I was reading a novel on the web and changed it to night mode. Why did I change it back? You can change the display mode of the webpage to normal mode through the settings of the browser. The specific steps were as follows: 1 Open your browser and click on the "browser icon". 2. Choose the " Setting " option from the menu that popped up. 3 Find the Advanced tab in the settings window. 4. Under the Advanced tab, you can see many options about the browser settings, including the "display mode" option. 5 Touch the "display mode" option and select "normal". 6 Wait a few seconds. When the browser displays normal mode, you can try to change the display mode again and select "Night Mode". I hope this method can help you restore the night mode of the web page.
