A brief discussion on 6 reasons why CSS loading fails
In page layout, we all advocate the separation of structure and style, but sometimes, the css style cannot be loaded successfully. Why is this? This article mainly talks about 6 reasons why CSS loading fails. Friends in need can refer to it. I hope it will be useful to you.
Many novices who have just come into contact with CSS sometimes encounter the problem of CSS loading failure. However, during testing, the style is not displayed on the web page, which means that CSS loading fails. This situation usually occurs because the css path is written incorrectly, or the loading of css is disabled in the browser. You can restart the browser to refresh. When calling css in a file, you usually add your path through a link. To implement, you can look at the code for details:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>index</title> <link rel='stylesheet' type='text/css' href='./css/index1.css'>//注意好文件名的书写就没问题了。
There are many reasons for css loading failure. This may be related to errors in your code, browser, path, encoding, etc. So analyze the specific situation in detail. The most common reasons for failure are as follows:
1. Network reasons
Insufficient IIS space, slow browser network speed, slow space speed and other network factors are caused One of the reasons for CSS loading failure is as follows: when we open the web page, the web page layout is complete, but no layout style is displayed.
2. Path error or code incompatibility
If the style set by CSS is not displayed when the web page is opened, it will only be displayed in its original state. Then it may be that our CSS file path is wrong or the CSS code is incompatible.
3.if causes failure
The third reason is that when we write CSS, we may use if statements to determine which browser calls which CSS file. Inadvertence caused confusion in the if call, resulting in the normal display on some browsers but not on some browsers. For this reason, the solution is to carefully check the if judgment settings that cause CSS loading failure.
4. Alternative CSS loading failure
Why is alternative CSS loading failure? This is because there is a problem with our own CSS code writing, and it is not set properly, resulting in different layout differences in different browsers. In CSS, we call it a css hack.
5. The browser causes
Check the error console of the Chrome browser to see if the css file is loaded. If it is sure to be loaded, check the class of the element. Whether the name is the same as the class name defined in CSS. It may be limited to IE browser, and an error will occur if you use Google Chrome. So try changing the browser and using it later, which may fix the problem.
6. Wrong encoding
If it is not the above problem, check whether the character set of your CSS file is consistent with the character set of the webpage that calls the CSS file. Consistent, it is the charset attribute. When you use a browser to view the effect, there is a "View - Encoding" on the menu bar of the IE browser. Check the encoding to see if it is UTF-8 or GBK and see if it is the same encoding. It may be caused by inconsistent coding.
The above are the six most common reasons for CSS loading failure. After we understand these reasons, if we encounter similar problems in actual operations, we can check them one by one and prescribe the right medicine to solve the problem.

Describe different CSS units and when to use them
Jul 27, 2025 am 04:24 AM
In web development, the choice of CSS units depends on design requirements and responsive performance. 1. Pixels (px) are used to fix sizes such as borders and icons, but are not conducive to responsive design; 2. Percentage (%) is adjusted according to the parent container, suitable for streaming layout but attention to context dependence; 3.em is based on the current font size, rem is based on the root element font, suitable for elastic fonts and unified theme control; 4. Viewport units (vw/vh/vmin/vmax) are adjusted according to the screen size, suitable for full-screen elements and dynamic UI; 5. Auto, inherit, initial and other values are used to automatically calculate, inherit or reset styles, which helps to flexibly layout and style management. The rational use of these units can improve page flexibility and responsiveness.
