Let’s look at the conclusion first
Open the settings after entering full screen or Floating Prompt, and you can adjust the commonly used appearance in real time. It is recommended to solve the problem of "comfortable reading" first, and then pursue the concealment of the picture: the font size should be identifiable at a glance, there should be sufficient contrast between the text and the background, and the speed should be close to the rhythm of daily reading.
Adjustable items
Font size ranges from 12 to 100, with a default of 30 (42 for iOS floating prompts). Additional line spacing defaults to 10; it adds space beyond the font’s natural line height.
Notice
Transparency is not always better when it comes to transparency. When the background image is complex, excessive transparency will cause the edges of the text to disappear. After the horizontal and vertical screens, indoor and outdoor lighting, or window size change, it is recommended to quickly try reading again.
