What functions are impossible to achieve with css style sheets?

CSS (Cascading Style Sheets) is a style sheet language used to describe the appearance of web pages. It can control the size, color, font and other appearance effects of page elements, making web design more beautiful, clear and concise. However, despite its powerful control capabilities, CSS still cannot achieve certain functions. This article will give you a detailed introduction to the functions that CSS style sheets cannot achieve.

1. Dynamic effects

Although CSS can achieve certain dynamic effects, such as mouse hovering, changing element effects when clicked, etc., it cannot achieve truly dynamic effects, such as elements. Smooth transition, animation effects, mouse drag, etc. These functions require the use of Javascript or other scripting languages ​​with CSS to implement.

2. Logical judgment

CSS cannot make logical judgments, such as judging the current browser window size, screen resolution and other factors, so as to select different CSS style sheets or CSS properties. These functions need to be implemented using Javascript or other scripting languages.

3. Functional interaction

CSS cannot realize the interaction between the user and the web page, such as responding to the user's input, storing the user's input, etc. These functions require the use of Javascript or other scripting languages ​​with CSS to implement.

4. Server-side processing

CSS cannot directly process server-side data. For example, operations such as obtaining data from the database and submitting data must be processed through the server-side, not just through CSS. .

5. Browser plug-ins

CSS cannot run directly in the browser like browser plug-ins, so it cannot implement more complex and powerful functions like browser plug-ins.

6. Cross-browser compatibility

Although CSS can achieve cross-browser effects on web pages, due to the differences between different browsers, CSS cannot guarantee that it will work in different browsers. To achieve the same effect, you need to write different versions of CSS style sheets.

7. Chinese Pinyin Style

CSS cannot directly set the font, color and other styles of Chinese Pinyin. This needs to be achieved through Javascript or other scripting languages.

In short, although CSS style sheets are really powerful and flexible in terms of appearance and layout, they still have many limitations, which also limit the depth and breadth of web design. With the development of Internet technology in the future, perhaps we can find better technologies to avoid these problems.
