Set up Tailwind’s class‑based dark mode, configure purge for dark utilities, verify CSS output, and toggle dark mode in the browser with a simple button.
Tailwind dark mode forces a choice: media query or class toggle. This guide compares both strategies, their trade-offs, and a concrete class-based implementation with flash prevention.
When Tailwind's content scanner misses dynamically constructed class names, production builds drop utilities. This guide walks through precise content glob configuration, targeted safelisting, and build-time verification to keep styles intact.
Learn why Tailwind JIT misses dynamically generated class names and how to fix it with safelists or literal strings, plus a quick checklist to keep your CSS small and predictable.
Stop managing massive CSS files and fragile purge configurations. Learn how Tailwind CSS JIT mode generates styles on-demand and enables arbitrary values for a leaner production build.
Tailwind only emits CSS for class names it can literally see in your source. Here's why template-literal classes vanish in production, and how mapping objects and the safelist fix it.
Production builds lose Tailwind styles when the JIT compiler cant find template files. This guide covers version-aware content scanning, safelist patterns, and verification steps to keep bundles small and styles intact.
An architecture note on Tailwind CSS's utility-first model: how build-time content scanning drives the smallest production bundle, where the trust boundary lies, operational checks to catch scanner misses, and failure modes that force a design change.
Learn how Tailwind CSS arbitrary values let you inject any CSS utility directly in markup, see a responsive card example, and understand the trade‑offs of bypassing the design system.
