Utility-first, long classes, compact final CSS — against "pure" HTML, complete freedom and the usual cascades. In 2025, the dispute flared up with renewed vigor. Let's analyze the facts calmly. 🚀
🌀 What is Tailwind CSS
Tailwind is a utility-first framework: you describe styles directly in the class attributes. Instead of layers of custom CSS, there is a set of small utilities: indents, colors, shadows, breakpoints.
⚡ Speed: less switching between files.
🧭 Consistency: a single scale of indents, colors, typography.
🧹 Clean bundle: purge removes unused classes.
🧱 Out-of-the-box design system: tokens in tailwind.config.
💡 Button without CSS file: class="bg-blue-600 text-white px-4 py-2 rounded-lg"
📐 Classic layout
Classic — separate CSS/SCSS files, semantic classes and cascade. HTML remains clean, and styles are an independent layer.
📖 Readable HTML: no "garlands" of utilities.
🎨 Maximum flexibility: any CSS capabilities without API restrictions.
🧰 Convenient for a unique design: less struggle with preflight/normalize.
🧩 The BEM/ITCSS pattern helps to keep order in large code bases.
⚖️ Pros and cons — in short
Criterion | Tailwind CSS | Classic CSS |
|---|---|---|
Development speed | 🚀 High (everything in HTML) | 🐢 Below (context-switching) |
HTML readability | 🤯 Decreases on complex components | 📖 High |
Scalability | 🧱 Excellent: tokens, presets, macros | 🔧 Depends on CSS architecture |
Design flexibility | 🎚️ Good, but within the framework of utilities | 🎨 Maximum freedom |
Bundle size | 🧹 Small thanks to purge | 📦 Growing without discipline |
Training for beginners | 📘 You need to learn the "vocabulary" of utilities | 🧭 Lower threshold — clean CSS |
Reuse | 🔁 Extract classes/components, @apply | 🔁 Mixins/utilities/var() |
🧠 DX and team support
🔍 Search for styles: with Tailwind everything is visible in the markup; with CSS we search by selectors.
👥 Onboarding: Tailwind accelerates "entry", but requires knowledge of shortcuts and breakpoints.
🧩 Design systems: Tailwind simplifies token compliance; classic is more flexible, but discipline is critical.
🛠️ Technical nuances
🎯 Semantics: remember about aria-*, contrasts, focus-styles.
🧪 State styles: in Tailwind it is convenient through hover:, disabled:, data-*.
📦 SSR/isomorphism: keep an eye on purge with dynamic classes.
🧶 Complex components: take out repetitive "garlands" into components/presets.
🧭 And what to choose in 2025?
Quick start, tight deadlines? Tailwind: Build your interface faster. ⚡
Unique art-oriented design? Classic: freedom and a perfect fit. 🎨
A large team and a single style? Tailwind: tokens and consistency. 🧱
A long-lived platform project? Classic + strict architecture (BEM/ITCSS). 🏗️
🧩 Combined path: Tailwind for grid/indents/standard patterns + thin custom CSS layer for branded components.
🔬 Mini case
The startup launched an MVP on Tailwind and released a public beta version in 3 weeks. After 6 months, when the brand guide became more complex, we moved some of the utilities into abstract components and added a small SCSS layer for unique animations. The result is fast development without compromising on style.
🧵 Results
Tailwind — speed, consistency and a small bundle, but the risk of "noisy" HTML.
Classic — clean markup and maximum freedom, but you need a rigid architecture.
The golden mean is a mixed approach and discipline in code review.
