css cannot be

CSS cannot be a universal language because it has its own limitations and some inevitable shortcomings.

CSS (Cascading Style Sheets) is an important part of front-end development, which controls aspects such as the layout, style, and appearance of the website. However, CSS can make developers uncomfortable due to some inherent issues. The following are several aspects that CSS cannot do:

1. Cannot fully control the layout

CSS can make the layout flexible, but it is still not perfect. Sometimes the layout elements are too complex, which makes it more difficult to use CSS. Even with layout modules such as Grid or Flexbox, they cannot meet all situations. In some cases, in order to achieve specific effects, other languages ​​such as JS have to be used.

2. Browser compatibility issues

CSS behaves differently in different browsers. Sometimes, even if the CSS code is written correctly in one browser, it may produce completely different results when run in another browser. Therefore, developers must do a lot of testing and tweaking to ensure that their code works properly across different browsers.

3. Unable to create dynamic effects

Although you can use CSS to create some interesting animation effects, such as simple animation effects such as transitions, rotations, and flickers, there is a lack of more sophisticated animation effects. Complex controls, such as controlling the movement trajectory of objects, etc., cannot achieve significant animation performance. To achieve truly interesting and adaptive animations, JS and other technologies can be used to assist.

4. Unable to handle large-scale styles

If your website design requires large-scale adjustment of styles, or there are many elements that need to be styled, you will find the syntax and structure of CSS Not quite suitable for this situation. To solve this problem, you can use a preprocessor like SASS or Less, or use modular CSS like modules like BEM or SMACSS.

5. Difficulty in debugging

Once a CSS error occurs, debugging becomes extremely difficult. For starters, a small error in CSS can cause problems with the entire layout. When debugging, you need to use professional developer tools, such as Chrome DevTools and Firebug, to more easily locate and fix problems.

In short, although CSS is an essential part of front-end development, it still has shortcomings and limitations. Developers need to understand these limitations and choose the right tools and techniques to solve the problem to achieve better results.
