Solutions to the problem that css cannot display images: 1. Check whether the css call is successful; 2. Check whether the div setting is wrong; 3. Check the background image calling path and modify it; 4. Set the width and height of the background element; 5. Set the element to have block attributes; 6. Check whether it is overwritten by the style of the CSS class with the same name and modify it.

The reason why the background image set by css is not displayed
1. The css is not called
It is necessary to check whether the css call is successful.
2. Wrong div settings can easily cause the background image to be too high to be displayed.
3. Wrong background image calling path
css background used to set the background, writing method It's .div{backgroud:url('1.jpg');}. Check whether your css is written correctly. The picture is not displayed. It may be because the picture is stored in the wrong location. If you don't know where the picture is placed. How should the folder be written? You can put the html file and the picture together and directly write backgroud:url('1.jpg');
4. The background element has no width and height.
When the element has no width and height, the background cannot be displayed. The background does not expand the element. Set background-size.
The div box has no content and needs to set width and height.
5. The element does not have block attributes.
The height and width set when the element does not have a block attribute are invalid. So the picture will not be displayed.
6. Overwritten by the style of the css class with the same name.
Assume that the background display image is set by the name .bg in the front, and the background display color is set by the name .bg later.
At this time, you need to open the console (press F12 key) to view the CSS style background property.

React's one-way data binding ensures that data flows from the parent component to the child component. 1) The data flows to a single, and the changes in the state of the parent component can be passed to the child component, but the child component cannot directly affect the state of the parent component. 2) This method improves the predictability of data flows and simplifies debugging and testing. 3) By using controlled components and context, user interaction and inter-component communication can be handled while maintaining a one-way data stream.

Use Context and useState to share states because they simplify state management in large React applications. 1) Reduce propdrilling, 2) The code is clearer, 3) It is easier to manage global state. However, pay attention to performance overhead and debugging complexity. The rational use of Context and optimization technology can improve the efficiency and maintainability of the application.

Using incorrect keys can cause performance issues and unexpected behavior in React applications. 1) The key is a unique identifier of the list item, helping React update the virtual DOM efficiently. 2) Using the same or non-unique key will cause list items to be reordered and component states to be lost. 3) Using stable and unique identifiers as keys can optimize performance and avoid full re-rendering. 4) Use tools such as ESLint to verify the correctness of the key. Proper use of keys ensures efficient and reliable React applications.
