I like many code using Dark Themes. For Sublime, Atom, and other popular editors dark modes are typically the default and also the mostly popular in regards to custom themes for such editors. Inspectors in browsers oddly have always been light themed. A while back Chrome allowed users to add a custom stylesheet to style the inspector to be dark and several themes existed to do such. While I believe Safari supports that, at the time at least it didn't seem to support it as well and there was no way porting the dark themes to Safari. Also even in Chrome, with all the updates, third party git hub developers didnt usually update the themes and thus the inspectors ended up looking odd. Chrome Inspector recently now supports a native dark mode via their preferences which is wonderful, and makes going from a standard editor such as Atom, to Chrome seamless. Would love to see that feature added to Safari.
We have gotten a few requests for this. Thanks for writing in. *** This bug has been marked as a duplicate of bug 169511 ***
