Shining the Light on HTML Email Dark Modes
summary
Maintains canIemail.com and shows five practical fixes: always test (use parser.io and Firefox devtools), prefer transparent images or add invisible outlines for dark backgrounds, and add the Apple Mail meta/color-scheme so CSS dark rules and picture switching work. For Outlook.com use the data-ogsb/data-ogsc attributes plus class-name exclusion to emulate light/dark, and for Gmail apply a linear-gradient background plus difference and screen blend modes to keep button colors intact. Notes Outlook for Windows moving to Edge WebView.
