Tailwind CSS has become an essential tool for developers and designers looking for a utility-first approach to CSS. At Junifia, we use Tailwind CSS extensively to build web applications that are scalable, efficient, and visually appealing. With the release of Tailwind CSS v4, the framework takes a significant step forward by introducing features that simplify workflows and improve performance. Here’s everything you need to know about this exciting update.

The highlights of Tailwind CSS v4

1. New default color palette

Tailwind CSS v4 introduces a completely redesigned default color palette. These new colors are carefully chosen to offer more modern and versatile options, ensuring fresh and professional designs. Whether you’re working on a sleek corporate interface or a creative and dynamic project, this updated palette will meet your needs.

2. Native CSS nesting support

One of the most anticipated features of v4 is native CSS nesting support. This improvement simplifies the way you write CSS by allowing you to nest selectors directly within parent rules. Developers no longer need third-party tools to use nesting, which makes the workflow faster and more intuitive. Example:

.button {
  @apply bg-blue-500 text-white;
  &:hover {
    @apply bg-blue-700;
  }
}

3. Optimized performance

Performance is a cornerstone of Tailwind CSS, and v4 improves it even further. The new version offers faster build times and smaller file sizes, making your development process more efficient and your applications more responsive.

4. Major changes

As with any major update, there are some important changes in v4. These changes are intended to ensure long-term improvements but may require adjustments in your projects. The main updates include:

• The removal of deprecated utilities from previous versions.
• Changes in some default configurations.

For a complete list, check the official v4 documentation.
