Deep dives
Tailwind CSS: A CSS Framework for Faster Website Styling
Tailwind CSS, created by Adam Wathan in 2017, aims to simplify website styling by providing a low-level abstraction over CSS properties. Unlike traditional frameworks with pre-styled components, Tailwind offers numerous classes for individual CSS properties, allowing for quick and customized styling. By combining these utility classes, developers can style elements efficiently, such as creating a blue link with specific properties using a series of classes. Tailwind's approach focuses on speed and flexibility in custom designs, making it a popular choice for developers seeking a faster styling workflow.
Tailwind CSS Configuration: Shifting to CSS for Simplicity and Native Feel
In Tailwind version 4, a significant shift in configuration involves moving away from JavaScript configuration files to CSS for simplicity and a more native feel. Instead of a JavaScript configuration file, users now define their color palettes, fonts, and other design aspects in a CSS file using new constructs like @theme rule. This shift aims to streamline configuration, making it more intuitive and integrated with the styling process. By allowing designers to define design tokens directly in CSS, Tailwind enhances the developer experience and simplifies the project setup, creating a more cohesive approach to website styling.
Optimizing Tailwind CSS with Lightning: Flattening Nesting for Efficiency
Tailwind CSS utilizes the Lightning CSS post-processor for flattening nesting in CSS, enhancing the framework's efficiency and reducing code size. By leveraging CSS nesting capabilities, Tailwind simplifies complex features like variants and custom classes, making the code lighter and easier to manage. Lightning processes Tailwind's generated CSS, flattening nested rules for optimal performance and readability. This post-processing step ensures that the final CSS output is streamlined and optimized for browser rendering, improving Tailwind CSS's overall performance and usability.
Origins of Tailwind CSS and Sustainability
Tailwind CSS was able to be sustainable due to the commercial success of the book 'Refactoring UI' that generated significant revenue, allowing the development of Tailwind CSS. The launch of Tailwind UI provided styled website components leading to further business growth and hiring of additional staff. This success showcased a model where open source tools can benefit from a commercial aspect.
Challenges and Criticisms of Tailwind CSS
Despite its success, Tailwind CSS faces criticism for its approach merging presentation with markup and the lack of control over style application order. These issues, although not prominent in public discourse, concern the project creators. Concerns about bundle size due to repeated strings in JavaScript and CSS are acknowledged, with ongoing efforts to optimize these aspects for better performance.
This week we talk to Adam Wathan, the creator of Tailwind CSS. We go into all the changes for Tailwind CSS v4, discussing how they use Rust and Lightning CSS. Adam also shares about how they've been monetizing the tool and building out Tailwind Labs. We also address some of the heated feedback from the Twitter.
