How can I change a full webpage to negative? Say a want to add a toggle option for the visitor. This has something to do with white backgrounds which I want to turn black to make OLED screens happy. OLED consumes three times more power with whites compared to conventional TFT. But I want that NEGATIVE apply only to texts and background leaving the rest like pictures and videos untouched. This idea should be great for mobile phones with OLED screens.
thanks in advance
