Google Search, the main thing Google was known for before it became an all-encompassing tech albatross, will let all users switch to a dark theme in the coming weeks, per a post on Google’s support website. The classic white search webpage that’s been our door to the rest of the internet for a couple of decades can now be dark grey if you want it to be. This is desktop only for the moment.
This can be achieved by going to the settings menu (bottom right corner on the Google homepage, top right corner on any search results page), clicking “Search settings,” and then clicking “Appearance” on the left sidebar from there. I’d demonstrate this with a screenshot, but Google is rolling the feature out gradually and I don’t have it yet. Seems unfair, but oh well.
