Tailwind CSS.
Tailwind CSS is a utility-first CSS framework that allows developers to create designs directly in HTML with predefined CSS classes — without needing to write custom CSS files. In 2026, it is the most popular CSS framework.
Tailwind CSS — Explained in Detail
Tailwind CSS is a utility-first CSS framework that provides individual CSS utility classes instead of predefined components (like Bootstrap): 'bg-blue-500' for a blue background, 'text-lg' for larger text, 'rounded-2xl' for rounded corners, 'hover:scale-105' for a hover effect. These classes are combined directly in HTML/JSX — eliminating the need to maintain separate CSS files.
Why Tailwind CSS has revolutionized web development: No more naming conflicts (every class is globally unique), consistent design through a configured color system and spacing scale, automatic purging (unused CSS code is removed — the final CSS file is often only 10–30 KB), and significantly faster development (no context switching between HTML and CSS). Tailwind CSS is used by Vercel, Shopify, GitHub, and Netflix.
For Swiss SME websites, Tailwind CSS offers tangible advantages: Faster development (30–50% less development time), smaller CSS bundles (better performance), easier maintainability (styles are visible in markup, not hidden in separate files), and responsive design out of the box (sm:, md:, lg: prefixes for breakpoints). DLM Digital uses Tailwind CSS in combination with React for all client projects.

For custom designs: Yes. Bootstrap delivers pre-built components — all Bootstrap sites look similar. Tailwind CSS gives you full design freedom with utility classes. Tailwind also produces significantly smaller CSS code (10–30 KB vs. 150+ KB with Bootstrap). However: Bootstrap is more beginner-friendly and still useful for quick prototypes without custom design.
That's the most common criticism. In practice: With component-based development (React, Vue), Tailwind classes are encapsulated in reusable components — the complexity is managed. Additionally: Tailwind classes are immediately understandable ('bg-white text-lg rounded-xl') — unlike abstract CSS class names ('card-wrapper-inner-v2'). Readability is a matter of habit and is no longer an issue after 1–2 weeks.
Technically yes, via a custom theme or a page builder like Oxygen that supports Tailwind classes. In practice: Tailwind CSS reaches its full potential in combination with React/Vue and component-based development. With WordPress projects using ready-made themes, Tailwind adds little value. For custom WordPress themes or headless WordPress, Tailwind is an excellent choice.
