1. When the user rotates the device, the device will send an event notification application to tell the application that the device is in landscape or portrait mode;
2. In most cases, the application will adjust its layout when the device is in landscape orientation;
3. The application can decide how to display the screen content based on this event so that more content can be displayed on a wider screen.
1. You can use some frameworks, such as Bootstrap, Foundation and Semantic UI, etc. These frameworks already include CSS classes that adapt to the screen;
2. All you need to do is apply these classes to your application so that it automatically adapts to the screen orientation;
3. You can use @media rules to define different CSS rules to display different styles in different screen directions.
1. When the device is in landscape mode, you can define a @media rule to set a wider layout;
2. And hide some elements so that all content can fit on the screen;
3. Of course, in some cases, you may need to use JavaScript to achieve horizontal and vertical screen rotation.
1. You can use JavaScript to listen to device rotation events and recalculate and adjust the layout according to the device orientation;
2. Using JavaScript to implement horizontal and vertical screen rotation may reduce performance and may cause application delays;
3. When using JavaScript, you need to use lightweight methods to achieve rotation as much as possible.
