Dark mode?
 

Would it be possible to get a dark mode/theme for the mobile site?

Ooooooo.... +1

That would be something the site owners, Internet Brands, would have to address. They determine the look of all their web sites.

Any way to bring it to their attention?

When they redesigned this site's appearance they gave zero attention to any input from us or our ideas about it, so...

Do you have night mode on your phone? I have a Note 9 and the night mode option works great when viewing this site.

Yah, I have always On Night Mode but the forums are still white on my phone.

If you are using a theme on your phone, try turning it off and see if it makes a difference.

Nope, still white.
