This week, we’re bringing you a fresh batch of Tailwind goodness, from a key performance fix in v3.4.8 to myth-busting insights on utility-first CSS. Plus, we take a closer look at the sleek redesign of Deno’s site and introduce a handy new Tailwind plugin for viewport-based animations. Let's dive in! ## **🌟 News** No major news in the ecosystem this week except for the [v3.4.8 release](https://github.com/tailwindlabs/tailwindcss/releases?ref=tailwindweekly.ongloat.com), which fixed a potential performance issue with some specific glob patterns on the content property. The issue was [documented on Twitter](https://x.com/timneutkens/status/1783851267237781574?ref=tailwindweekly.ongloat.com) a few months ago, and the amazing [Robin](https://x.com/malfaitrobin?ref=tailwindweekly.ongloat.com) came up with a clever [fix](https://github.com/tailwindlabs/tailwindcss/pull/14140?ref=tailwindweekly.ongloat.com). See another Twitter thread [here](https://x.com/adamwathan/status/1821286325259239554?ref=tailwindweekly.ongloat.com). ## **📚 Learning** ### **[Utility First CSS Isn’t Inline Styles](https://www.youtube.com/watch?v=g6wtyg3O4Fo&ref=tailwindweekly.com)** Sarah Diang’s talk brilliantly dispels the myth that utility-first CSS is just fancy inline styles. She explains how atomic classes, unlike inline styles, are part of a modular system that offers powerful features like media queries and pseudo-classes, making them far more flexible and maintainable. If you have a dev friend still skeptical about Tailwind CSS they this is a good talk to recommend to them. ### **[What is a Component Library and Should You Build Your Own?](https://component-odyssey.com/articles/10-what-is-a-library-should-you-build-your-own?ref=tailwindweekly.com)** This piece dives deep into the concept of component libraries, exploring what they are and whether you should build your own. I liked that it draws parallels between web development and music albums, mentioning how component libraries save time, reduce repetitive work, and ensure consistency across projects. ### **[How to use aria-current in Tailwind](https://www.youtube.com/watch?v=910m7o1xdMA&ref=tailwindweekly.com)** In this brief tutorial, Chris shows how to style navigation links in Tailwind CSS when using the aria-current="page" attribute for accessibility. By extending the aria object in the Tailwind config file, Chris creates a custom style that underlines the current page link, making it visually different for sighted users while also ensuring screen readers can accurately identify the current page. ## **💅 Showcase** ![](https://tailwindweekly.com/content/images/image-194.jpeg) ****[Deno](https://deno.com/?ref=tailwindweekly.com)** I previously featured the Deno site before but they recently did a redesign and the new site looks sooo good 😍. The dark theme gives it a sleek, modern feel, while the green accents add just the right touch of vibrancy. The typography is clean, and the use of space is impeccable—nothing feels crowded or overwhelming. I love how the site guides you through its features with clear, concise sections, each highlighting what Deno has to offer. ## **🎁 Resource** ![](https://tailwindweekly.com/content/images/image-195.jpeg) ****[tailwindcss-intersect](https://github.com/heidkaemper/tailwindcss-intersect?tab=readme-ov-file&ref=tailwindweekly.ongloat.com)** This cool plugin lets you leverage the power of the Intersection Observer API right within Tailwind's utility classes. Think of it as adding :hover-like states but based on an element's visibility in the viewport—like making an element fade in as it scrolls into view. It's super easy to integrate, just a few lines in your config, and you're good to go. ## **👌 Cool Stuff** Some of these are affiliate links, so I get compensated in some way if you buy through them at no cost to you. **["Level up with Tailwind CSS"](https://shrutibalasa.gumroad.com/l/level-up-with-tailwind-css?ref=tailwindweekly.ongloat.com)** by Shruti dives into real-world Tailwind examples and **offers tips even seasoned users will find valuable**.
