor who never turns dark mode on downloads about seven kilobytes. The engine — the part that does the real work — is fetched the moment somebody chooses dark, and never before.
No white flash
A few hundred bytes go out ahead of the page and set the colours before the first paint. A reader who chose dark last time never sees a white page appear and then correct itself, which is the single thing that makes a dark mode feel bolted on.
Six palettes
Ink, Slate, True black, Warm, Midnight and Forest — every one of them checked for contrast before it shipped, so picking one and changing nothing gives you a page people can read. Change any of the four colours and the change is yours to keep.
A switch you can put anywhere
Four styles, five corners, your own wording and colours. Or hide the floating button and place it yourself: as a navigation menu item, a block, a shortcode, or a link in your own template. All of them ask one screen for their wording, so none of them can drift, and every one says what it does out loud for a screen reader.
Or a keyboard shortcut, or a link
Alt and a letter, never while somebody is typing. And ?dark=1 on any address opens that page dark — read before the first paint, so a link you send in the evening does not flash white on the way there.
