After going Dark for a couple weeks, got bug up my ??? to make some minor css tweaks.

How hard can that be? ... but where is devtools html and css?

see using devtools to inspect its own elements

• Enable DevTools experiments at chrome:https://flags/#enable-devtools-experiments
• relaunch Chrome and open DevTools
• open Settings > Experiments and check Allow UI themes experiment
• open devtools > setting > Experiments and check Allow custom UI themes

• download repository and unzip "zero II" folder
• open chrome:https://extensions
• Zero Dark Matrix must be removed -- zero II uses same extension ID
• click "Load unpacked extension..." and select extracted "zero II" folder
• close and re-open any open "Developer Tools" windows
