The best, easiest way to set up a dark theme for WordPress admin is to install the Dark Reader add on for the Firefox Browser. The add on is also available for Chrome; however, if you’re interested in getting off of Google products, here’s a guide to the best Gmail alternative.
Back to Dark Reader though. I absolutely love this add on. Just take a look at what it does to the WordPress admin with the simple click of a button:
And because, you’ll want to easily be able to see what your site visitors are seeing, Dark Reader has an easy toggle between dark mode and normal viewing: Alt + SHIFT + A. This means you can easily jump back and forth while having a nice dark admin theme that reduces eye strain.
And I find that I’m using Dark Reader across the board. I just leave it on all the time to reduce eye strain when using the web.
Want to go completely dark and save your eyes? I recommend it.
Great for Writers
Where this is really useful is for writing. If you write a lot of articles in WordPress, you know about the eye strain involved from the bleach-white screen. It gets painful over time.
With an admin dark theme, you can really lower the stress caused by staring at the screen. When using a dark theme, there’s a lot less energy/light coming out of the screen. Another benefit is that a dark theme will save battery power if you’re on a laptop.
