The difference between css and css

CSS (Cascading Style Sheets) is a language used to describe the appearance and layout of Web pages. CSS is a style sheet language separate from HTML. Using CSS, web developers can easily customize the look and layout of web pages. CSS can be used together with the HTML language to provide rich visual effects for Web pages.

CSS3 is an upgraded version of CSS, which has richer style options and more powerful browser support. CSS3 has many new features and properties, including rounded borders, gradient backgrounds, multi-column layouts, animation effects, transition effects, shadows, and more. These features not only make the page design more beautiful, but also improve the user experience and expand the field of web development applications.

So what is the difference between CSS and CSS3 in specific implementation? First of all, in terms of writing syntax, CSS3 will add some new grammatical rules and attributes, such as Flexbox, Grid, Column, multiple backgrounds, gradients ( Gradient), animation (Animation), media queries (Media Queries), etc. At the same time, CSS3 also allows programmers to implement more flexible and diverse visual styles.

Secondly, in terms of browser compatibility, CSS3 provides better compatibility than CSS. Almost all mainstream browsers support CSS3. This means that web developers can develop with CSS3 features more confidently without having to worry about them not displaying properly on some browsers.

In addition, CSS3 has also made a lot of progress in performance optimization. For example, the animation effects of page elements previously needed to be implemented in JavaScript, but now through the animation properties of CSS3, we can use less code to achieve smoother dynamic effects.

In short, the difference between CSS and CSS3 is that web developers can use more style effects and layout methods, which are not only better in visual effects, but also better in terms of performance, ease of use and responsive design. There are advantages. For developers who want to achieve better design and perfect user experience in the field of web development, mastering the skills of CSS3 is essential.
