Tailwind CSS
utility-first CSS framework
Tailwind CSS is an open-source CSS framework. Unlike other frameworks, like Bootstrap, it does not provide a series of predefined classes for elements such as buttons or tables. Instead, it creates a list of "utility" CSS classes that can be used to style each element by mixing and matching.
For example, in other traditional systems, there would be a class message-warning that would apply a yellow background color and bold text. To achieve this result in Tailwind, one would have to apply a set of classes created by the library: bg-yellow-300 and font-bold.
As of 23 June 2026, Tailwind CSS has over 95,700 stars on GitHub.
Features
Utility classes
The utility-first concept refers to the main differentiating feature of Tailwind. Instead of creating classes around components (button, panel, menu, textbox ...), classes are built around a specific style element (yellow color, bold font, very large text, center element...). Each of these classes is called a utility class.
There are many utility classes in Tailwind CSS that enable control over a large number of CSS properties, such as color, borders, display type (display), font, font size, layout, and shadow.
This brief starts where responsible research should: with the source description of “Tailwind CSS” as utility-first CSS framework. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as utility-first CSS framework. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 3, 2026. The linked authority identifier is Q102173844. 1 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2026.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
