css images cannot be displayed

CSS (Cascading Style Sheet) is a language used for web page style design. It can control various properties such as web page color, font, layout, size, etc. At the same time, CSS can also control the display of images in web pages. However, in actual use, sometimes you encounter situations where pictures cannot be displayed normally. This article will introduce some of the common situations and their solutions.

1. Picture file path error

In HTML, the img tag is used to insert pictures. When inserting an image using the img tag, you need to specify the path of the image. If the path is wrong, the image will not display properly. This problem is often easily overlooked because the path to the image file appears to be correct, but common spelling errors such as parentheses, slashes, or backslashes can cause the image to fail to load. Therefore, when encountering this kind of problem, you need to carefully check and make modifications to ensure that the file path is correct.

2. The image file does not exist

Sometimes, when we add images to a new website, we may upload the image files to the wrong folder or website server. The resulting pathname is incorrect and the browser cannot find the file when trying to get it from this directory. This situation is easily overlooked, but it is also necessary to carefully check whether the image file exists, find out the cause, and solve it in time.

3. The image file format is incorrect

When the browser tries to load an image, it must not only find it, but also be able to decode and render it. If the image is not in the correct format, the browser will not be able to decode the file correctly and will display a blank space. Therefore, we need to ensure the correct image format such as jpg, png, gif, etc. At the same time, if the image file is too large, the browser may not be able to load the image correctly. Therefore, we also need to pay attention to the size and dimensions of the image file to ensure that it can be displayed properly in the browser.

4. Browser caching problem

The browser’s caching function is to improve the loading speed of web pages. But sometimes, the cache files in the browser may be corrupted, causing the browser to fail to load images correctly. Therefore, we recommend clearing your browser cache and reloading the web page or image file in your browser to ensure that the image displays properly.

5. Other problems

In addition to the above problems, there may be other problems, such as network instability, server failure, etc. For these problems, we need to contact the website administrator in time and check the server settings and network connection to ensure that the pictures are displayed normally.

In short, there may be many reasons for CSS image display problems, but we only need to carefully check the file path, file format, cache, network and server and other possible problematic aspects, and solve the problem in time. In this way, we can ensure that the images in the web page can be displayed normally.
