uniapp background image does not display

In uniapp, we can use CSS styles to set background images. But sometimes, when we set the background image in the application, we find that the image cannot be displayed normally. This may be due to the following reasons:

1. Incorrect image path setting

When setting the background image, we need to ensure that the image path is set correctly. If the path is set incorrectly, the image will naturally not be displayed correctly. Therefore, we need to check whether the path is set correctly.

2. Image size setting error

When setting the background image, we need to ensure that the image size is appropriate. If the image display exceeds the set size range, the image will not be displayed correctly. Therefore, we need to check if the image size is set correctly.

3. Static resources are not packaged

In uniapp, we need to store static resources in the src folder, such as: pictures, audio, videos wait. If we add new static resources but do not package them, these resources will not be displayed correctly in the application. Therefore, we need to repackage static resources.

4. Conflict between background color and background image settings

When setting the background image, we need to ensure that the correct style priority is obtained. If the style settings conflict, the background image will not display correctly. Therefore, we need to check whether the background color and background image settings conflict.

Solution:

1. Check the image path

Make sure the image path is correct. In uniapp, we need to use relative paths to set the image path. For example, if we need to put the image into the static folder in the project, the image path should be /static/images/background.jpg.

2. Check the image size setting

Make sure the image size is set correctly. If the image size exceeds the set size, the image cannot be displayed normally. Therefore, we need to check whether the image size set is correct.

3. Package static resources

Repackage static resources. In uniapp, we need to put the static files into the src folder and rebuild the application through the re-build command. When packaging an application, ensure that the packaged static resource paths are correct.

4. Get the correct style priority

Make sure you get the correct style priority. When setting the background image, we need to check whether the background color and background image settings conflict. If the settings conflict, we need to reset the style to ensure the correct style priority.

Summary:

In uniapp, we can use CSS styles to set background images. But sometimes, the image cannot be displayed normally. This may be caused by the wrong path setting, wrong image size setting, unpackaged static resources, or conflicts between background color and background image settings. To solve these problems, we need to adopt corresponding solutions. Only by ensuring that the image path is correct, the image size is set correctly, the static resources are packaged and the style priority is correctly obtained, can we make the background image display normally.
