Giving PWA icons transparent backgrounds

 I changed some of my icons to have transparent backgrounds. These were the icons mentioned in the 'manifest' files of my Progressive Web Apps (PWA).


I had given the icons white backgrounds to make them clearer as recommended by the PWA tutorial on Google's 'web.dev'. But these looked strange next to other icons on a Windows desktop.


I made all my web pages PWA's by adding a 'manifest' file and starting a 'do-nothing' service worker. Chrome warns that loading these service workers slows things down.

Dark mode using 'invert' does not work on Firefox

 Implementing 'dark mode' with 'invert' on the 'html' tag does not seem to work on the old Firefox used in my local libraries. This version of Firefox does not invert the background. This Firefox just inverts the elements you add. The Firefox developers feel they are following the specification. Using 'invert' when there is an 'overlay' scrollbar on Chrome sometimes makes the scrollbar disappear. I am using the last version of Chrome on Windows7. I understand 'overlay' scrollbars have been removed from the latest versions of Chrome. Of course, a dark scrollbar on a black background does not make sense. So I would need to use 'color-scheme' to change the color of the scrollbar. But 'invert' does not work well with 'color-scheme'. I could not set the colour of this 'overlay' scrollbar with properties like '-webkit-scrollbar-thumb'.  So I am going to have to implement 'dark mode' by setting the...
