I'm currently taking a short course on HTML5/CSS and WordPress, this change wasn't exactly deliberate, it was a side-effect of something else I was doing.
I tend to use the Firefox 'dark mode' add-on a lot lately, it reverses the colors so the text is white on dark. I find it a lot easier to read, and I tend to increase the font size for readability, too, though that messes up a lot of web pages and apps. Hopefully my eye doctor appointment, which was originally scheduled for March but has been postponed twice due to covid19, will take place in June and I can get new glasses.
I will need cataract surgery in the next few years, but probably not this year.
You may see some flip-flopping between the old and new layouts, I'm still trying to figure out exactly what got changed and why.
