The report has it that the latest update of Opera for Android browser now has the ability to give any webpage a dark mode
Smartphone manufacturers and app developers are already introducing us to the dark mode feature. In a situation where the feature is not familiar, dark mode basically gives the app or smartphone a dark appearance so it is easier to use in low-light situations.
The app has also given us the benefits of a good battery life, especially with devices that use OLED displays.
If a website is not designed for dark mode, Opera will turn the background dark. At first, it takes the white background, and then turn it to dark through some CSS (Cascading Style Sheets) changes.
Cascading Style Sheets is a style sheet language used for describing the presentation of a document written in a markup language
If you do not want to end up using glasses like me, it would be better to try out this useful feature.
