A favorite choice of many developers for swiftly designing modern, reactive websites is always Tailwind CSS. Tailwind CSS employs a utility-first approach to allow for more control over styles without having to write custom CSS. In its v4, Tailwind CSS has become even more forward-looking and now offers a lot of new features which enhance developer’s experience and efficiency. Here are some of the most remarkable changes in this latest version.
Key Features:
- Oxide Engine: It is based on Rust, enables parallel processing, significantly reduces build time and speeds up development.
- 10 times faster — We can build our Catalyst UI kit in 55 ms instead of 341 ms, or the Tailwind CSS website in 105 ms instead of 960 ms.
- Smaller footprint — New engine is over 35% smaller with heavy native packages we give such as ones rewritten into Lightning CSS from Rust.
- Where it counts — Rust remains out core realising though we moved some expensive parts that could be paralleled.
- Single dependency — The new engine relies exclusively on Lightning CSS.
- Custom records — We developed our own data structures and implemented our own parser for CSS so that we could get nearly two.
- Unified Toolchain: Lightning CSS has an impact on setup efficiency and CSS production speed.
- It handles @import — you don't need to set up or configure a postcss-import tool.
- It adds vendor prefixes — You can quit adding autoprefixer to your projects.
- It supports nesting out of the box — You can flatten nested CSS without any plugins.
- It transforms syntax — It makes modern CSS features like media query ranges and oklch() colors work better in different browsers.
- Modern Web Support: It works with container queries and native cascade layers to make CSS more responsive and organized.
- Real @layer rules are now in use solving many specificity issues we've struggled with before..
- @property helps us create our own custom properties with specific types and limits. This lets us do things like smooth transitions for background gradients.
- Color-mix makes it easier to change the opacity of currentColor or use our opacity modifier syntax with CSS color variables.
- Container queries in core — With new @min-_ and @max-_ variations to handle container query ranges, we've added support for container queries to core.
-
Composable Variants: More flexibility to create unique variations for custom style.
-
Zero-Configuration Content Detection: Style that adapts to content reducing setup work.
-
Improved Typography: Better tools and font choices to improve the writing style.
-
Accessibility: Continued focus on accessibility with built-in utility categories for general accessibility standards.
