What Are CSS Snippets?

CSS snippets are small blocks of CSS code that perform specific styling tasks. These can range from aligning elements with Flexbox to creating complex animations with just a few lines of code. By embedding them into a project, developers and designers can implement advanced visual features quickly and efficiently.

Importance of Snippets in Modern Web Design

In 2025, the emphasis on speed and efficiency in web design has never been higher. Snippets help reduce repetitive coding, improve maintainability, and make prototypes more interactive and aesthetically pleasing in record time.
